Abstract

PURPOSE: To enable the dehydrated cake of always a fixed water content to be obtained by detecting the flow rate and concentration of the sludge to be press-fed into a dehydrator and so controlling the flow rate of the pressurized water that it provides the amount of the pressurized water calculated from the above-mentioned results and the preset cake moisture water content.
CONSTITUTION: The flow rate and concentration of the sludge from a pump 12 being press-fed into a filter press type sludge dehydrator 13 used for a sewer age plant are detected by a flow rate measuring device 16 and a concentration measuring device 17; the signals of the integrated value Qs of the sludge flow rate and the sludge concentration Ds as well as the flow rate integrated value Qw etc. of the pressurized water detected by a flow rate measuring device 18 are inputted to an arithmetic control unit 19; the operations by the formula are made from the preset water content K of dehydrated cake and the volume Vf of the filter chamber inside and the dehydration is continued without giving any stoppage command of the pressure pump 15 to a sequence device 20 until the formula holds. Thus, even if the concentrations of the sludge being press-fed into the dehydrator fluctuates, the water content of the dehydrated cake becomes constant.
