Abstract

A novel hybrid membrane-adsorption process has been developed for the production of clean water supplies. A 0.2 μm ceramic membrane has been functionalised to produce a super-hydrophilic surface on the microfiltration membrane capable of maintaining flux with little or no fouling under normal operat...
