It goes without saying, with challenging feed water conditions, higher and higher emphasis are now put on designing and qualifying pre-treatment systems. The focus hence has shifted from the terminal stages of purified and WFI generation to the starting stages of pretreatment.
Pretreatment systems are designed for removal of Physico-chemical impurities & antimicrobial treatment solutions from the incoming water. These typically comprise of following unit processes
