MEMBRANE SUPPORTING STRUCTURE AND TUBULAR MEMBRANE

摘要

A membrane is made with a supporting structure having two or more layers. One layer is embedded in the membrane wall. Another layer generally abuts the membrane wall, preferably on the permeate side of the membrane wall. These two layers are preferably bonded together. The membrane may be, for example, a tubular membrane. Optionally, the membrane may be made of materials able to work at a temperature of 80 degrees C or more.
