Applications in desalination and water reuse plants for the same or alternate applications e.g. wastewater reuse, brackish water reverse osmosis, grey water treatment etc.
We have converted the discarded membranes into useful membranes for following applications:
- Low salinity brackish water desalination/wastewater treatment and reuse
- Partial substitution of the original application by enhancing the flow rate but maintaining the salt rejection performance
- Conversion to ultrafiltration-like membrane elements by removal of polyamide barrier layer
The second life of membrane will be a “waste to wealth” proposition.
(Pilot plant scale development and demonstration)
The technology is ready for technology transfer and can be implemented on commercial scale. The industry-specific customization may be required.
It is very important from environment perspective to extend the life cycle of membrane elements since membrane waste is a hazardous polymeric waste. Thus, it renders environment-friendly proposition. The treatment chemicals are neutralized before disposal.
Not yet licensed; Discussions with industries are on with customer field trials
Chemicals, alcohol, acid, surfactants
Pumps, membrane test-rig, reactor, piping system, tanks etc.
The rejuvenated membrane cost will be about 15-20% of new membrane cost. It depends on the degree of fouling of membrane and desired use as the second life of membrane.
Depends on the scale; Will be available on request
