The use of ceramic membranes as submersible modules in membrane bioreactors

Summary

The results of laboratory testing the use of flat and tubular ceramic membranes as submersible modules in membrane bioreactors are presented. The studies were carried out with the use of flat ceramic membranes manufactured by ItN Nanovation German company and tubular membranes from Russian University of Chemical Engineering named after D. I. Mendeleyev. It was established that for the use in activated sludge media membranes with 200 nm pore size can be recommended; however, the transmembrane pressure shall be higher than –0.3 bar.
