Filed: 1986-02-28
Abstract: PURPOSE:To enable accurate analysis and measurement of water quality with an easy sampling of a top liquid sample in a water quality analysis for soluble impurities in water containing sludge, by passing the water containing sludge through a parallel flow filter to use the filtrate as sample. CONSTITUTION:A water containing sludge 1 undergoes a circulating agitation in a tank 2 while being filtered with a sintered metal filter 4 provided as being bypassed to a circulation line to separate the filtrate necessary for analysis in the subsequent process from a solid matter of the water containing sludge to sample. Then, the filtrate separated with the sintered metal filter 4 is subjected to a water quality analysis 5 as sample water. The parallel flow filtration is a process in which a waste liquor is made to flow parallel over the surface of a porous filter material, to withdraw a part of the waste liquor outside the filter material as filtrate. When the long-term use causes a higher different pressure 7 of the sintered metal filter 4, the sintered metal filter 4 is counterwashed by water 6 to restore.
