Porous Elastic Filter Material in Water Depth in the Processing of the Application

Abstract:

Investigation porous elastic filter material deep treatment of drinking water contamination removal in effect. The membrane separation system to meet the requirements of the feed water quality, in this paper the new type of porous elastic filter material compression filter technology and traditional quartz sand filter technology water depth contrast the treatment effect experimental study. The results showed that different compression ratio of porous elastic filter material to filter pollutants has good removal efficiency, and better than quartz sand. Porous elastic filter material compression ratio and turbidity, the average iron removal rate was significantly positive correlation. The compression ratio for 70% of the porous elastic filter material after filter, and the effluent turbidity of, iron, CODMn and DOC average concentration of were 0.35 NTU, 0.05, mg • L-1,1.73 mg • L-1 and the 1.48 mg • L-1; Basic meet the membrane separation system of the feed water quality requirements.
