Introduction

The UV disinfection industry has experienced tremendous growth over the last 20 years.  The development of new UV technologies over this period is a perfect example of an industry investing to meet market demand – in this case demand for an effective, low cost, and environmentally friendly way to disinfect wastewater for reuse.

The acceptance of UV disinfection at wastewater plants treating in excess of one billion gallons daily is proof that UV is no longer an ‘emerging’ technology, but rather an accepted technology to be used routinely by engineers to safeguard human health and alleviate environmental pressures.

Wastewater reuse has been practiced in various forms for decades, with the United States leading the way in reuse research. It is now a major issue in the US where large areas of the Western and Southern states experience chronic water shortages. The problem is becoming more acute with many of the most arid states, such as Nevada and Arizona, experiencing rapid increases in their urban populations since the 1990s. Large-scale reuse projects are now also being considered in other water-poor regions of the world such as Australia, southern Europe and China.

New Technology

The use of computational fluid dynamics (CFD) modelling has vastly improved UV equipment manufacturers’ ability to predict with confidence the level of treatment required for wastewater using their proprietary equipment. All manufacturers will soon use this tool to optimize the dose delivery of their reactors and minimize energy costs. Also, as manufacturers develop and improve optimized UV reactors, they will be able to validate the designs using USEPA, NWRI or European validation protocols.

Conventional UV lamp technology will also improve over the coming years, with medium pressure lamps continuing to see gains in energy efficiency, lamp life and power density, and Quartz coating techniques extending lamp life to well over 12,000 hours.

Concerns

A major concern to the UV industry is the issue of microbial reactivation – the apparent ability of some microorganisms to repair the damage done to their DNA by UV, reactivating their ability to infect.  DNA repair can occur in a closed (dark) system, but is more likely in open systems under direct sunlight (photoreactivation). The dose level and lamp type seem to affect the degree of reactivation, with low pressure (single wavelength) UV lamps appearing to be more susceptible to photoreactivation than medium pressure (multi-wavelength) lamps (see reference 1). A much larger research effort into the area of photoreactivation is required and will most likely be forthcoming over the next five years.

A significant amount of research has also targeted the question of UV disinfection by-products (DBPs), specifically the most common water constituents such as chlorine, bromide, nitrate, ozone, natural organic matter and iron. At normal UV disinfection doses no significant disinfection by-products have been shown to form.

Benefits of UV for the reuse market

The most common method of wastewater disinfection for reuse has long been chlorination. Despite chlorine’s impressive track record, concerns regarding DBPs and, more recently, disinfection performance with respect to pathogen inactivation, are driving the conversion from chlorine disinfection to other disinfection methods such as UV, which does not produce any DBPs.

Closed vessel UV systems are easy to install within existing pipework, so there is minimal disruption to plant operation. Day to day operation is simple and only minor maintenance is needed. The only regular requirement is changing the UV lamps and wiper rings once a year, a straightforward operation that can be carried out by on-site personnel.

UV systems for wastewater reuse are also validated to much higher doses than drinking water systems, according to protocols established by the National Water Research Institute (NWRI). Drinking water type product validation, with the accompanying rigor, will emerge as the dominant method of assessing suitability for these critical applications. The ability to prevent photo repair will also emerge as key.

Applications for wastewater reuse

Potential applications for wastewater reuse are extremely wide-ranging and include any instance where water is needed for non-potable or indirect potable use. The most popular and widespread use is for agricultural irrigation, with the USA leading the way, but with China and a number of Australian states also making significant progress. Other irrigation uses include landscape and recreational applications such as golf courses, parks, and lawns.

Reclaimed wastewater is also used for groundwater recharge applications such as aquifer storage and recovery or preventing saltwater intrusion in coastal aquifers. Other uses include toilet and urinal flushing, fire fighting, foundation stabilization in the construction industry and artificial snow generation. In all these applications, reuse wastewater relieves the burden on existing municipal potable supplies.

The Singapore Water Reclamation Facility (NEWater), a joint initiative between the Singapore Public Utilities Board (PUB) and the Singapore Ministry of the Environment and Water Resources, is a well-known example of water reuse on a large scale. NEWater is treated, used water that has undergone a stringent purification and treatment process using advanced dual-membrane (microfiltration and reverse osmosis) filtration and UV disinfection. The primary use of NEWater is for wafer fabrication processes and other non-potable applications in manufacturing processes. However, the PUB also uses NEWater for indirect potable use by mixing and blending it with raw water in reservoirs prior to conventional treatment at waterworks for supply to the public for potable use. According its website, the PUB currently adds 3 mgd of NEWater (about 1% of total daily water consumption) into raw water reservoirs, and the amount will be increased progressively to about 2.5% of total daily water consumption by 2011.

Case study – Arizona, USA

Two golf courses in the town of Anthem in Arizona, USA are using UV-treated wastewater for irrigation. Founded just over 10 years ago Anthem, a town just north of Phoenix, now has a population of over 40,000. As part of its rapid expansion the town recently installed three closed chamber, medium pressure UV system from Berson’s US sister company Aquionics to disinfect its wastewater. This allows the town to not only meet increased demands in its water and wastewater treatment capacity, but also to exceed the output quality standards.

“The wastewater is treated by three Berson InLine systems handling a combined flow of three million gallons (over 11.3 million litres) per day,” explained Anthem’s wastewater Foreman Jeff Marlow. “They work in conjunction with microfiltration and nitrification/denitrification. We chose the Berson UV systems because they are optimised to meet the Arizona Pollutant Discharge Elimination System (AZPDES) Permit Program,” he added.

The two local golf courses currently use a combination of UV treated wastewater and fresh river water for irrigation, but with increase in population, it is expected that the courses will soon be using wastewater exclusively.

An automatic cleaning mechanism keeps the lamp sleeves free of organic deposits for consistent UV dosing. Each chamber is also fitted with UV monitors to measure actual UV dose for record keeping. With the addition of an optional online transmittance monitor, real time transmittance values are used to automatically adjust the dose pacing of the UV system.

Conclusion

The UV industry has matured considerably over the last decade and is now highly regulated and dominated by the world’s major water technology companies. Conventional UV technologies have been field tested and now have considerable track records in a wide range of applications. Uncertainties surrounding regulations, royalties, technology and engineering have decreased and acceptance of UV is expected to grow rapidly over the next 20 years. Conventional UV designs have been greatly aided by CFD, which will be used as a routine sizing tool for future designs.

The stage is now set for dramatic growth in the wastewater reuse market, especially with increasing populations putting even more pressure on already overstretched water resources in many regions of the world. Tighter limitations on pollution discharge will also play an important role in the development of this technology.

Cambridge Water plc in the United Kingdom has recently installed three Berson InLine+ DVGW*-validated medium pressure UV disinfection units at the remote Euston drinking water pumping station in Suffolk. Between them the three units treat up to 724m3/hour of water, which is then delivered via a 55km delivery main to storage reservoirs that serve the city of Cambridge.

An important feature of the Berson UV system provided to Cambridge Water is its UV-Tronic+ V5 PLC controller, the latest version of Berson’s UV-Tronic controller range. Based on a rugged industrial PLC and with an RS485-based Modbus interface, the UV-Tronic+ V5 links to the site’s SCADA control system and allows users to set up and manage the UV system’s operating parameters to exactly match their requirements.

Older versions of the UV-Tronic already had the capacity to control multiple streams and treatment chambers, a particularly useful feature where a treatment plant has variable water parameters such as flow or transmittance, as it allows shutdown of individual UV chambers when not required, reducing power consumption. In addition, when UV monitors on the inner wall of the UV chamber register a fall in the UV level, the UV-Tronic is designed to trigger automatic wipers on the quartz sleeves protecting the UV lamps. The wipers remove any built-up deposits on the sleeves, ensuring uninterrupted protection against microbial contamination. A major benefit of automated wiping means no chemicals are required for cleaning, an especially important feature when it comes to drinking water disinfection.

The new UV-Tronic+ V5 has enhanced features which now makes it possible to individually control the power level of up to six UV disinfection chambers simultaneously to suit the flow conditions for each stream, thus further minimising power consumption. Additional new features include greatly extended monitoring and control via Modbus, increased manual control functionality to ease maintenance and servicing, and the capacity to individually calibrate UV sensors when running in DVGW mode. A built-in modem can also be used to provide remote monitoring and diagnosis and for software upgrades.

“The UV-Tronic+ V5 is a very useful feature of the Berson UV system,” commented Bob Clifforde, Cambridge Water’s Electrical Engineer. “By allowing us to control each UV chamber individually it not only greatly simplifies operations but has also reduced our operating costs.”

Providing primary disinfection followed by marginal chlorination using hypochlorite, the UV system was installed as an alternative to chlorine-only disinfection. “We selected UV for this remote location as it is so much more convenient than transporting chlorine from our Cambridge depot, over 50km away. There are savings too over the cost of buying and transporting the chlorine gas,” added Bob.

Berson UV is one of the few non-German UV system suppliers capable of providing a complete range of UV systems with capacities between 10 – 10,000 m3/hour, certified to the newest German DVGW norm, W294, Part 1, 2 & 3 – the highest standard currently possible in the world.

Introduction

UV disinfection technology is one of the fastest growing water treatment technologies today.  The development of new UV technologies over this period has been a perfect example of an industry investing to meet market demand – in this case demand for an effective, low cost, and environmentally friendly disinfection technology. An increasing awareness of harmful disinfection byproducts from traditional chemical disinfection solutions, combined with technological advances in component design and manufacture, process control, hydraulics and microbiology have resulted in UV systems that are as reliable and cost efficient as their chemical equivalents.  With the implementation of standard methods for the testing, design and operation of UV systems have now given the technology the transparency needed for wide scale adoption globally.

With a mandate to ensure public water systems provide safe drinking water to their users, many governmental regulatory bodies around the world have adopted UV disinfection standards.  The vast majority of these drinking water standards reference either the German UV Devices for the Disinfection for Drinking water Supply standard, commonly known as DVGW (Deutsche Vereinigung des Gas und Wassserfaches), or the US Ultraviolet Disinfection Guidance Manual for the Final Long Term 2 Enhanced Surface Water Treatment Rule standard, known as the UVDGM (Ultraviolet Disinfection Guidance Manual).

While the goal of both standards is to ensure safe drinking water, their approach and  outcomes, in terms of operating equipment, is very different. An understanding of these two approaches, their similarities and differences, is therefore helpful to designers, regulators and users alike.

Overview of the DVGW Standard

The German Gas and Water Association (DGVW) first published UV guidelines in 1994, following up with more formal regulations in 1997.  The most recent update, known as Work Sheet 94, issued in 2006, has been implemented as part of the German Drinking Water regulations, thus making compliance a legal requirement in Germany. Along with similar standards established in Austria (ÖNorm 2001 and ÖNorm 2003), these standards are recognized throughout the world and form the basis of many other national standards.

The core ethos of the DVGW (and ÖNorm) standard is that a UV system should be proven to continuously deliver a minimum germicidal fluence of 40mJ/cm2 under all operational conditions. The measured UV Intensity must therefore remain above a specified value for all ranges of flow and UV- transmittance that will occur during operation. The justification for selecting 40mJ/cm2 as an appropriate UV fluence level is based upon the knowledge that many harmful pathogens can be inactivated up to a level of 4-log by exposure to a UV fluence of 40mJ/cm2 (see figure 1).

Figure 1: UV Fluence requirements to ensure 4-log inactivation of multiple pathogens

So as to ensure that a given UV system is able to provide the 40mJ/cm2 disinfection level, the DVGW standard defines a detailed microbiological examination method, or bioassay.  Tests are performed by simulating operating conditions at full scale using B. subtillis spores as a pathogenic surrogate. Subsequent operating UV systems must be constructed and operated under identical conditions, ensuring that at least one fixed UV sensor continuously monitors the germicidal radiation, ensuring it remains above the specified minimum.

The structure of the DVGW standard, shown in Table 1, allows different stakeholders to easily access the information they require. Operators and engineers can look to Part 1 to assist with the planning of both technical and commercial factors of UV systems. The information in Parts 2 and 3, on the other hand, provides manufacturers, testing agencies and regulators valuable details regarding design and validation.

Table 1: Structure of the DVGW standard

One key benefit of the latest DVGW standard is that is harmonizes the allowed UV sensor types with the Austrian standard (although specific sensor calibration processes are yet to be fully implemented).

Some people have pointed to the lack of targeting of specific pathogens as a limiting factor to the implementation of this standard. In addition, as some pathogens, such a Cryptosporidium and Giardia, are inactivated at significantly lower UV fluence levels than 40 mJ/cm2, the capital and operational costs of DVGW compliant UV systems can be high for very large flows. On the plus side, while still keeping the 40mJ/cm2 disinfection level, the 2006 DVGW standard does allow for the generation of performance curves, allowing the operator to limit energy wasting overdosing situations.

The DVGW standard has formed the backbone of drinking water regulations worldwide for almost 15 years and despite of its limitations, it will continue to provide valuable information to operators, engineers, manufacturers and regulators with regards to the design, testing and operation of UV systems for the protection of public drinking water supplies.

Overview of USEPA UVDGM Guideline

While the German DVGW standard states its validity for all water disinfection facilities using UV treatment and covers a broad range of target pathogens, the USEPA’s Ultraviolet Disinfection Guidance Manual (UVDGM) is more limited in its scope. It is specifically designed to cover all public water systems that use UV disinfection for the treatment of surface water (or groundwater under the direct influence of surface water). More specifically it assists with the Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR), requiring additional treatment based on source water Cryptosporidium concentrations and current treatment practices, where UV disinfection is one treatment option. 
 
In summary, the UVDGM outlines how compliance to the very specific inactivation targets for specific pathogens can be achieved, in accordance with the water source and existing treatment employed. Table 2, (Table 1.4 within the UVDGM) shows the specific UV dose requirements for the specifically targeted pathogens.

Table 2: Summary of Microbial and Disinfection Byproduct Rules

One of the core premises of the UVDGM is that UV drinking water systems should be designed, tested and operated in accordance with the targeting of specific pathogens. As such it approaches equipment validation, sizing and operation in a different way than the DVGW standard. The choice of a surrogate test microorganism is not specified. Instead, uncertainty factors are used to account for differences in dose response characteristics.  Additional uncertainty factors are used to account for further experimental variations as well as for UV sensors.

As with the DVGW standard, the UVDGM guideline structures information in order to allow stakeholders ease of access (see Table 3). The threefold stated objectives are summarized as follows:

- Provide operators and designers technical information on selecting, designing and operating compliant UV installations
- Provide tools and guidance to regulators in assessing UV installations throughout design, start-up and operation
- Provide manufacturers and testing agencies standards for design and validation.

Table 3: Structure of the UVDGM

The UVDGM does recognize both the German DVGW and Austrian ÖNorm standards, granting compliant UV systems a 3-log Cryptosporidium and Giardia inactivation credit.  In practice, however, such systems are over-sized when compared with those that have undergone specific UVDGM validation testing.

The equipment validation and operational verification methods outlined in the UVDGM provide a robust, transparent basis for public drinking water UV systems targeting specific pathogens. Together with the draft 2003 guidelines, they have driven the expansion of the use of UV as a safe disinfection technology both in the US and, increasingly, globally. 

Summary

Expanding their influence beyond their national borders, both the German DVGW standard and the USEPA UVDGM have played important parts in helping UV disinfection technology become one of the fastest growing water treatment technologies globally.

Although both standards seek to improve the safety of public water supplies, the latest revisions of the two methods take different approaches, with significant differences in the subsequent capital and operating costs, even when comparing identical UV system designs.

It is hoped that by explaining the similarities and differences, both technical and commercial, this article provides stakeholders with much useful information for the planning, designing, validating and operating UV systems for drinking water applications.

Bersons’ InLine+ serie van middendruk UV-reactoren is de eerste in de wereld die een officiële validatie voor afvalwaterhergebruik heeft verkregen. Na een intensief 3e partij onderzoek door Carollo Engineers in de USA, zijn de reactoren formeel goedgekeurd voor voor toepassing na filtratie en/of  RO van behandeld afvalwater door het California Department of Public Health (de zgn. “title-22-validation”) en goedgekeurd voor afvalwater hergebruik conform de richtlijnen van het Amerikaanse AwwaRF en NWRI (1) .

Al enkele tientallen jaren wordt afvalwater hergebruikt, met name in de USA, waar reeds veel onderzoek op dit gebied is uitgevoerd en validatieprotocollen zijn opgesteld. Vanwege de verdrogingsproblematiek, is hergebruik van afvalwater (in feite “2e hands kraanwater”) een belangrijk thema geworden in droge streken zoals het zuiden en westen van de USA, mediterrane landen, het midden-oosten, Australie en Azie, waar grootschalige projecten voor afvalwater-hergebruik worden gepland en in uitvoering zijn.

Sinds lange tijd is chloreren de meest gebruikte methode van afvalwater desinfectie tbv hergebruik geweest. Hoewel chloreren en andere chemische desinfectiemethodes effectief zijn gebleken, wordt door toenemende zorgen over de vorming van desinfectie-bijprodukten (DBP’s  zoals TriHaloMethanen), toegenomen resistentie van diverse pathogene organismen (zoals Cryptosporidium en Giardia) tegen chemische desinfectie en aangescherpte ARBO-richtlijnen t.a.v. transport en opslag van chemische producten,  steeds vaker overgeschakeld op alternatieve technieken, zoals fysische desinfectie met  UV-licht.

De Berson InLine UV-reactoren zijn eenvoudig te installeren in reeds bestaande leidingsystemen, dus er zijn weinig aanpassingen in een pomp- of waterbehandelings-station benodigd. De bedrijfsvoering is eenvoudig en onderhoud is, vanwege de toepassing van een kleiner aantal middendruk UV-lampen, minimaal. Bij continubedrijf is het slechts eenmaal per jaar nodig de UV-lampen en wisser-ringen te vernieuwen. Dit is een eenvoudige operatie die door het reguliere personeel zelfstandig en in korte tijd kan worden uitgevoerd.

Het toepassingsgebied voor hergebruik van afvalwater is zeer breed en omvat bijna alle projecten waar water wordt gebruikt buiten de toepassing als drinkwater. De meest omvangrijke afvalwater hergebruikprojecten betreffen landbouw-irrigatie en verwante toepassingen zoals golfterreinen, (sport)parken, fonteinen en gazons. Hergebruikt afvalwater wordt ook toegepast voor aanvulling van grondwatervoorraden (zgn. ASR -Aquifer Storage and Recovery- projecten) en preventieprojecten tegen grondwaterverzilting in kustgebieden. Andere toepassingsgebieden van hergebruikt water betreffen toiletspoeling, bluswater, fundamentstabilisatie in de bouw en produktie van kunstsneeuw. In al deze toepassingen voorkomt een verdere aanslag op de produktie en voorraden van drinkwater.

“Wij zijn enorm trots op het behalen van deze belangrijke validatie” vertelt Berson’s Managing Director Andrew Clark. Onze innovatieve technologie gebruikt UV-sensoren die het UV-desinfectieproces continu bewaken, bijregelen en onze klanten direct informeren over de desinfectie-resultaten. Dit maakt een goede controle mogelijk van het desinfectieproces bij een zo efficiënt mogelijk energiegebruik, vooral vergeleken met bestaande methoden, waarbij door toepassing van grote veiligheids-factoren, een groter aantal lampen wordt gebruikt, veelal zonder wissysteem, dus met hogere onderhoudkosten en drukverlies, dus energieverbruik tot gevolg.”

Berson’s InLine+ medium pressure, closed vessel UV systems are the first in the world to gain formal approval for wastewater reuse applications. Having undergone extensive third party testing by Carollo Engineers in the USA, they have been formally approved for post-filtration and reverse osmosis applications by the California Department of Public Health (Title-22 validation) and are now validated for wastewater reuse applications in accordance with AwwaRF/NWRI* guidelines. Berson’s UV systems are sold in North America by its sister company Aquionics Inc.

Wastewater reuse has been practiced in various forms for decades, with the USA leading the way in reuse research. It is now a major issue worldwide, with large areas of western and southern USA experiencing chronic water shortages. Large-scale reuse projects are now also being considered in other water-poor regions of the world such as Australia, Singapore, China and southern Europe.

The most common method of wastewater disinfection for reuse has long been chlorination. Despite chlorine’s impressive track record, concerns regarding disinfection by-products (DBPs) and, more recently, disinfection performance with respect to pathogen inactivation, are driving the conversion from chlorine disinfection to other disinfection methods such as UV, which does not produce any significant DBPs.

Closed vessel UV systems are easy to install within existing pipework, so there is minimal disruption to plant operation. Day to day operation is simple and maintenance is minor. The only regular requirement is changing the UV lamps and wiper rings once a year, a straightforward operation that can be carried out by on-site personnel.

Potential applications for wastewater reuse are extremely wide-ranging and include any instance where water is needed for non-potable use. The most popular and widespread use is for agricultural irrigation and for other irrigation applications such as golf courses, parks, fountains and lawns. Reclaimed wastewater is also used for groundwater recharge applications such as aquifer storage and recovery or preventing saltwater intrusion in coastal aquifers. Other uses include toilet and urinal flushing, fire fighting, foundation stabilization in the construction industry and artificial snow generation. In all these applications, reused wastewater relieves the burden on existing potable supplies.

“We are extremely pleased that we have achieved this important validation,” commented Berson’s Managing Director Andrew Clark. “Our state-of-the-art technology uses UV sensors to actually measure how the UV systems are performing. This permits much greater control while saving energy, especially when compared to the existing methods of applying crude safety factors to systems that use high numbers of lamps or are unwiped.”

Berson UV-techniek introduceert dit voorjaar haar wereldleidende UV desinfectie technologie op de Internationale Beurs en Congres “Wasser Berlin” (standnr. 234 in Hal 2.2). De UV- systemen van Berson UV-Techniek worden over de hele wereld gebruikt voor het desinfecteren van drinkwater en afvalwater zonder gebruik van chemische desinfectie-middelen. 

Het in Nederland gevestigde Berson is gespecialiseerd in municipale toepassingen van haar UV-Technologie en zal haar InLine en InLine+ reeks van UV-reactoren tonen met capaciteiten tot 5000 m3/uur. Deze CFD-geoptimaliseerde UV-reactoren hebben een uniek ontwerp waarbij de middendruk UV- lampen onder een hoek van 90o dwars op de waterstroom staan. Dit garandeert niet alleen een effectievere verdeling en distributie van UV licht naar de passerende vloeistof, maar ook een zeer compacte bouw, waardoor installatie en onderhoud vergemakkelijkt worden. Veel InLine-reactoren zijn gevalideerd volgens de protocollen van DVGW, Ö-norm, US-EPA (drinkwater) en NWRI (afvalwaterdesinfectie).

Berson UV-techniek will be exhibiting its world-leading UV disinfection technology at the Wasser Berlin International Trade Fair and Congress this spring. The company will be located at booth 234 in Hall 2.2. The company’s UV systems are used worldwide for the non-chemical disinfection of drinking water and wastewater.

Based in the Netherlands, Berson specialises in municipal applications and will be showing its InLine and InLine+ range of closed-vessel UV disinfection systems. Capable of treating water and wastewater flows as high as 5000 m3/hour, they have a unique design where the UV lamps are angled at 90o to the water flow. This not only means a more effective distribution of UV light to the passing fluid, it also means a much smaller footprint, allowing easy installation and servicing.

UV Disinfection Specialist to Showcase World-Leading UV Disinfection Technology

UV (ultraviolet) disinfection specialist Berson UV-techniek will be exhibiting at the World Future Energy Summit, being held in Abu Dhabi in January. The company will be showcasing its world-leading UV disinfection technology, which is used worldwide for non-chemical disinfection of drinking water and wastewater.

“The summit is the largest meeting of the most influential figures in the renewable energy industry,” comments Berson’s International Area Sales Manager Simon Robb. “Water re-use is one of the themes of the summit, and as we are one of the leaders in the use of UV for water and wastewater re-use, we considered it important to be represented,” he added.

Berson’s booth will be located in the Netherlands Pavilion, which will also feature many of Holland’s other leading water companies. Holland is one of the nations most at risk from the environmental effects of climate change so, not surprisingly, it is also one of the most forward-thinking in terms of environmental technology.
