The use of ceramics (compared to polymers) offers a narrow pore size distribution exactly matching the components to be separated, resistance against aggressive chemicals, high temperatures, a high and constant flux and a long service life. Ceramic carriers are an ideal base for membranes and micro-filtration applications in the chemical, pharmaceutical and food industry as well as in water and wastewater processing.
The supports for the membrane elements are made from a-aluminum oxide or silicon carbide with open pores. This material can provide not only maximum permeability but can also fulfill high requirements relating to mechanical stability. These supports are either for a single channel or a multi-channel design. A membrane layer of a define texture only a few mm thick is applied to the inner side of the channels in a sandwich-type process and connected monolithically. TRL provide the best solutions in below application and industries.
Initially, ceramic membranes were used in wastewater technology. Meanwhile, successful solutions and possible applications cover all industries where media were filtered.
