The West African City of Abidjan in Côte d’Ivoire has historically provided drinking water to its five million residents from water treatment plants that use hydrated lime systems. But because of the high content of carbon dioxide in the local groundwater, up to 160 ppm, setting the water to calcium carbonate equilibrium using hydrated lime was economically, operationally and environmentally challenging for the city of Abidjan.
Since opening in 1930, the Bachman Water Treatment Plant in Dallas has increased its processing capacity from 30 million gallons per day to 150 million gallons per day, with the latest upgrade in 2007.
The AnoxKaldnes™ MBBR (Moving Bed Biofilm Reactor) process is a biological wastewater treatment process that utilizes specialized plastic carriers to create a surface on which a biofilm can attach.
Clearas Water Recovery's patented treatment platform, Advanced Biological Nutrient Recovery (ABNR) technology, is highly modular and scalable, providing a sustainable approach to cleaning water. The Clearas system consists of three core phases: the blend phase, the nutrients recovery phase and the separation phase. For optimal results, Clearas has partnered with Endress+Hauser for dependable products and reliable technical expertise.
Previously the crew at Payson WWTP wrestled with clogs that required constant attention and increased system downtimes. With the installation of the new headworks, the comparison was stark because suddenly the flow from the headworks was debris-free.
Spanish Fork WWTP utilizes the STEPSCREEN® in two identical headworks systems. The technology upgrade has made a vast difference in plant processing. Prior to the implementation of new technology, only one channel was processed.
As part of the new facility for the City of Clinton, the plant installed a new finescreen as an integral part of the operations. What they discovered was not only a reliable and durable technology but the automated feature of the system was transformational for plant operations. Read what they have to say.
How do I remove screenings from my sludge? Even when screens are installed at the head of a treatment facility, debris always ends up in the sludge. Plastic parts and fibrous materials can cripple operation of important downstream technologies.
Sun City, AZ, has had the same wastewater treatment plant since the '70s, along with a new, expensive problem: non-dispersible waste.
Pump blockages and rags are a significant barrier to energy and operational efficiencies at pump stations, causing unscheduled shut downs, safety hazards for operators, costly equipment repairs and increased power usage due to a decrease in the pumps’ hydraulic performance. Scottish Water observed these negative effects caused by an influx of wipes and rags throughout a network of area pump stations. Engineers looked to a proven, powerful solution in the form of two JWC Environmental Channel Monster® grinders at one of their most problematic sites.
The Coeur D’Alene, ID, wastewater treatment plant was having continual problems with two sludge macerators, in part because of the durability of the macerator.
