Abstract

PURPOSE: To eliminate wasteful pressure losses owing to excess filter cake and obtain the filter cake of a constant moisture content by stopping the supplying of raw water and pressing according to the respective degrees of decrease in filtrate and dehydration rates at the time of forcibly feeding the raw water between two sheets of sandwiched filter cloths, filtering the same and pressing the filter cake.
CONSTITUTION: The raw water in a coagulating and intimate mixing tank 14 is fed from the supply mouthpiece 6 of a filter press 13 between the filter cloths 4a, 4b between the filter plates 1 by a pressure feed pump 15, and is thereby filtered. The flow rate measuring devive 20 in discharge pipe 19 connecting to the communicating hole 9 for withdrawal of filtrate and dehydrated water measures the flow of the filtrate shown in the graph. At the time t1 when this rate reaches a preset water flow rate, the pump 15 is stopped by signal. Thence, a pressing pump 18 starts and at the time t2 when the quantity of dehydrated water owing to pressing of the filter cake of diaphragm plates 10 reaches the set extent in the same manner as mentioned above, the pump 18 is stopped.
