Abstract

PURPOSE: To enhance the effect of freezing treatment by changing the electric conductivity of sludge to be treated.
CONSTITUTION: At prestage of a freeze-melt unit 2, is installed a sludge quality reforming tank 4 containing cation and anion exchange resin membranes so that the electric conductivity of supplied sludge being treated can be changed. And a dehydrator unit 3 is installed downstream. Thus, lowering the electric conductivity of the treating sludge enhances dehydration property after freezing treatment by the freeze- melt unit 2.
