Tips: How to avoid damage to reverse osmosis (RO) membrane?
There are many situations that cause reverse osmosis membrane damage. In the daily experiment process, laboratory personnel do not pay much attention to the use of equipment, so the service life of the ultrapure water system is also shortened. What should be paid attention to in daily use?
1. Raw water quality
The water used in the laboratory is mostly tap water, and the quality of the water source varies from region to region. The macromolecular substances in the raw water are not completely removed and pass into the reverse osmosis membrane when they pass through the pre-treatment device of the laboratory purification water system, which easily causes the reverse osmosis membrane to be blocked.
2. Improper operation
The residual gas in the purification water system runs under high pressure, and the formation of an air hammer will damage the RO membrane. Therefore, it must be ensured that the remaining air is exhausted under the pressure of 2 to 4 bar, and then the pressure is gradually increased.
If the device is turned on repeatedly, it will cause unstable pump pressure and even cause RO membrane breakdown.
3. Poor disinfection
If the RO membrane is used for a long period of time without regular disinfection or good disinfection, it will also cause the membrane to be contaminated with a large number of microorganisms, and long-term accumulation will cause damage to the RO membrane.
4. RO membrane pre-treatment filter is not maintained properly
Pre-treatment is mainly used to filter large particulate matter, colloids, gas, etc. in water quality, and these materials also cause great damage to RO reverse osmosis. Internally filled activated carbon generally needs to be replaced within 1-3 years, and PP cotton needs to be replaced within 6-12 months.
5. Not used for a long time
When the ultra-pure water machine is not used for a long time, the RO membrane will dry out, and the filtered impurities will be fixed on the RO membrane. When we use it again, tap water cannot pass through the RO membrane. So even if we don’t use water, we still need to turn on the machine from time to time to clear the inside.
