Effects of Water Temperature on Membrane Flux

We know that RO flux reading can be affected by temperature, pressure, flow rate and others. But the biggest factor I can see is the seasonal temperature of the water. Has there been any studies for or is there any mathematical way to get a true flux reading when only the temperature is only factor that changes seasonally?

Yes, the effect follows the viscosity of the water.  As the viscosity decreases at a higher temperature, more water goes through the membranes.  At lower temperatures, the viscosity increases and so less water passes through the membrane.  This results in the flux changes you have been noticing.

Tables showing the temperature effect are usually available for each membrane module by actual measurement.  See our Temperature Correction Factor Information Page and Table more information.
