“The State Government may consider setting up a series of common effluent treatment plants. Our target would not only be to treat effluent water but also make it fit for reuse.”

Vadodara-based Permionics Membranes, a technology provider for industrial water purification, has evinced interest in participating in the Tamil Nadu Government's initiative on effluent treatment for dyeing units in Tirupur.
Mr V.Y. Jose, Director, Permionics, said the company has already provided water treatment systems, using proprietary HPA-NF (hydrophilisation amide nano filtration) and HPA-RO (hydrophilisation amide reverse osmosis) membranes, to over 40 per cent of the dyeing units at Tirupur.
The Union Budget has allocated a one-time grant of Rs 200 crore to the Tamil Nadu for installation of a zero liquid discharge system there. A membrane is a layer of material which serves as a selective barrier between two phases and remains impermeable to specific particles, molecules, or substances when exposed to the action of a driving force.
“The State Government may consider setting up a series of common effluent treatment plants. Our target would not only be to treat effluent water but also make it fit for reuse,” he said.
Permionics has indigenously developed a HPA-NF membrane system which gives significant energy saving by reutilising dye-bath brine.
The permeate recovered from the HPA-NF process contains salt and is suitable for reuse.
“A typical dyeing unit in Tirupur uses about 100 water tankers a day which has come down to five a day after we installed our system,” said Mr Jose.
Permionics has also bagged orders from the Defence Laboratory, Jodhpur, for seven units of mobile nuclear, biological and chemical (NBC) water purification systems.
The mobile unit is fitted on to 5/7.5-tonne vehicle and is powered by a self-supporting 15-kVA generator. The system includes pre- and post-treatment equipment.
The unit uses a semi-automatic control system to ensure minimum maintenance, can produce 2,000 to 3,000 litres of potable water an hour from NBC contaminated brackish water.
“The reverse osmosis membrane-based mobile NBC water purification system, including the power genset adheres to the JSS 55555 specifications and has met the needs of Indian Army,” said Mr Jose.Related Stories:
