Abstract

PURPOSE: To provide an apparatus for detecting freeze of sludge, which is capable of indicating the extent of freezing of sludge, by measuring current passed between electrodes that are inserted into sludge.
CONSTITUTION: A pair of electrode rods 4, 4 are inserted into sludge 1 which is filled in a sludge freezing tank 2, and they are connected to a detector 3 for detecting electric resistance. By the detector 3, electric resistance varied as freezing of sludge progresses is measured, and an output signal corresponding to the electric resistance is given from output section 5. On the basis of this output signal, indicator 6 indicates the extent of freezing of sludge at the time.
