Abstract
A system and method for static mixing in a waste water settling tank to increase recovery of first entrained solids and solvated materials, comprising a settling tank having a recirculation ring and a hopper bottom defining a sludge hopper having a flat bottom portion, a fluid containment assembly, and a fluid deflector assembly with an optional fluid dispersion assembly. The system further comprises an inlet pipe for introduction of waste water containing second entrained solids and solvated materials into the settling tank and a discharge outlet in proximity to the underside of the fluid deflector assembly with nozzle facing downward. Influent waste water is directed both downward into the fluid containment assembly and upward into the center of the fluid deflector assembly and an optional fluid dispersion assembly to distribute the influent into contact with previously introduced waste water to cause coalescence of the first and second entrained solids.
