FAQs on Reverse Osmosis RO membrane OEM manufacturing
Q1: What type of RO membrane is avaliable in your company?
A1: In general, Hikins has Domestic RO membrane and Industrial RO membrane, For Domestic RO membrane, Hikins has 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, Hikins has Low Pressure Engergy 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 reation 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 pre-treatment filter cartridge and pre-treatment system will affect the RO membrane performance as well, please
select good quality filters and pre-treatment 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 oxydized, 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 thourghly cleansed. The
treated water at initial use shall not be injected to the water storage tank.
Q6: Why there are bublles in the treated water?
A6: Oxygen and Nitrogensand carbon dioxide is water soluble in the molecular form, during the water filtration process in the
Reverse Osmosis process, those air will be released due to the pressure change between input water and output water. Those air is
not harmful, just like Coca-cola.
Q7: Why dry RO membrane has a salt rejection rising process from its initial usage?
A7: The performance of the RO membrane is strictly conencted 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
hsould be rinsed after each usage.
Q8: Why Active carbon filter is requested for RO membrane?
A8: 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 oxydized.
