Abstract
An ultrafiltration membrane containing at least partially calcined particulate kaolin; coal fly ash as defined by ASTM C618-22; activated carbon having a surface area of at least 1000 meter square per gram (m2/g), as determined by Brunauer-Emmett-Teller (BET) analysis; and, a hydrophilic polymer binder. The ultrafiltration membrane is in the form of a compressed powdered solid. Particles of the at least partially calcined particulate kaolin, the coal fly ash, the activated carbon and the hydrophilic polymer binder are homogeneously dispersed within the ultrafiltration membrane.
