4040 Reverse Osmosis Membrane for Seawater Desalination 98.5% Salt Rejection

Hot Selling 4040 Reverse Osmosis Membrane , Suitable For Seawater Desalination

I.Product Description

The reverse osmosis membrane is specially developed for the desalination of medium and high salinity raw water. It has the characteristics of high desalination rate, cleaning resistance and stable operation. The measured desalination rate can reach 99.6% and 99.3%. It is suitable for the desalination treatment of municipal water, groundwater and surface water, and can be widely used in the treatment of boiler feed water, industrial pure water and slightly polluted wastewater.

II.Product Advantages

High Salt Rejection Rate: Under standard testing conditions, the salt rejection rate can reach 99%, with stable performance and superior water quality, meeting higher water use standards.

Scaling Resistance: The unique fluid dynamics design reduces concentration polarization and improves resistance to scaling and fouling.

Specialized Flow Path: The 45-degree diamond-shaped double-layer flow path design improves cleaning and facilitates performance recovery.

Easy Maintenance: The modular design allows for cascading of 1 to 6 units, simplifying cleaning and maintenance.

Small Footprint: High membrane packing density reduces equipment footprint and reduces construction costs.

Easy Maintenance: Fewer seals make maintenance easier, extend service life, and significantly reduce replacement costs.

FAQ

Q1: What type of RO membrane is available in your company?
A1: In general, We have Domestic RO membrane and Industrial RO membrane, For Domestic RO membrane, We have Municipal Tap water RO membrane, Rural Area Under Ground water RO membrane, High-flow Low pressure RO membrane, and Brackish water RO membrane.
For Industrial RO membrane, We have Low Pressure Energy saving RO membrane, BW Brackish water desalination RO membrane, FR Fouling Resistant RO membrane, as well as XLE Extreme Low Pressure RO membrane, and High Salinity Brackish Water Desalination RO membrane.

Q2: What is Salt Rejection Ratio?
A2: The Salt rejection describes the quality of salt removed from the Reverse Osmosis feed water stream as a percentage. It's one of the key element of the RO membrane quality, however, other essential elements such as RO membrane performance durability,stability, application scope in different region, and permeate flow output at the same pressure will all be the important factors to judge the quality of the membrane.

Q3: Is the Salt reaction of the RO membrane the higher the better?
A3: This will be depending on the feed water quality, if the feed water quality is good, even a 90% salt rejection membrane will be workable, if the feed water is with bad quality and with brackish water environment, a higher salt rejection above 95% is an ideal choice. For any membrane that meet the local drinking water standard will be a good membrane.

Q4: Is there are any other element we need to take into consideration when selection the RO membrane?
A4: Yes, the pretreatment filter cartridge and pretreatment system will affect the RO membrane performance as well, please select good quality filters and pretreatment system.

Q5: Why there are white foam-like water being in the treated water at the initial usage?
A5: To preserve the RO membrane for a long shelf-life, and prevent the membrane from being oxidized, a water soluble protection material is coated on the surface of the membrane, which will be rejected in both the rejected water and treated water, for initial use, both rejected water and treated water should be rejected and the the RO membrane should be thoroughly cleansed. The treated water at initial use shall not be injected to the water storage tank.

Q6: Why dry RO membrane has a salt rejection rising process from its initial usage?
A6: The performance of the RO membrane is strictly connected to the wetness of the membrane, when the membrane is wet, it will reach to ts maximum performance, dry membrane has a process to become wet from its initial usage. Make sure that the membrane should be rinsed after each usage.

Q7: Why Active carbon filter is requested for RO membrane?
A7: Chloride and chlorine content is harmful from the feed water, RO membrane is easily to be damaged as the surface of the RO membrane will be easily being oxidized.
