A COMBINATION OF EFFICIENT, AFFORDABLE & SUSTAINABLE TECHNOLOGY
♦ Terafil water filter, it is an efficient, affordable and sustainable technology filter developed by CSIR, Gov. of India.
♦ Terafil water filter can be used for like dug well, ponds, tubes well and rivers water into clean drinking water.
♦ Function without chemical and electricity.
♦ Core of filter having Capillaries (0.2μm to 0.3μm opening) bridge large pores.
♦ Size of most of pathogens: 1 µm to 50 µm hence most of micro-organisms & turbid particles cannot travel through the ultra-fine capillaries of Terafil filter.
♦ Its effectively removes nearly 99% of turbidity, 95 % of micro-organism, 90-95% soluble iron, also colour and bad odour significantly.
♦ Increases of pH of product water nearly by 1.0
♦ Average turbidity of filter water will be 0.5 to 3 NTU irrespective high turbid raw water (upto 200-300 NTU).
♦ Filter disc is prepared in shape of 50 mm thickness and 100 & 220 mm diameter.
♦ At 250 mm water head and 50 NTU turbidity water filtration rate will be obtained 1-1.5 lit/hr from 100 mm dia. Disc and 4.0 to 8.0 lit/hr from 220 mm dia. Disc.
♦ The filtrate clogs top surface of Terafil over time and reduces flow rate.
♦ Periodic scrubbing and cleaning of top surface of Terafil rejuvenates flow rate.
♦ Core of Terafil never gets clogged, for which long life (up to 5 years) is obtained.
♦ Without sacrificing quality, Rate of filtration can be increases with increases of water head but within limit.
♦ Average bacteria count in product water is almost nil, when normal ground water is filter through “Clay membrane “, while for obtaining pathogen free water from surface water source- mild chlorination (2 mg/lit) is necessary.
