The Tannery sector is one of the most important highly water polluting industrial category. India has about 3,000 tanneries with a total processing capacity of 700,000 tons of hides and skins per year. In this paper an attempt is made to know the pollution level in the effluent generated and also suggest advanced treatment system to bring various pollutants like chlorides, COD, BOD and TDS.

This paper attempts to develop a most competent roughing filter combination for low-cost surface water treatment in rural areas by using different parameters of roughing filter such as length of filter, flow condition, filter media, head loss, and velocity.
