Research on Sludge Water Thickening in Waterworks

The study was conducted on the sludge thickening properties and some factors that affect the sludge thickening in waterworks to get fundamental information for disposal of sludge water thickening in waterworks .The results show, the thickening properties of sludge will be improved by treating by polyacrylamide before the sludge enters the thickening tank and minishing space between diagonal planks can get good effects on sludge water thickening.
