Presently, in certain applications, three stage of filtration are employed for reducing the feed to 5 micron before feeding into membrane filter. This occupies huge amount of space requiring number of valves, fittings & instruments. Ell Ess Engineering brings to the market for the first time two stage Desal automatic Filter as a single unit, thus covering the three stages in two units. They use advanced RIPBACTM Screen media in both the stages to give the various advantages as stated earlier. As a result the filter occupies very less foot print & due to the unique design the back wash efficiency is quite high to regain the filtration area for giving trouble free operation.
