Abstract

PURPOSE: To obtain dehydrated cake with low water content by contacting concentrated sludge prior to dehydration with exhaust gas generated from a drying procedure to romove dust from the exhaust gas and cool said gas as well as to dehydrate the sludge effectively.
CONSTITUTION: The exhaust gas S1 from a water treating process is introduced into a concentrating tank 6 and concentrated sludge S2 is sent into a scrubber 5. Herein, said concentrated sludge S2 is contacted with the exhaust gas S5 from a dryer 4 to carry out the dust removal and the cooling of said gas S5 of the dryer 4. The treated exhaust gas E is discharged to atmosphere and concentrated sludge S3 temp. of which is increased by the contact with said exhaust gas is introduced into a dehydrating device 2 along with a flocculating agent G. The obtained dehydrated cake B is sent to the dryer 4. Thereby, the treatment with good waste heat recovery ratio can be carried out efficiently.
