Study on Calcium and Magnesium Fouling of Vacuum Membrane Distillation

Abstract:

In this paper, calcium and magnesium fouling on membrane distillation process was investigated. The effect of less soluble salts with single component or multi component on flux and membrane fouling was examined, by means of synthesizing seawater. The results showed that the fouling caused by calcium carbonate and calcium sulfate was mainly formed by the attachment of the insoluble substance on the fibers. The calcium sulfate caused the blocking at inlet hole of the module. If there were less soluble salts with multi components in the feed, calcium carbonate was the main form of the fouling.
