1500 m~2 pressurised filtration-interactions between field practice and drawing board

摘要

Continuous pneumatic pressurised filtration is agenerally well-proven solid-liquid separation process ofhardcoal preparation. Different ways to improve theperformance of pressurised filters - like high-pressure water jetcleaning of filter cloths, combined flocculation and optimisationof control heads -have been tested in laboratory experiments andfield tests. The results are shown and discussed.
