TERAFIL Water Filtration system

Advantages / Salient Technical Features
• The technology can efficiently remove excess iron &
turbidity from drinking water.
• Turbidity removal : > 99 %
• Iron removal : 90-95 %
• Life cycle : > 03 Years
• Low operation cost : 03 paisa/ liter
• Filtration capacity : 50-100000 LPD Zero water
wastage
• Electricity not required for its operation.
• User friendly.

Problem being addressed
• Drinking water is contaminated with excess iron &
turbidity in many region of our country. For rural
and semi-urban sectors, there is no such affordable
water purification technology for treatment of iron
& turbid water. The technologies available for iron
removal are not cost effective to install and operate.
TERAFIL Technology developed at IMMT for efficient
removal of Iron & Turbidity is cost effective, electricity
independent, easy to operate, environment friendly
etc.
