Problem facing by people regarding drinking water is one of major issue and to be rectified. Walnut (Juglans regia) is one of the most important fruit in Pakistan. Pakistan is ranked 24th in production of walnuts in the world, about 2128 tons per annum were generated as a waste This high quantity of walnut shell should be used for some useful work. Apart from this Water contains impurities of dissolved and suspended solids, Calcium bicarbonate, magnesium bi carbonate, magnesium sulfate, calcium sulfate, wastewater discharge, chemical contamination that may be organic or inorganic, fast population growth, use of energy generation of waste from industrial and domestic wastes, corrosion of water pipe lines and industrial waste. Water contains humid and folic acid which gives them a yellowish tinge on this behalf study was made to investigate the low cost bio-coagulant prepared from walnut shell. By utilizing 30mg/l of coagulant dose give a maximum turbidity removal up to 83% and for utilizing 50 μm mesh size turbidity removal up to 82%. Walnut had potential to remove turbidity from water by utilizing different mesh size and pH ranges.
