Abstract
The inventions discloses a method for reducing fouling on the surface of a ceramic membrane or filter with a recalcitrant filtration cake thereon that is non-responsive to regular back-flushing or other physical means of removal, where the ceramic membrane or filter is subjected to steam fast-flushing by injecting steam directly in feed channel of the ceramic membrane or filter while back-flushing the ceramic membrane or filter at the same time to heat and remove fouled layer on the ceramic membrane or filter while cooling a selective layer of the ceramic membrane or filter to avoid thermal shocking of the ceramic membrane or filter, the surface is cleaned with the ceramic membrane or filter being stationary.
