High Pressure Disc Water Treatment Filter For River / Underground Water
Water Treatment Filter Introduction
The Water Treatment Filter has the outstanding advantages of distinguishing common screens type self-cleaning filter. AR filter has the precision range being 30-2000 microns. It utilizes extremely rugged V-shaped wadge net filter screen with high surface gap accuracy. Stand- alone machine has very large filter area, fine filtration on low surface flow rate. Single filter super large flow rate is 8000m3/h. Owning very high reliability, it can be competent for the worse water quality, such as oily sludge-like impurities, soft viscous impurities, high impurity content, a small amount of hair and fibrous impurities.
