Title of Process/ Know-how/ Product/Design/Equipment
Antifouling ultrafiltration membrane for separation of oil-in water emulsion
Application/Uses/Problem being addressed
Separation of oil-in water emulsion and removal of pathogens under low applied pressure (5 psi)
Salient Technical Features including Competing Features/ Impact
Antifouling ultrafiltration membrane can separate oil-in water emulsion such as soybean oil-in-water (>99%) and hexadecane-in-water emulsion (>40 nm to 20 micron droplet size) under low applied pressure (5 psi) and can be regenerated by washing with water.
TRL Level & Scale of Development:
-
Business scope & opportunity (in terms of scale, cost, market etc.):
Water containing emulsified oil (bout 0.5-1%) could be separated under low applied pressure for further treatment with other membrane depending on feed composition. The process is scalable. Cost of per m2 membrane=Rs. 600-700 (approximate)
Environmental Considerations:
Generation of water containing DMF
