Reverse osmosis membrane is an important component of laboratory ultrapure water machines, which filters and treats impurities in water through small pores. Therefore, after long-term use, it may be blocked for various reasons, which can affect the quality of our effluent. If we want to solve the problem, we need to know the causes of reverse osmosis membrane blockage. Only by clarifying the reasons can we find the correct solution and avoid the occurrence rate of such problems:

1. High hardness of raw water: In some areas, due to the relatively high content of calcium and magnesium ions in the water, the hardness of the water is higher. The reverse osmosis membrane can work for a long time in this environment. Scaling is prone to occur, which will reduce the water production of the equipment.

2. Raw water contains bacteria, organic matter, and colloids: Due to geological and other factors, the content of bacteria, organic matter, and colloids in some areas may be relatively high, which can also block the reverse osmosis membrane.

3. High turbidity of raw water: In some urban and rural areas, laboratory water contains more impurities, such as sand and turbidity, which can accelerate the pre-treatment blockage of laboratory ultrapure water machines, leading to blockage of reverse osmosis membranes.

4. High residual chlorine content in raw water: In areas with high residual chlorine content in severely polluted water, residual chlorine can oxidize the reverse osmosis membrane and quickly reduce its desalination rate.

5. Change in inlet pressure: In addition to raw water quality issues, the change in inlet pressure of the laboratory ultra pure water machine is also an important reason for the failure and blockage of the reverse osmosis membrane. The inlet pressure is unstable and varies greatly, and in some cases, it can break through the reverse osmosis membrane, causing water leakage in the ultrapure water machine.

The above are some of the main reasons for the blockage of the reverse osmosis membrane in the laboratory's ultra pure water machine, most of which are due to the increase in reverse osmosis load caused by poor raw water quality. In response to the above situation, Upu Laboratory's ultra pure water machine is equipped with various pre-treatment devices based on the quality of raw water in different regions. Firstly, pretreatment is ensured to reduce the load on the reverse osmosis membrane. However, the lifespan of the reverse osmosis membrane itself is affected by water quality and water consumption. When properly maintained, the reverse osmosis still blocks. It is recommended to contact after-sales personnel for timely replacement to avoid affecting water quality.
