4 Inch RO Membranes

  • MDC Water carries 4 inch 4040 membrane in a wide variety of types to suit most applications including brackish water, seawater, low and ultra low pressure membranes.
  • We only work with trusted reverse osmosis membranes manufacturers:
    • LANXESS (Germany): LANXESS has designed Lewabrane® RO membranes for state-of-the-art desalination of seawater, brackish waters, and low-salinity waters in industrial and potable water applications. Lewabrane Reverse Osmosis membrane elements are produced in a modern, fully automated, state-of-the-art production facility in Bitterfeld (Germany).
    • DOW Filmtec (USA): The world leader in producing elements to demineralize brackish water, desalinate seawater and more. DOW Filmtec produces the most widely used RO and NF technologies in the world—trusted by municipalities, manufacturers of all types, small businesses and families wanting clean, healthy water.

4 Inch Brackish Water Reverse Osmosis Membranes

Our brackish water RO 4040 Membranes provide high permeate flows and salt rejection at high salinity inlet water (up to 8,000 ppm NaCl Salinity).
Brackish water RO Membranes are the best balance of flow and salt rejection.

Low Pressure Reverse Osmosis 4 Inch Membranes

Low Energy (LE type) and Low Pressure (LP) membrane elements are recommended for low-moderate salinity applications or/and in applications where low energy consumption is an important consideration.

The LE and LP elements are designed with a highly efficient polyamide membrane barrier layer, providing high flow productivity combined with excellent salt rejection.

Lanxess LE and Vontron ULP membrane elements are based on 150 PSI (10.3 bar) test working pressure.

 

Ultra Low Pressure Reverse Osmosis 4 Inch Membranes (Extreme Low Pressure)

They are designed for low salinity water to operate at ultra low pressure (ULP). The high permeability results in up to 40% lower energy consumption compared to standard elements.

Lanxess ULP and Vontron XLP membrane elements are based around 100-110 PSI (around 7 bar) test working pressure.

Seawater Desalination 4 Inch RO Membranes

  • Used for Seawater desalination systems.
  • Marine and Maritime watermakers.
  • Yacht and boat desalination units.
