Abstract
The Ministry of Public Welfare in Japan is proceeding the development for applying the membrane technology to drinking water treatment. Recentry, Daicel Chemical Ind. Ltd., succeeded in the development of cellulose acetate (CA) hollow fiber ultrafiltration membrane. The CA membrane is the most suitable for the treatment of natural water because of its high flux and low fouling properties.
In this review, we show the performance of this CA membrane and introduce the newly-developed hollow fiber module using the CA membrane, which has large filtration area of 50 m2.
