When the water temperature rises, in some reverse osmosis systems operating at constant flow, the desalination rate of the system will decrease.
This is due to the increase in water temperature leads to a decrease in viscosity and increase in water flux. If the constant flow operation is continued, the operating pressure required to produce the same flow of water will decrease, and the decrease in operating pressure will result in a decrease in the desalination rate. The regeneration cycle of the subsequent desalination equipment will also shortened at the same time.
In order to keep the desalination rate of the system unchanged, it is necessary to adopt constant pressure operation, but at this time, the water production will increase, and as the temperature rises, the water production will continue to increase.
Therefore, under the condition of high water temperature, the maintenance of system performance needs to be adjusted according to actual needs.
