100psi Extra Low Pressure Industrial Reverse Osmosis RO Membrane for Water Purifier
Influent requirements of reverse osmosis membrane:
As the most important component in the water treatment system, the reverse osmosis membrane must be pretreated before the water is passed into the reverse osmosis membrane, so that the water quality can reach a certain standard before it can pass through the reverse osmosis membrane, otherwise the reverse osmosis membrane will appear. Often clogged or contaminated.
1. The SDI of the incoming water is reduced to about 5.
2. The free chlorine in the influent water should be reduced to below 0.05ppm, and the oil content: <2mg/L.
3. Influent water source: suitable for various water sources, the maximum sludge concentration is 15000ppm.
4. pH (running): 1~12
5. pH (cleaning): 1~12
6. Temperature (℃): 5~45
7. Feed particle size: ≤2mm, the pool where the membrane is located should not contain sharp objects that damage the membrane, such as branches, plastic sheets, sand particles, etc.
