Abstract
PURPOSE: To operate the whole equipment effectively, by detecting the change of feeding amount of condensed sludge for dehydrater and filtration flowing amount of the dehydrater, and controlling the change-over to the compression process or its ending at the filter press type dehydration equipment.
CONSTITUTION: Concentrated sludge is supplied to the condensation mixing vessel 4 operating the pump 7 by the information processing apparatus 26 when the level of the vessel 4 is measured. The pump 7 is stopped when the supply amount is reached the operation value and flocculant and next, auxiliary agent, are supplied. Feeding is stopped and compression operation of the dehydrater 5 is carried out when the feeding amount is decreased and the amount of filtrate of the dehydrater 5 is decreased, at the time of sending the concentrated sludge formed in the vessel 4 to the dehydrater 5. Compression process is stopped when the amount of the filtrate is decreased. The above operations are controlled by the apparatus 26. By the above method, overs and shorts of condensed sludge amount by the change of dehydration efficiency, is eliminated and effective operation is carried out.
