Berson UV systems disinfect effluent before discharge into Desna River

Berson has supplied two of its InLine+ UV disinfection systems to the wastewater treatment plant (WWTP) in the city of Chernihiv (population 350,000), north-east of Kiev, the Ukrainian capital. The Berson UV systems disinfect effluent prior to its discharge into the Desna River.

“Disinfection is necessary to meet Ukrainian bathing water standards and also to prevent effluent with high microbial loads of pathogenic viruses, parasites and bacteria entering the Desna River, which is also the main water supply for many communities downstream, including Kiev,” commented Chernihiv’s waterworks director, Sergey Shkin.

“Chemical disinfection with chlorine was not an option as we wanted to avoid unpleasant disinfection by-products such as trihalomethanes (THMs) and Halogenated Acetic Acids (HAAs), which are produced when chlorine reacts with the organic compounds in wastewater. Furthermore, as chlorine is a dangerous gas, additional safety measures are required to comply with rules for its transport and storage and for worker safety – these all carry additional costs.  These factors, together with the fact that many dangerous bacteria and parasites, such as Cryptosporidium and Giardia, are resistant to chlorine, meant we opted for UV technology instead”, he added.

UV disinfection has none of the drawbacks of chlorination – it is completely chemical-free, and produces no unpleasant by-products. It is also simple to operate and maintain.

Chernihiv waterworks selected two Berson InLine 16000 systems, operating in parallel mode. Each UV chamber is equipped with 12 automatically-wiped medium pressure Multiwave® UV lamps and can treat effluent at a flow rate of 2000 m3/h (4000 m3/h in total).  Because of the InLine design of the closed treatment chambers, they have low headloss and are also very compact with a small overall footprint, allowing them to be installed in a very small building. The incoming effluent is gravity-driven.

“We were very impressed by the very compact set-up of the Berson systems,” continued Mr Shkin. “This, together with all the other benefits already described, and also because many other Ukrainian drinking water and wastewater treatment facilities have already installed Berson UV units, helped make our decision to choose Berson.

“Added to this, the fact that the Berson systems are closed and are equipped with automatic wipers means our employees don’t come into contact with the wastewater or the UV from the lamps – this is an additional important safety consideration. Finally, as the UV chambers are very compact with low headloss, we are able to save on construction and pumping costs.”

UV disinfection specialist Berson has launched its new Cyclops UV disinfection system. The compact, single-ended UV system has a 35% smaller footprint than Berson’s larger InLine UV systems, on which it is based, allowing it to be installed in tight spaces or where piping is mounted close to a wall, such as ground water treatment stations or mobile disinfection units.

The single-ended design also means the Cyclops is operator-friendly and can be maintained without requiring any tools: changing a UV lamp takes just two minutes; replacing a quartz tube only takes five minutes; while replacing the entire interior (including the wiper) can be completed in only 15 minutes.

Instead of using screws, all connections utilise snap connectors, while high pressure wing nuts replace conventional nuts, allowing hand-tightening. Both of these features simplify and dramatically speed up routine maintenance. In addition, the wiper is not fitted with a magnet, which prevents iron accumulation. Instead of using a magnet, the wiper has a position indicator sensor mounted on the outside.

UV and H2O2 combine in an AOP-process to destroy pharmaceutical compounds

Berson’s medium pressure UV systems are being used in a trial in the Netherlands to treat hospital wastewater prior to discharge. In the trial, UV is applied in combination with hydrogen peroxide (H2O2) to generate OH- radicals in a so-called “Advanced Oxidation Process” (AOP). The very reactive OH- radicals attack the pharmaceutical residues in the wastewater, breaking them down into H2O, CO2 and harmless metabolites.

Like all hospitals, the wastewater from the Isala Hospital in Zwolle, the Netherlands, contains elevated levels of X-ray contrast compounds and various other pharmaceutical residues.

Prior to UV/ H2O2 treatment the complete wastewater stream is pre-treated in a membrane bioreactor (MBR). The wastewater then passes through a Berson InLine medium pressure UV system, into which specific amounts of H2O2 are injected. The treated wastewater is then discharged as treated sewage into the municipal sewage system.

This is the first full-scale trial for the treatment of hospital wastewater in Europe and is part of the Europe-wide PILLS project, which is investigating which treat¬ment methods are best suited to eliminate pharmaceutical residues from hospital wastewater. At present wastewater plants are not able to remove pharmaceutical residues from their wastewater.

Even though it is unclear what effects these residues have on the water habitat, studies have shown that there is a link between elevated levels of substances such as the hormone ethinylestradiol, which is contained in con¬traceptive pills, and the reproductive rate of fish. The removal of these and other potentially harmful compounds is therefore a priority.

“The pilot plant is going well and Waterschap Groot-Salland, the local water authority which runs the project, has given me very good feedback so far,” said Berson’s European Sales Manager about the installation. “An additional benefit of this system is that it requires high doses of UV which is extremely effective at destroying any microorganisms present in the wastewater,” he added.

“Wastewater reuse is an increasingly important method of creating a new source of water in dry areas like Australia,” says Paul Buijs, Berson’s Managing Director. “In Australia the USEPA validation protocol is the most widely accepted of all the international protocols. Interestingly, despite being a drinking water protocol, USEPA validation is often demanded for water reuse applications,” he added.

“The NWRI protocol is the only wastewater standard in the world, so having this validation, while it is not well known in Australia, is also highly beneficial,” concluded Paul.

Berson (www.bersonuv.com) is a UV disinfection specialist based in the Netherlands, with installations worldwide. The company manufactures UV disinfection systems for municipal drinking water, wastewater and reuse applications.

UV disinfection specialist Berson has helped the Wilsonville Power Systems Development Facility in Alabama, USA comply with strict wastewater discharge regulations. In four years of operation, contaminants have been kept within permit limits with minimal maintenance.

Berson OpenLine UV disinfection system ensures coal power research facility meets strict wastewater discharge regulations

The Wilsonville Power Systems Development Facility (PSDF) is a research and development centre that tests coal-based technologies before they are implemented at power supply facilities. In 2006, the growing plant employed 200 people and produced a wastewater flow of about 95 litres per minute. With its size expected to double in the near future, the facility was required by state and local regulators to start disinfecting its wastewater. The existing wastewater treatment facility in Wilsonville was too far away for the facility to connect. Therefore, the PSDF decided to build its own wastewater treatment facility.

After evaluating competing products, Wilsonville PSDF decided that Berson’s OpenLine UV disinfection system most closely met with their specifications and budget requirements. The OpenLine is an open channel disinfection unit, which uses low pressure, high output UV lamps to destroy microorganisms’ reproductive abilities on a cellular level. The facility installed the OpenLine system in 2007 as the last item in the plant process, providing final treatment of the water before it is discharged into a local river.

The state permit required that no single sample of the water leaving the Wilsonville PSDF could have more than 200 faecal colonies per 100 ml. The OpenLine system has provided the necessary disinfection required to meet the site’s permit. In addition, the system offers a compact footprint and requires virtually no maintenance. The OpenLine has operated for 21,000 hours since installation, meeting disinfection requirements without needing UV lamp replacement.

Facility safely treats wastewater and rejuvenates local natural area

UV disinfection specialist Berson has helped the town of Carnation in Washington State, USA create an innovative, environmentally conscientious way of dealing with wastewater, using Berson’s InLine 7500+ UV systems.

Carnation, a community of about 1,900 residents, has never used a central sewage system, relying instead upon individual septic tanks and drainage fields to handle its wastewater disposal needs. However, soil surveys conducted in 1987 revealed that the city’s current wastewater disposal method had become insufficient for the growing population’s needs and continued usage of the current system posed a contamination threat to the local unprotected aquifer. Carnation anticipated its future growth and recognised the associated health and environment problems that could come without a more developed wastewater system.

To deal with this issue, Carnation worked with officials from King County to develop plans for a new sewage system and wastewater treatment facility. Officials chose to integrate a Membrane Bioreactor (MBR) system with UV disinfection technology to ensure that the treated water would be clean and environmentally safe. Reclaimed water would then be discharged to the nearby 24 hectare Chinook Bend Natural Area to foster growth of wildlife and restore the wetlands. The resulting facility was awarded the “Small Project of the Year Award” at the 2008 WateReuse Symposium in Dallas, Texas.

To find UV disinfection equipment suitable for this application, King County turned to Berson (through its US sister company). Berson provided two parallel InLine 7500+ UV units installed in-series after the MBR system. The units are closed vessel, which allows them to flange directly to the piping from the MBR. Each UV unit is capable of treating large volumes of water, with one unit treating up to 5.3 million litres per day, with the second unit providing back-up treatment. The system utilises Berson’s medium pressure, high intensity lamps to provide a compact footprint for disinfection. The InLine systems are low maintenance, with automatic mechanical cleaning to keep quartz sleeves surrounding each UV lamp deposit free.

The Carnation wastewater plant’s discharge is Class A, the highest quality level of reclaimed water recognised by the state of Washington. Water is released into Chinook Bend Natural Area throughout the year, except during maintenance periods when output can be switched to the nearby Snoqualmie River.

According to Carnation wastewater plant supervisor, Dan Zimmer, the UV equipment’s performance has met expectations producing reclaimed water for the facility without any permit violations. In May 2010, after two successful years of operation, the automatic cleaning system had worked flawlessly and the UV lamps only required a single change. “The UV equipment at the Carnation site has performed well, requiring minimal maintenance. I would recommend Berson’s closed vessel UV systems to another plant,” said Zimmer.

New ‘plug-and-play’ modular system is 100% pre-engineered for wastewater applications

UV disinfection specialist Berson (www.bersonuv.com) has launched its new OpenLine range of open channel UV wastewater treatment systems. 100% pre-engineered for wastewater applications, the OpenLine range is specifically designed to treat secondary wastewater flows of up to 95,000 m3/day (approx. 4,000 m3/hour) over a wide range of UV transmittances. It utilises a new type of low pressure, high output (LPHO) amalgam lamp that offers stable UV output over its entire operating life of up to 14,000 hours.

The OpenLine range’s flexible, modular design means simple installation and maintenance, making it the ideal open channel UV system for municipalities with low flow requirements. Inspired by Berson’s successful InLine+ range of closed vessel UV systems, the OpenLine is the first ‘plug-and-play’ open channel UV system available on the market. Installation is straightforward: the unit is simply placed on a flat surface, the inlet and outlet piping is connected, and it is ready to use. The totally self-contained unit negates the need to install lamp wires through conduits or connect chemical feed systems.

Automatic, long-life Viton wipers, powered by a self-contained air compressor, keep the quartz sleeves surrounding the UV lamps clean, ensuring optimum UV output at all times. Wiper frequency is also easily adjustable. The system’s ballasts have a variable output between 50-100% and are easily accessible. In addition, the interface of the PLC control system can be customised by the user to suit their requirements. Lamp replacement and other routine maintenance tasks are also straightforward and can usually be carried out by on-site staff.

Berson 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, Parts 1, 2 & 3 – the highest standard currently possible in the world. The company’s UV systems are also validated to the UVDGM** and NWRI*** (for reuse applications) in the USA and Canada.
