The Hydro-Kinetic Green wastewater treatment system from Norweco employs hydrokinetic filtration technology to produce clean, consistent effluent quality. Developed to serve homes and small businesses outside of city sewers, the system uses extended aeration and attached growth processes to treat wastewater, and has nitrification-denitrification technology. Listed by the most stringent wastewater certification in the world, it quietly, efficiently and automatically pretreats, aerates, flow equalizes and filters all wastewater, returning pure effluent back to the environment. All treatment processes are managed by reliable components and user-friendly controls, according to the manufacturer. The integrity of the treatment process is protected by a non-mechanical, demand-use flow equalization device, as well as the Hydro-Kinetic Bio-Film Reactor. 800/667-9326; www.norweco.com.
