CHARACTERIZATION OF SLUDGE FILTRATION

摘要

Buchner funnel filtration tests using an activated sludge obtained from a nearby wastewater treatment plant are analyzed in the light of the multiphase filtration theory. The multiphase filtration theory states that the controlling factor in filtration is not the resistance of the cake but the resistance of the cake-septum interface. Experimental results indicated that the pore size of the filter medium strongly affects the filter performance. It is concluded that up-flow Buchner funnel experiments must be carried out by using industrial scale filter medium.
