Title
Articles / Optimum Dewatering System and Conditioning Characteristic of Sludges
이용두Yong Doo Lee
Abstract
Experiments were conducted using a variable speed mixer with velocity gradient(G) values ranges from 100∼700(1/sec) with cationic high molecular weight polymer and alum sludges. CST(Capillary Suction Time) tester was used to measure relative changes in filterability. Results indicated that readily dewatered sludges can be obtained when subjected to high stress mixing conditions. These results means that standard jar tester was founded to be inadequate when predicting polymer dose requirement And Dewaterability was measured pressure filters tester. As a results, Different improvement is needed for each dewatering system.
