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.

- When PH is above 10, the Maximum Temperature of Continuous
Operation is 35ºC.
- Under certain conditions, the presence of free chlorine and other
oxidants in the water may cause serious membrane damage, which
doesn't belong to product warranty range.
