✦ Synopsis
Recent work has shown that, flux decline due to precipitation of a scaling salt such as CaS04 on RO membranes, is governed by a surface blockage rather than a cake filtration mechanism. Crvstal growth sites. scattered on the membrane, spread out laterally, increasingly blocking the membrane free flow area. Flux decline, resulting from gradual blockage of the membrane flow area, is analyzed for both laminar and turbulent flow conditions. Predicted results are shown to conform to experimental observations.
