A Comparative Study of hand operated Water Purifier

Abstract

Abstract The present work shows the comparative analysis of various designs of portable water purifier without consuming electric power. Four different combinations of reverse-osmosis membrane, alum, potassium permanganate, sodium tri chlor has been used for obtaining optimized value of total dissolved solids (TDS) of the known sample of water. In the subsequent stages of the project the various components of the product will be designed and fabricated. The quality of the water filtered by the prototype device depends upon the membrane (filter) it is using so the proper designing and selection of the filter is also a very crucial task. The specialty of the product is that it is a compact product hence can be easily carried to anywhere. Its operation is very easy so it can be operated by anyone with ease.
