Abstract

A high efficiency filter medium is placed in series with a water treatment clarification system for receiving the treated effluent discharged from the clarifier. The treated water is passed through the high-efficiency filter media for reducing the suspended solid constituent of the water to less than 10 ppm. The filter is supported in a open mesh carrier tray and is made of a polyester material adapted for collecting and entrapping the solid suspended particles in the clarified water discharge.
