Industrial Use RO Membrane-BW Series

Product Description: 

BW series RO membrane is polyamide composite membrane to be used for brackish water desalination. It is featured with low pressure running, high water output and good desalination. It is applicable to the desalination treatment of ground water, underground water and tap water with salt content below 5000ppm.

8” RO membrane is mainly used for pure water and boiler feeding water production in medium to large scaled chemical factory, pharmaceutical factory, food factory, electrical factory and power generation plant, as well as the desalination and purification of municipal used water.

4” RO membrane is mainly used for pure water and ultra-pure water production in small scaled pharmaceutical factory, food factory, electrical factory, as well as the desalination and purification of water supply stations at schools and communities.  

BW series highly contamination resistant RO membrane: Special technology is used to treat membrane surface to increase its hydrophilic property. By that treatment, it reduces sediment of pollutants and salts on membrane surface to achieve contamination resistant effect. It is applicable to the desalination treatment of ground water, underground water and tap water with salt content below 5000ppm. 

8” highly contamination resistant RO membrane is specially suitable for industrial water recycling and industrial waste water and city sewage treatment of medium to large scale.

4” highly contamination resistant RO membrane is specially suitable for industrial water recycling and industrial waste water and city sewage treatment of small scale.

Product Advantages:

Ø Imported raw materials:

The reversed osmosis membrane sheet is purchased from well known membrane component producers in USA and Japan and other key raw materials are all imported from well known foreign manufacturers. By that, product quality and stability are guaranteed.

Ø Advanced production technology:

The membrane component of 8” an 4” spiral wound type is made with most advanced equidifferent spiral wound type technology. It can ensure the produced membrane is of same quality as imported one. The finished product qualification rate has always been kept at above 99.95%, which meets highest standard of the industry and delivered products are ensured to be 100% qualified.

Ø 100% finished product testing for small orders (sampling testing for big orders)

    Each membrane component has passed strict testing before being shipped from factory and we ensure its desalination rate and water production capacity both reach standard and more than standard. For each membrane, there is a unique serial number and testing record corresponding to its specifications. We can provide customer with ex-factory testing report of each membrane.
