Abstract

The velocity gradient (G-value) and the value of GT are highly correlated to the flocculation efficiency in conventional water treatment process. The determination of G-value is always related to the energy dissipated in flocculation zone. Hydraulic flocculation was established by high speed tangential inlet flow in circular tank with internal cone which give spiral movement of water between the inner surface of the tank and the outer surface of the cone. This work gives an approximate determination of the variation velocity gradient in the flocculation process by calculating the energy dissipated in flocculation on the basis of the head loss through flocculation zone.
