Abstract

PURPOSE: To prevent the lowering of efficiency due to useless washing by maintaining good filterability of a filter cloth always by automatically detecting a bad condition of filterability due to the clogging or the contamination of a filter cloth to control the washing so as to carry out the washing of a filter cloth in good timing.
CONSTITUTION: In a coagulation and mixing tank 11, a sludge to be dehydrated is stored and transferred under pressure to a dehydrator 13 from the coagulation and mixing tank 11 by a sludge pressure pump 12. In a compression procedure, pressurized water is introduced under pressure into a pressure chamber of the dehydrator 13 from a pressurized water tank 14 by a pressurized water pump 15 and a squeezed and dehydrated cake is remained in a filter chamber and a separated water is flowed outwardly through a filter cloth. Now, an operation control apparatus 19 receives signals from a flow amount measuring apparatus 16, a filter degree measuring apparatus 17 and a flow amount measuring apparatus 18 to carry out predetermined operation. As a result, if a water content of the dehydrated cake becomes higher than a predetermined water content thereof, the operation control apparatus applies the output of a washing order of a filter cloth to a dehydration Siekens control apparatus 20. When an input of a washing order of a filter cloth is not applied, the dehydrator is returned to a frame closing procedure and dehydration works are repeated.
