Reverse Osmosis RO Membrane Element
Reverse Osmosis RO membrane elements are an aromatic polyamide composite membrane element developed for reverse osmosis system. RO membranes suitable for different water quality, while saving energy, RO membrane elements can guarantee the quality of the water produced and improve the efficiency. RO elements have the characteristics of high desalination rate, large flux, long service life and economic cost, saving the cost of reverse osmosis water treatment system. International common sizes, direct replacement of RO membranes of worldwide major brands. Reverse osmosis membrane elements are widely used in brackish water filtration, seawater desalination, industrial wastewater reuse, food and beverage, power plant boiler make-up water, pure water equipment, chemical RO filtration, surface water reuse, textile printing and dyeing industry etc.

Brackish Water Reverse Osmosis RO Membrane Element
Brackish Water Reverse Osmosis (BWRO) membrane elements are used in many applications, including electronics, power, petrochemical, refinery, food, and beverage industries, where high dissolved solids rejection at low pressure are critical.
With high rejection and durability, BWRO membrane elements treat over 60 million m3/day of water worldwide. RO membranes (available in 2.5 inch, 4 inch and 8-inch diameters) are used for municipal, industrial, and commercial applications.

Sea Water Desalination Membrane Element
Reverse osmosis membranes for seawater applications are an innovative technology enabling the desalination of seawater to be aordable for both industrial and municipal use. Seawater Reverse
Osmosis (SWRO) can cut the operating cost by more than 25% compared to the previous seawater desalination technologies (such as distillation). SWRO also contributes to CO2 reduction in the plants.
We manufacture seawater RO membranes in 2.5 inch, 4 inch and 8 inch diameters that can treat seawater or high salinity water sources with > 10,000 ppm. Our products are widely used for mega desalination plants, watermakers for private boats and commercial ships, and treating mining tailing water for reuse or discharge.

Nanofiltration Membrane Element
Nanofiltration (NF) is a membrane liquid-separation technology sharing many characteristics with reverse osmosis (RO). Unlike RO, which has high rejection of virtually all dissolved solutes, NF provides high rejection of multivalent ions, such as calcium, and low rejection of monovalent ions, such as chloride.
Nanofiltration membranes come in three different sizes (2.5", 4", and 8"), with each being specifically ideal for various applications. The most common utilizations for these membranes are groundwater and surface water, where the removal of organics is done through partial softening in order to ensure a degree of hardness and water quality. The high active area membrane coupled with low net membrane driving pressure permits these impurities to be extracted at low operating pressure.
