Water treatment is one of the sophisticated chemical processes, which controls the water quality. Turbidity is one among the water quality parameters. This research focuses on the modelling of water treatment process and the development of laboratory based water treatment plant. For developing the model for the water treatment process the three main stages namely, coagulation, flocculation, and sedimentation were considered. Based on the model obtained, a laboratory based water treatment plant was designed and developed. It serves as an experimental setup to carryout coagulation, flocculation and sedimentation processes.
