Abstract

PURPOSE: To operate a dehydrater efficiently always at optimum pressurizing time by finishing pressurizing when the interstitial water pressure of sludge drops to specified pressure.
CONSTITUTION: The interstitial water pressure of sludge is measured by a pressure gauge 8 installed in a tube 7 that communicates to the filter chamber of a pressure dehydrater 5. When the water pressure drops to specified pressure, a pump P and the pressure dehydrater 5 are controlled to finish pressurizing. Consequently, dehydration can be made always by optimum pressurizing time, and lowering of operation efficiency due to too long pressurizing time or difficulty of separation of cake from filter cloth caused by excessive water content of the cake due to too short pressurizing time do not occur.
