Water Purification by Double Filtration Using Ceramic Filters

Abstract

This paper presents the results of an experimental study on the effects of double filtration on the rate of water percolation and E. coli removal efficiency of ceramic water filters made from mixtures of different ratios of clay powder, fine sawdust and powder of grog. The results show that double filtration produces superior quality of filtered water compared to single filtration although the rate of water percolation is higher for single filtration.
