‘TERAFIL’- Red clay filtration media (disc)�TERAFIL – Burnt porous red clay media (disc),

used for filtration and treatment of both surface

& ground raw water into clean drinking water.

�Materials of TERAFIL: Red clay (pottery clay),

sand, wood saw dust

For treatment of ground water:-

Quality of product water:-�Turbidity : Within BIS limits

�Bacteria : Within BIS limits

�Iron : Within BIS limits

TERAFIL- water filter disc

�Iron : Within BIS limits�pH : Within BIS limits

�Color & odor reduces drastically�Cost of product water: Rs.2/- per ton

�Life of Terafil filtration disc: 5 years�Life of Terafil stand-alone plant: 10 yr.

For treatment of surface water:-Mild chlorination (0.01gm/ltr. product water)necessary to get pathogen free product water.Nano-silver coating on Terafil disc: at ARCI & IMMT

Capacity: 1 to 1,00,000 lit/day
