A REVIEW FOR : DESIGN OF DUAL MEDIA WATER FILTER PURIFIER USING CLAY POT

Abstract

Low cost water treatment devices for rural households like filters, RO and UV based water purifiers are developed by many industries but these devices suffer from problems like filter clogging, periodic replacement of filters, wastage of water (in case of RO) and unavailability of electricity in rural areas making them costlier. Due to above reason RO, UV purifier are not affordable to rural areas. The objective of my project is to deal with improvisation in existing filter design and remove the flaws in existing filtration models at economical level. The study deals with the purification of water using naturally available material using copper mesh as a disinfectant, coconut shells as filter media and provide effective and economical water purifier for rural area. Earthen pots will used for the purification of water made from different proportions of Clay and Saw dust (50:50, 60:40, 70:30). Lake and well water will be treated as it is normally used in rural areas. Various drinking water test will carried on samples before and after the treatment of water. As per the study of various research papers showed that the filters were capable to treat water as per the drinking water standards. Maximum turbidity and TDS remove.. As copper used as a disinfectant in this case, less chances to trace of E-coli found in the treated water. After completion of over all experiment clay purifier can be effectively used as a low cost filtration device in rural areas.
