EVALUATION OF LOW COST ENVIRONMENT FRIENDLY NATURAL EXTRACTS FOR THE PURIFICATION OF DRINKING WATER

Abstract

About 44% citizens of Pakistan do not have access to safe drinking water. Good quality filters used for the purification of water are out of range for people of remote areas. This study has been conducted to check the efficiencies of different environment friendly materials which are locally available like Rice husk, incomplete burnt rice husk, Wheat husk and Saw dust. Collected materials were passed through pretreatment process like washing, drying and setup developed. Rice husk is burnt under solar concentrators. Samples of drinking water collected from different points from University of Agriculture Faisalabad. The results show that incomplete burnt rice husk is most efficient among all others in controlling different parameters of drinking water like TDS, EC, PH, DO etc. For future it is recommended use rice husk in clay for the formation of filter setup and burns it in kiln. Biological parameters will also be check of drinking water after passing through this setup.
