Abstract

PURPOSE: To control the conditions for operation of a pressure filter under an optimum condition by a method in which the conditons of the filter are compared with various data from previous cycles and the charging time of a material to be filtered in the next cycle is corrected.
CONSTITUTION: A chemicals-mixed slurry is charged into a pressure filter 5 through an integrating flow meter 3 for a certain period of time, and then pressed and dehydrated to dehydrated sludge cake 5a. In the other hand, a controller 11 incorporated with devices for timing, storing, accumulation, comparison, correction, etc., stores the amount and charging time of the slurry filtered in the previous plural times of cycles and then calculates and compares the stored data to correct the charging time of the slurry in the next ccycle.
