The following situations will cause reverse osmosis water production to decrease, which can be checked according to the actual situation:
1. If the working pressure reaches the rated working pressure, determine the rated working pressure. According to the reverse osmosis membrane model, appropriate increase of water inlet pressure can increase water production.
2. The reverse osmosis membrane is contaminated, which can be determined based on the operating pressure difference.
① Granular pollution: sediment, pretreatment fine filter material, etc. ;
② Biological pollution: bacteria, viruses, algae, etc. ; ③ Organic matter pollution: iron, aluminum oxide, etc. ;
④Pollution by inorganic materials: carbonate scale, sulfate scale, fluorine, silicon scale, etc.
Targeted offline chemical cleaning can essentially restore productwater ion.
3. The influence of water temperature. Rated reverse osmosis water production is based on a 25°C design. For every 1°C decrease in temperature, water production will decrease by 2 to 3%.
