The test temperature of reverse osmosis membrane is 25℃. The normal working temperature is 5~45℃. The water output will change with the change of temperature. The value of software testing increases or decreases by 3%. But the actual operation will not be like this. According to this value, we can determine how much water will be produced at 5℃ and how much water will be reduced at low temperature. When making equipment, the temperature change will be considered in advance, and the pressure can be adjusted appropriately to relieve it.
If the temperature is too low, the desalination rate will decrease. But it will not change much.
I am a RO membrane manufacturer, hehe.
