Abstract

A back-washable membrane filter, i.e. containing pores of approx. 1 mu diameter, is furnished on both its faces with a gauze sieve, the edges being sealed by melted resin or glue. The gauzes are pref. intermediate layers between the membrane and two support sieves, thus permitting considerably increased throughput during normal operation and back-washing.
