Abstract
A mechanism for wastewater treatment which includes a plurality of solids settling chambers, at least a primary, secondary and a tertiary filter for selectively filtering waste-water and effecting settling of solids of different sizes in the settling chambers and flow equalization ports for effecting demand flow of wastewater through the mechanism and the eventual discharge of high quality effluent. Chlorination and optionally dechlorination are effected as integral process functions of the wastewater treatment mechanism.
