The Desal-RO-4040 reverse osmosis membrane is ideal for use in fouling-prone brackish water desalination. This innovative membrane is smoother than a traditional element and offers high impurity rejection for a broader pH range. The smooth design of the RO-4040 requires less maintenance, reduces the operating cost of the system and extends the life of the membrane. This element features male end connections, 31 mil feed spacers, and fiberglass outer wrap.
