The brackish water filter consisted of filtering media like sand, gravel, grit, charcoal, broken brick, gypsum, sponge and sawdust. The effective depths for sand, gravel, grit, charcoal, gypsum, broken bricks and sawdust were found to be 45 cm, 30 cm, 15 cm, 15 cm, 7.5 cm, 15 cm and 30 cm, respectively. It was observed that EC and pH of untreated brackish water was reduced after filtration. The EC of brackish water was 41.7 dS/m which was reduced to 35.9 dS/m with a per cent reduction of 13.90%; while pH was 7.89 which was further reduced to 7.23 with per cent reduction of 8.36%. The total cost of newly developed brackish water filter was found to be Rs. 623. Filtered brackish water was in permissible limits for irrigation after treatment. It was also predicted that this filter can also be used for filtration of sea water.
