procedure for Reverse osmosis in brief explanation
Not sure I understand your question, can you be more specific? What kind of 'material' do you need for RO for the pharmaceutical industry?
In Pharmaceutical, what kind of water are you looking into ? USP purified water, Water for injection (WFI), USP bacteriostatic water for injection or laboratory waters ?
Depending upon the water quality, its required TDS and pH you can get an RO water purifier system built. You will also have to look into UV water sterilizer.
