Basic Info.

Product Description

Product Name: Household RO membrane 50/75/100/200/400 GPD

25PCS/CTN, 32*32*34CM, 7KGS/CTN

Installation Instructions

-Unscrew the nut on the membrane shell cover at the inlet water connection end, take out the inlet water pipe, then use the membrane shell wrench to lose the membrane shell cover.
-Take the RO membrane from its packaging, put the end of the membrane with 2 O-rings into the RO membrane shell (See The following Diagram ) and push it in,
- finally, screw the membrane shell cover back on, tighten it with a membrane shell wrench, put the inlet water pipe back into the inlet water connector and screw the nut tightly, then push the membrane shell card into the large single clip.

Direction For Use

1. When installing the RO membrane, you should pay attention to the direction of the membrane;

2. When installing the RO membrane, you should first make sure that one end of the membrane has 2 O-rings;

3. When installing, be sure to put the end with the O-ring into the end of the membrane shell with the pure water connection, for correct installation you need only a little force to put the RO membrane into the membrane shell, if you encounter too much resistance, please do not force the membrane into the shell, or it could lead to permanent damage to the membrane shell or membrane components (the membrane manufacturer does not take the responsibility for replacing components due to damage made during installation);

4. Damage to the membrane shell and membrane element caused under the above-mentioned situation is not covered by the warranty.

A. Full range RO membranes 50GPD to 1000GPD for home use.B. Self-produced membrane sheet.C. Each roll of membrane sheet will be tested before bulk production.D. Each finished membrane will need pass vacuum testing, to make sure salt rejection rate.E. OEM and ODM orders are welcomed.

FAQs on Reverse Osmosis RO membrane OEM manufacturing
Q1: What type of RO membrane is available in your company?
A1: In general, We have a Domestic RO membrane and an Industrial RO membrane. For the Domestic RO membrane, We have a Municipal Tap water RO membrane, Rural Area Under Groundwater RO membrane, a High-flow Low-pressure RO membrane, and a Brackishwater RO membrane. For the Industrial RO membrane, We have a 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 the 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 elements of the RO membrane quality, however, other essential elements such as RO membrane performance durability, stability, application scope in different regions, 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 creation 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 of bad quality and with a brackish water environment, a higher salt rejection above 95% is an ideal choice. Any membrane that meets the local drinking water standard will be a good membrane.
Q4: Is there are any other elements we need to take into consideration when selecting 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 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 RO membrane should be thoroughly cleansed. The treated water at initial use shall not be injected into the water storage tank.
Q6: Why there are bubbles in the treated water?
A6: Oxygen Nitrogen and carbon dioxide are 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. That 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 connected to the wetness of the membrane, when the membrane is wet, it will reach to its 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.
Q8: Why Active carbon filter is requested for the RO membrane?
A8: Chloride and chlorine content are harmful from the feed water, RO membrane is easy to be damaged as the surface of the RO membrane will be easily oxidized.
