ABSTRACT:
A single, integrally formed tank has an upper portion of a rectangular configuration and a lower portion of downwardly decreasing volume and defined by a plurality of exterior walls, at least two of which are inclined downwardly and inwardly toward each other. The interior of the tank is divided into three serially connected compartments by means of interior walls which are inclined in directions substantially parallel to one of the inclined exterior walls. The compartments thus formed are a first, neutralization and coagulation compartment, a second, flocculation compartment, and a third, lamellar decanting and sludge settling compartment. Within the flocculation compartment are arranged a plurality of spaced inclined plates defining upwardly inclined flow passages into which extend deflectors to create eddy currents in the water passing upwardly through the flocculation compartment. Within the decanting compartment are arranged a plurality of inclined hollow tubes which facilitate downward settling of sludge and upward movement of the decanted water.
