Using Jet Mixing Techniques to Enhance Direct Filtteration

Abstract

The present study investigates the effect of jet mixing techniques performed with two types of coagulants (Aluminum sulfate hydrate [Al 2 (SO 4 ) 3 .16H 2 O] and Magnesium chloride MgCl 2 ) using the polyacrylamide PAM (C 3 H 5 ) n as flocculent aid, on the flocculation. The study include two parts, the first one is the numerical analysis using ANSYS Fluent and CFX program. The second part included the experimental work in which Kaolin particles used to simulate the suspensions in natural resource water. The results indicated that the mixing process using jet mixing tank system produce uniform semi spherical shape. The image analysis provided indications that the floc with manganese chloride are compacted and dense so that it can be more suitable for direct filtration procedure.
