AbstractWater treatment plants traditionally use coagulation/flocculation process to remove organics and turbidity particles in drinking water. As a result of the chemical optimisation of the coagulation process having such a strong influence, it is believed that the current hydraulic conditions for flocculation cited under best practice could be out of date. A 450 Mld plant treating upland water was chemically optimised, and it was observed that the total mixing energy input could be reduced by 66% without any detrimental impact upon the clarified water being observed. Under the new mixing regime, energy costs could be reduced by £37 300 pa equating to approximately a 280 t reduction in CO
