DC Water has awarded a contract to Kruger Inc., part of resource management group Veolia, for a major new installation of the company’s ACTIFLO technology to process and treat wet weather flows, according to a press release.
Under the terms of the deal Kruger will implement three 83 MGD (millions of gallons per day) ACTIFLO trains at the Blue Plains Advanced Wastewater Treatment Plant in southwest D.C., giving a total treatment capacity of 250 MGD. This installation will be the largest ever designed for ACTIFLO technology in the United States, Veolia said in the release.
The new system will help the water company treat significant volumes of rainwater, and can be expanded in the future, stated the release. The project design takes into consideration a total treatment capacity of 500 MGD, which would be accomplished by installing three more ACTIFLO trains.
ACTIFLO is a high rate water clarification process which has been used for municipal and industrial water and wastewater treatment for more than 20 years. As part of an expansion at Blue Plains, excess wet weather flow will be pumped through screening and grit removal from a newly constructed tunnel, then to the ACTIFLO process.
The system is expected to be fully operational in 2018, reported the release.
According to Kruger, a Veolia business unit that specializes in water treatment solutions for municipalities, the ACTIFLO process has exceptional solids removal capabilities and can be utilized in any wastewater application that needs solids separation, including phosphorus removal and water reuse as well as treating wet weather flows.
