Strategies to prevent membrane fouling during the filtration of wastewater

摘要

Although membrane filtration is a well know process for separation issues, membrane fouling is still the Achilles' heel of the processes. Depending on the fouling the economics benefit of the process can be dramatically reduced. Fouling is the accumulation or deposition of suspended and dissolved particles on the membrane surface or in the structure of the membrane. The fouling can vary from large suspended particles to small colloids, molecules or bacteria.
