Modelling and Construction of Acoagulation/Flocculation Tank for NDA Permanent Site

A Flocculation system for water treatment facilities comprises of a flocculation tank having a plurality of baffle which divide the interior of the flocculation tank into a plurality of components. The baffle are arranged to provide inter compartmental openings between adjacent upstream and downstream compartment, which in turn are arranged to provide a serpentine flow path through the flocculation tank. A mechanical mixer is mounted in each compartment for supplementing the mixing energy provided by the serpentine flow, particularly during period of low water flow rates. The aim of this research work is to construct a model of a flocculation tank capable of contributing in the water treatment process to provide domestic water supply for NDA permanent site. The objective of construction of coagulation /flocculation chamber is to produce a settled water of low turbidity which in turn will allow reasonably long filter run using suitable coagulants type and required amount or dosage and achieving an effective floc formation.
