Wastewater decanter DynaCanter™

Parkson offers two options for liquid removal from water and wastewater basins: effluent and supernatant decanters. The Parkson DynaCanter™ is a floating style decanter used to remove treated effluent or supernatant from the upper portion of the basin. The decanter utilizes a flex joint to allow vertical articulation as water levels move between high and low water levels. The decanter collects water from below the surface to preclude foam, scum, or other floatables from the effluent. A standard open / close valve is used in the effluent piping to control flow rate through the decanter. No electro-mechanical components are used inside the basin making operation and maintenance convenient for the operator. For the Effluent style decanter a series of check valves are provided in the decanter draw tube to isolate the effluent piping from the mixed liquor during mixing and aeration steps, and thus ensuring clear effluent being removed from the basin. In the Supernatant design the plugs are replaced with machined orifices and the piping is turned upward to allow removal of liquid closer to the surface.
