Abstract
A system and method for the treatment of wastewater. In one aspect, the invention can be a method of treating wastewater comprising: a) introducing wastewater having a first turbidity level into a wastewater treatment system; b) injecting an aqueous polymer mixture into the wastewater to flocculate suspended solids within the wastewater; c) removing the flocculated suspended solids from the wastewater to form a treated water having a second turbidity, the second turbidity being lower than the first turbidity; and wherein the aqueous polymer mixture of step b) is formed by introducing a raw polymer into a re-circulated portion of the treated water.
