Abstract
Described herein is a device for the treatment of water and wastewater that provides a biological or chemical reactor a means to enhance performance by initiating a unique flow pattern between the reactive and solids/liquid separation zones. Said device circulates water between the two zones by forcibly directing water that enters the settling zone back toward the reaction zone via an opening in a partition. The fluid motion scours the bottom of the settling chamber to prevent the accumulation of biologically active solids while maximizing the time those solids spend in the reaction zone; thereby increasing the treatment efficiency of the overall process.
