Ceramic membranes gain use, but plenty of ‘ifs’ still remain

When it comes to ceramic membranes for microfiltration projects, the jury is still out — but keeping an open mind. In fact, some membrane technology experts see growing acceptance of ceramics versus polymeric membranes in larger-scale water and wastewater treatment facilities. Ceramic membrane filtration is a mild, highly selective process. The medium to be filtered — raw water, for example — flows through the channels of the membrane carrier. Particles are trapped if their size exceeds the radius of the membranes pores, while the filtered material permeates through the pores on its way to continued processing. Polymeric membranes are microporous films,
