摘要：

Investigations have been made into techniques of removing sewage fouling from cellulose acetate membranes using a pilot scale reverse osmosis unit. It has been found that reductions in the pH of solutions surrounding the membrane when not pressurised are effective in loosening the fouling. The cleaning technique has been outlined and physico-chemical studies are described which are able to produce an explanation of the mode of action of the pH effect. © 1979.
