Domestic TW-1812-75GPD Reverse Osmosis Brackish Water Purifier Parts RO Membrane
Chlorine damage to the membrane can lead to lower salt rejection and poor-quality permeate, which in turn could result in costly membrane replacement and down-time. If chlorine is present in the feed water, it is common practice to neutralize it with a sodium sulfite solution, a carbon bed, or combination of the two.RO membrane cleaning should be performed with high and low pH CIP chemicals. The high pH cleaning should always be performed first to penetrate and disperse biological or organic foulants.
Advantages of our household reverse osmosis membrane:
1. It should have high-efficiency desalination rate at high flow rate.
2. It has high mechanical strength and service life.
3. Can function under lower operating pressure.
4. Good chemical stability and high cost performance.
