Ceramic tubular membrane

Ceramic tubular membrane modules are used to filter streams of high dissolved or high suspended solids, e.g. oily wastewater treatment. They usually consist of two tubes. The inner tube is the membrane tube and the outer tube which is the shell.

The ceramic-based inner tubes are packed into a long PVC housing. The filtering works through tangential crossflow. The feed stream goes across the length of the membrane tube and is filtered out into the outer shell.

How tubular membrane works?

The filtration of streams with ceramic tubular membranes works by pressing the water into the membrane tubes. Through the pressure the water can pass the porous structures into the outer tube (permeate) whereas solid or suspended particles exit the tube (retentate) in a tank. From there the tubular membrane filtration process can be started again. ​

Filtration with tubular membranes is a highly efficient and space-saving solution compared to traditional clarifying filter systems. ​
