Rejuvenation of the end-of-life seawater reverse osmosis membrane elements
IPR Status & Details:
Under filing
Application/Uses/Problem being addressed
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.
Salient Technical Features including Competing Features/ Impact
We have converted the discarded membranes into useful membranes for following applications:
The second life of membrane will be a “waste to wealth” proposition.
TRL Level & Scale of Development:- TRL 5 TRL Reference
(Pilot plant scale development and demonstration)
Business scope & opportunity (in terms of scale, cost, market etc.)
The technology is ready for technology transfer and can be implemented on commercial scale. The industry-specific customization may be required.
Environmental Considerations
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.
Status of Licensing:
Not yet licensed
Not yet licensed; Discussions with industries are on with customer field trials
Status of Commercialization:
Not applicable
Major Raw Materials Needed
Chemicals, alcohol, acid, surfactants
Major Plant Equipment and Machinery Required
Pumps, membrane test-rig, reactor, piping system, tanks etc.
Techno-Economics
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.
Technology Package
Depends on the scale; Will be available on request
