Application of Tube Settlers in Water Treatment Process—A Review

Water is a basic need of human being and requires at every level of life. The widespread importance to the treatment of water is given by many researchers and scientists. But as the advancement in human life and processes because of increase in population, good quality of water requires at every hour of day. Water should meet the desired standards governs by the regulatory agencies and can fulfill the demand. The demand of water for the masses can be provided with the help of advance techniques. The treatment process involves various operations in water treatment plant out of which sedimentation plays very much vital role of removal of solids present in water. The removal of colloidal particles with high rate can be achieved through high rate settling after application of lamella settlers & tube settlers in settling tank. A system of lamella or tube settlers is a feasible solution for drinking water treatment process to increase treatment capacity within small duration. Further it reduces load on treatment units & improves effluent water quality and decrease operating costs at optimum level. Tube settler modules are available in various sizes which can fit on any tank size according to requirement and required designed length of tubes allow varied rate of flows. Year by year, advancement incorporated in the module & simultaneously addition in the extensive knowledge of the water treatment process is done. This paper emphasizes on the work which is carried out & the basic application, advancement in lamella & tube settlers done by various researchers.
