Vontron reverse osmosis membrane SW21-4040. It is mainly used for producing various scales of bottle water, drinking water, industrial used pure water, high purity water, boiler replenishment water, also for wastewater reuse, material concentration, purification and refining purposes. The 4040 Brackish Water RO Membranes are meant for the desalination of brackish (salty) water with high TDS / Mineral content. These membranes are characterized by low-pressure operation, high water productivity, and excellent desalting performance.
