Terafil Water Filter

TERAFIL WATER FILTER is a low cost device to filter impure water into clean drinking water. The filter is developed to cater the needs for clean drinking water, especially when the water is rich in sediments, suspended particles, iron and certain microorganisms causing water borne diseases. It is most suitable for areas where water from both surface and ground water sources like dug wells, ponds, tube wells and rivers, is used for drinking purpose.

Features of technology:

TERAFIL(TM) is a burnt red clay porous media used for filtration and treatment of raw water into clean drinking water. ‘TERAFIL’ is produced from a mixture of red clay (silt clay), river sand and wood saw dust, without using chemicals. The dough of the mixture of these materials is sintered at high temperature in a low cost coal/wood fired furnace to make the terracotta disc porous. During sintering process, the wood particles are burnt and clay particles are sintered around the sand particles leaving elliptical/circular large size pores in between.
