An apparatus for coagulating treatment which is capable of controlling the amount of addition of a coagulant to the optimum level thereby minimizing the water content of the dehydrated cake comprises coagulant adding devices (6), (7), and (8) for causing the coagulant to be added in a variable amount to a liquid subjected to the coagulating treatment, a heat transfer detecting meter (12) disposed so as to contact the liquid to which the coagulant is to be added, the liquid to which the coagulant has been added, or the filtrate from the liquid to which the coagulant has been added and adapted to detect a feeble change in the physical property of the liquid in the form of a change in voltage, and a control device (16) for controlling the amount of addition of the coagulant in the coagulant adding device (8) so that the value of detection of the heat transfer detecting meter (12) is minimized or kept within a desired range.
An apparatus for effecting coagulation by addition of a coagulant to a liquid, comprising
A coagulating apparatus for effecting coagulation in a liquid by addition of a coagulant, comprising first guiding means for receiving a liquid to be subjected to a coagulating treatment and guiding the received liquid to at least one part at which the coagulant is added, adding means for adding the coagulant to the liquid in a variable amount at the part for addition of the coagulant, solid-liquid separating means for separating the liquid with the coagulant into a liquid content and a solid content, second guiding means situated between the adding means and the separating means to guide the liquid to the separating means, a heat transfer detecting meter disposed so as to contact the liquid content separated by the solid-liquid separating means, and control means for controlling an amount of addition of the coagulant through the adding means so that a value of detection of the heat transfer detecting meter is minimized to be within a target range.
