Design Of Dual Media Water Filter Purifier Using Clay Pot

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 our 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 and provide effective and economical water purifier for rural area. Earthen pots are 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 was treated as it is normally used in rural areas. Various drinking water test carried on samples before and after the treatment of water showed that the filters were capable to treat water as per the drinking water standards. Maximum turbidity and TDS was removed in 1st model (50:50) up to 89% and 72.35% respectively for lake water and 78% and 67.47% respectively for well water As copper was used as a disinfectant, no trace of E-coli was found in the treated water for all three models. The results showed that Pot Filter (50:50 model) can be effectively used as a low cost filtration device in rural areas.
