Membrane fouling is a major operational issue in reverse osmosis (RO) desalination plants. In particular, plants treating brackish groundwater can encounter troublesome inorganic membrane scales. A novel cleaning method is proposed to remove inorganic scales from fouled RO membranes using dissolved CO2. A comparison of cleaning methods is discusse...

Examines the use of superfine powdered activated carbon particles as pretreatment....

This paper describes the use of microfiltration membrane for the filtration of colloidal activated carbon. Efforts were made to minimize head loss and small molecule adsorption. The effects of source water quality and particle size were evaluated. The presence of natural organic matter (NOM) proved to be a confounding factor. Two methods were test...
