Title of Process/ Know-how/ Product/Design/Equipment
Hollow fibre domestic water filter of 1 LPM capacity operated under gravity without any electrical energy
Application/Uses/Problem being addressed
Water purification
Salient Technical Features including Competing Features/ Impact
The unit is based on indigenously developed hollow fibre (HF) membranes of MWCO 90 – 100 kDa. The HF module is preceded by one micron and carbon filter to remove the suspended particles, odour and colour (if any) from the feed water. The filter equipped with a water level sensor works under gravitation (7 – 8 psi) without any electrical energy input. The HF exhibited > 6 log reduction in Bacteria and needs simple backwash with water for every 1.5 months for disinfection of supply tap water.
