英文摘要: Abstract(#br)The influence of filtration membrane resistance on colloidal filter cake swelling after the filtration pressure release is discussed in frame of filtration-consolidation theory. It is argued that in the case of reversibly compressible filter cake, the solid pressure relaxation can result in filtrate inflow across the membrane with the following absorption by the filter cake part adjacent to the membrane surface. According to the model results, the filtrate inflow and the filter cake swelling rates increase with decreasing of the membrane hydraulic resistance. At low membrane resistance, the swelling can result in the non-monotonous bell-like solid concentration distribution in the filter cake (solid concentration on the cake-membrane surface is lower than the maximal solid...
