sintered porous ceramic membrane filter tubes for municipal wastewater treatment

 

1:General Material Description:

Corundum filter element is a porous filter ceramic composed of corundum grains (α-Al₂O₃) sintered by a alumosiliceous bond. Main components are splintery, dense electro-corundum grains that build a finefiltering ceramic structure with very narrow pore size distribution. The special feature of this filter media is its highly porous structure with its large internal surface area. Therefore it is suitable especially for depth filtration applications.This filter elements are successfully used for the filtration of liquids and gases.
