Technology for the manufacturing thin-film composite reverse osmosis membrane for desalination and water purification
Desalination membranes are envisaged as a solution to increasing freshwater scarcity and an indigenous product ensures demand and supply end with greater certainties and still at an affordable and competitive market price. Spiral modules of 4040 and 8040 size using the TFC modules can be utilized for brackish/seawater desalination for small to large scale applications. There is a large scope for scale-up facilities to meet the growing safe water needs of the country, as at present all the desalination plants in the country are based on the imported membranes modules.
Technology package consists of the conditions for making ultrafiltration membrane and thin-film composite membrane; manufacturing of different size (1212, 4040, 8040 sizes) spiral modules raw material requirement; design of the machinery
