It has higher rejection uses less energy and resists foulants in challenging waters. It is the best choice if you are dealing with controlled pre-treatment waters and seeking consistent, high performance, long element life, and increased productivity.AdvantagesDecades of proven performanceDelivers high quality permeate waterOffers the most effective cleaning performance, robustness, and durability due to its widest cleaning pH range (1 13) tolerance and the support of Dow technical representatives high rejection gives good water qualityOperation GuidelinesAvoid any abrupt pressure or cross-flow variations on the spiral elements during start-up, shutdown, cleaning, or other sequences to prevent possible membrane damage. During start-up, a gradual change from a standstill to an operating state is recommended as follows:Feed pressure should be increased gradually over a 30-60 second time frame.Cross-flow velocity at the set operating point should be achieved gradually over 15-20 seconds.Permeate obtained from the first hour of operation should be discarded.
