SYSTEM FOR MIXING INDUSTRIAL WASTE WATER WITHIN A GRAVITY SETTLING TANK

摘要

A system for static mixing in a waste water settling tank to increase the percentage of recovery of entrained solids from the waste water comprising a settling tank having a hopper bottom defining a sludge hopper, a deflector dome centrally disposed within the space contained in the hopper bottom, and an inlet pipe for introduction of waste water containing second entrained solids into the settling tank and having a discharge outlet in proximity to the underside of the deflector dome. Influent waste water is directed vertically upward into the center of the deflector dome which distributes the influent radially into contact, preferably turbulent, with previously introduced waste water containing first entrained solids to cause coalescence of the first and second entrained solids to form larger particles having increased settling velocity.

1. A system for static mixing in a waste water settling tank to increase the percentage of recovery of entrained solids from the waste water, comprising:
a) a settling tank having a hopper bottom defining a sludge hopper; b) a deflector dome disposed within the space contained in said hopper bottom; and c) an inlet pipe for introduction of waste water into said settling tank, said inlet pipe having a discharge outlet in proximity to the underside of said deflector dome.
