Abstract
A review has been carried out of experience gained from industrial applications of membrane technology and the status of technical developments in this field, in order to evaluate the usefulness of this method for the treatment of process water at power plants. The review shows that membranes are used for the purification of turbine condensate in BWR stations in Japan. The iron content in the condensate is reduced from c 30 ppb to <0.1 ppb, and the equipment has functioned excellently for 4 years. At PWR stations, both ultra-filtrations (UF) and reverse osmosis (RO) are used for purification and the recovery of boric acid. The filtration gives cleaner effluent and lower costs for the low-level wastes. In order to comply with stringent environmental requirements as regards the release of chemical substances from cellulose production, UF filters are used in the purification of bleaching effluent in Japan. The plant began operating in 1980 and has resulted in a considerably improved reduction of the chemical oxygen consumption by the waste water. Recently, a filter with an UF membrane for the treatment of bleaching effluent has been taken into use in Husum, Sweden. The same type of filter (CR) is used for the
