Abstract
For diagnosis about present conditioning and dewatering system, conditioning experiments were conducted using a mixer with velocity gradient(G) value 277(1/sec) with cationic high molecular weight polymer and sewage sludges. CST(Capillary Suction Time) tester was used to measure relative changes in filterability. Results indicated that present conditioning system must be corrected. In the view of the characteristic of region and the duality and quantity of sludge, reuse after incineration or restoration in farmland after the decrease of heavy metals and nitrate nitrogen is desirable.
