Water & Wastewater Asia Mar/Apr 2018

WATER & WASTEWATER ASIA March / April 2018 14 / IN THE SPOTLIGHT The partnership between Drylet and Nanjing Hoyo Municipal Utilities Investment Administration Group was finalised at the 2017 CEO Delegation to China led by Commerce Secretary Ross during President Trump’s visit to Beijing provides water and wastewater to 7,900 people in rural New Mexico, USA. The organisation’s water and wastewater treatment facility for the Rio Communities area, located approximately 40 miles south of Albuquerque, has a capacity of over 300,000 gallons per day. Rio Communities Wastewater Superintendent Bobby Towle, explained that the proximity to an industrial area has posed some challenges in the past, “We had a plastic cup manufacturing company delivering chemicals and dyes to the treatment plant; some of the copper from those dyes bound up in our sludge, which affected the sludge permit we had at that time. Another company was delivering a putty-like dye, gumming up our pre-treatment screen augers and requiring us to physically remove the substance with putty knives.” In addition, the organisation needed to find a more effective way to expedite wastewater remediation as currently, extra time and expense are required to keep the treatment systems operable. Drylet analysed the plant’s existing waste sludge production and solids balance, and offered New Mexico Water a trial run of the Aqua Assist. A large, initial dosage was applied in the first week, which was followed by half that dosage the next week, then by a small maintenance dose that has been applied regularly since. “The result was very positive for New Mexico Water, and the plant was able to reduce the amount of wasting as necessary. Towle said, “The product has proven to be very effective overall, as indicated by improved dewatering centrifuge operation, as well as improved sludge management and control of hauling costs. The improved centrifuge operation has resulted in more consistent run times and a commensurate efficiency in polymer application. Drylet allowed us to transition from wasting daily and running the centrifuge weekly to reduce wasting and running the centrifuge less frequently.” Recognitions The effectiveness of Aqua Assist was recognised by the Water Environment Federation (WEF) 2017 last year, when the American wastewater trade organisation granted it the WEF 2017 Innovative Technology Award. “We are honoured to see our technology recognised by WEF as a positive change agent in the wastewater industry,” said Erceg about the win. “We believe the time has come to focus on eliminating biosolids pollution as governments and local communities strive to deploy improved wastewater treatment processes around the world,” he added. In addition, the company won First Prize in the Renewable Energy, Clean Tech, and New Materials ca t ego r y o f t he I nnoSTARS Competition 2017, a platform that connects U.S.-based innovators and companies with Chinese investors, corporates, and strategic partners. Venturing into the Chinese market The power of Aqua Assist and Drylet’s drive for innovation have captured the attention of Nanjing Hoyo Municipal Utilities Investment Administration Group. One of the leading public- private-partnership (PPP) players in municipal utilities markets in China, the Hoyo Group is actively expanding its PPP platform to include innovative technologies as water and wastewater treatment
