Abstract

Abstract: Water in urban areas and especially in developing countries is being polluted due to various reasons. Few of the pollution are due to disposal of industrial effluents directly into rivers, improper treatment of waste water and infiltration in waste disposal sites. The primary reason for contamination near dump yards which do not have proper lining material is due to infiltration. This poses a huge threat to the people living near the dump yard sites. In this paper we report a novel membrane developed using PVC and PVA for filtration of water in which PVA partially acts as a sacrificing component in the creation of pores. The porosity of the polymer composite membrane was studied using scanning electron microscope. The contaminations due to Vamanjoor dump yard site located near Mangalore, Karnataka, India are investigated and the various pollutants in the ground water are identified. A composite filter membrane unit is designed and developed which is used as an integral part of the filtration unit for the purification of water obtained from the areas surrounding the above dump yard. This filtration unit is able to reduce the contamination significantly making the filtered water fit for human consumption. The high quality of filtered water coupled with its low cost are expected to be of significant benefit to society.
