A METHOD OF OPTIMIZING THE EFFICIENCY OF COAGULATION OF LOW TURBIDITY WATER VIA TREATMENT THEREOF WITH CHEMICAL ADDITIVES WHICH COMPRISES THE SEQUENTIAL STEPS OF FIRST ADDING IN AT LEAST A COAGULATION INDUCING DOSAGE A CHEMICAL ADDITIVE HAVING AT LEAST ONE SITE OF CATIONIC CHARGE TO SAID WATER HAVING SUSPENDED THEREIN 15-30,000 P.P.M. OF SOLIDS, USBJECTING SAID CATIONIC-TREATED WATER TO A ZONE OF TURBULENT FLOW AS DEFINED BY THE PARAMETERS OF THE GRAPH OF THE DRAWING OF POINTS LYING WITHIN AREA A, SUBSEQUENTIALLY FURTHER ADDING A SECOND CHEMICAL ADDITIVE TO SAID PARTIALLY COAGULATED WATER TO COMPLETE SAID COAGULATION, SAID SECOND ADDED CHEMICAL POSSESSNG AT LEAST ONE SITE OF ANIONIC CHARGE, SUBJECTING THE ANIONICTREATED WATER TO A SECOND ZONE OF LAMINAR FLOW AS DEFINED BY THE PARAMETERS OF THE GRAPH OF THE DRAWING OF POINTS LYING WITHIN AREA B, AND SEAPRATING THE THUS COAGUALTED SOLIDS FROM THE WATER.
