Seawater 4040 Dry Type 400G Reverse Osmosis Membrane
Product description:
The universal reverse osmosis membranes series products are
suitable for the deep treatment,such as desalting and chroma
purification from surface water, ground water, river water, lake
water and tap water etc.
It can effectively remove various organic compounds such as salt,
insecticide, herbicide, and THM precursor, bacteria and viruses.
It is widely used in various application fields such as chemical
process water, drinking water and boiler make-up water of various
scales, which can bring significant cost-effectiveness and high
salt removal effect to customers.

FAQs on Reverse Osmosis RO membrane OEM manufacturing
Q1: What type of RO membrane is avaliable in your company?
A1: In general, MR has Domestic RO membrane and Industrial RO
membrane, For Domestic RO membrane, MR 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 MR 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.
