Hangzhou Guotai Environmental Protection Technology Co., Ltd. is a high and new technology enterprise, has undertaken 5 projects at provincial or ministerial level, in which the technology of sludge depth dehydration has been listed as sub-project of national special major protect of water body pollution control and management technology.
Technology of sludge depth dehydration has passed the provincial new technical appraisement, the technological level is advanced in China.
Technology of sludge depth dehydration researched and developed by Hangzhou Guotai Environmental Protection Technology Co., Ltd.
Process route of technology of sludge depth dehydration
At first, add in bound water transforming agent researched and developed by Hangzhou Guotai Environmental Protection Technology Co., Ltd. to destroy flocculation state of sludge, then transform majority of bound water in sludge into free water and make sludge transform from semi-solid state into flow state; in addition, remove the stink components in sludge, absorption system for tail gas absorbs standard discharge; then add in complex precipitation agent, stabilizing agent, filter aid, etc. to fix heavy metal substance and other poisonous and harmful components in sludge, and further eliminate the stink components in sludge.
Then deliver the sludge to filter press with pumps in order to separate moisture in sludge in the form of liquid. Moisture content of dry sludge after dehydration is around 45%.
