Aquionics Photon PMD New Feature Further Reduces Pool Operating Costs

Power Switching allows automatic water monitoring and disinfection

Erlanger, Kentucky (November 18, 2011) – The Aquionics Photon PMD range of UV disinfection systems now further reduces pool operating and maintenance costs with its new Power Switching feature.

Photon PMD disinfection systems were developed for use in swimming pools, water parks and other aquatic leisure facilities. Photon units use UV lights to destroy chloramines, which develop in all swimming pools and cause unpleasant odors, skin and eye irritation and can damage steel structures in surrounding enclosures. Pools using a UV disinfection system also require lower chlorine levels to maintain cleanliness, reducing operating costs for management.

Aquionics’ Photon PMD systems offer the new Power Switching feature, allowing users to automate the UV disinfection process. The new feature continuously monitors the water and maintains a predetermined UV dosage (for disinfection or chloramine control) regardless of bather load or water quality. By reducing unit activity to an as-needed basis, Power Switching extends lamp life and reduces energy usage.

Aquionics and Dot Metrics Sign JDA to Combine Disinfection Technologies

Collaboration will produce unprecedented disinfection products

Erlanger, Kentucky (July 25, 2011) – UV disinfection specialist Aquionics has signed a Joint Development Agreement with LED expert Dot Metrics Technologies (Charlotte, N.C.) to develop a new line of UV-LED disinfection products. The agreement formalizes several months of working together to bring new disinfection systems to the market.

Aquionics and Dot Metrics have signed a Joint Development Agreement to combine efforts.

Dot Metrics is a small company associated with the University of North Carolina at Charlotte. It focuses on UV LED systems development for disinfection of water, air and surfaces. For several years, Dot Metrics has been testing and discovering new applications for UV LEDs.

UV treatment of fluids is replacing traditional chemical treatment in many applications, however it still has a number of drawbacks. UV LEDs overcome almost all the problems associated with standard, mercury-based UV disinfection.

“The joint development effort between Dot Metrics and Aquionics is a great example of a successful collaboration. Dot Metrics brings innovative UV LED expertise and Aquionics contributes its experience and resources to rapidly commercialize the technology and provide access to key markets,” said Dot Metrics President and CEO, Rosanna Stokes. “In addition, access to technology from Aquionics’ sister companies within the water and photonics industries provides a strong basis for a long term relationship. The combined results of our efforts will provide a novel, small footprint, non-mercury based UV disinfection system in the market.”

“The development of UV LED chips has progressed significantly in the last few years to allow commercial adoption. Dot Metrics brings added value in packaging the chips and configuring them in a usable system,” says Aquionics President, Oliver Lawal. “After months of collaboration, we are pleased to announce our formal agreement as we work together towards the completion of a remarkable new range of products.”


Aquionics’ UV Systems Help City Reclaim Wetlands

Facility safely treats wastewater and rejuvenates local natural area

Erlanger, Kentucky (September 23, 2010) – UV disinfection specialist Aquionics helped the city of Carnation in King County, WA create an innovative, environmentally conscientious way of dealing with wastewater, using the company’s InLine 7500+ UV systems.

Aquionics’ UV systems allow Carnation, WA to safely treat wastewater while rejuvenating the Chinook Bend wetlands (inset).

Aquionics’ UV systems allow Carnation, WA to safely treat wastewater while rejuvenating the Chinook Bend wetlands (inset).

Carnation, a city of about 1,900 residents, had 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 recognized the associated health and environment problems that could come without a more developed wastewater system. 

To deal with this issue, Carnation worked with King County officials 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 nearby 59-acre 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 Aquionics Inc.  Aquionics provided two parallel trains of InLine 7500+ units installed in-series after the MBR system.  The units are closed vessel, which allow them to flange directly to the piping from the MBR.  Each train is capable of treating large volumes of water, with one train treating up to 1.4 million gallons per day, while the second train provides back up treatment.  The system utilizes 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 recognized 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, while requiring minimal maintenance.  I would recommend Aquionics’ closed vessel UV systems to another plant,” said Zimmer.

UV Disinfection a Safer Choice for Pools According to U of I Study

Aquionics systems reduce exposure to harmful chemical disinfection byproducts

Erlanger, Kentucky (August 16, 2010) – A study published by Environmental Science & Technology magazine found that chemicals commonly used to disinfect pool water can pose serious health risks for swimmers.  The study, conducted by researchers at the University of Illinois (Champaign, Ill.), shows that exposure to byproducts of chemical disinfection can cause early aging, birth defects, asthma and bladder cancer.  The findings suggest that the best method of pool disinfection is a combination of ultraviolet (UV) treatment and chlorine, rather than the traditional method of chlorine treatment alone.

Aquionics UV systems offer a safer alternative to chemical disinfection.

Aquionics UV systems offer a safer alternative to chemical disinfection.

Aquionics offers a safer method of non-chemical pool water disinfection with its UV systems.  Water circulating through the pool is exposed to a specific spectrum of UV light, which is absorbed by microorganisms’ DNA.  The UV energy prohibits replication and causes permanent, irreparable inactivation of the microorganism.  Chlorine is still required for total disinfection, however pools using a UV system require up to 90% less chlorine than pools without UV.

In addition, UV light initiates photo-chemical and photo-oxidation reactions that destroy chloramines, the byproducts of chlorine disinfection.   This reduces the associated health risks along with unpleasant odors, eye and skin irritation, and corrosion to pool equipment.

Aquionics systems use UV monitors and state-of-the-art Photon controllers to measure and adjust lamp output to appropriate levels.  Automatic wipers keep the quartz sleeves surrounding the UV lamps clean and power switching ensures UV output varies according to demand, ensuring optimum performance at all times.  The systems are compact and can usually be installed within existing pipework.  The only regular maintenance required is changing the UV lamp every six months – a simple operation that can easily be carried out by on-site staff.
