Abstract
Method, and appts., of operating a hollow fibre filter unit or a filter bank subjected to a backwash cycle, in which (a) the fibre lumens are drained of filtrate (b) the feed flow is terminated with feed remaining on the feed side of the filer and gas is applied to the lumens to pressurise the or each filter unit (c) the pressure on the feed side of the filter is re released whilst the gas pressure is maintained and there is no flow of feed (d) flow of feed is resumed and gas pressure maintained in the lumens to carry all of the accumulated detritus out of the filter (e) the gas pressure is removed from the filtrate side of the or each filter unit and filtrate is allowed to refill the lumens and (f) the or each filter unit is pressurised so as to replace the gas in the pores of the membrane with liq.
