Title: Method of controlling and optimizing operation of porous belt press for filtering slurry
Inventor: FURANSOWA KISUTORAA
IPC: B01D37/02
Filed: 1986-03-18
Abstract: A level measuring sensor is arranged at the start of the straining zone in the perforated belt press and this in particular measures the level change and then regulates the flocculant inflow. In order that the level in the straining zone is stabilized, the perforated belt press must operate in the overflocculation zone. If the flocculant inflow is reduced to the technically possible operating limit, the dry substance content of the filter cake has an optimum value. Thus, the optimization of the control of the operation of the perforated belt press can be reduced to a relatively simple measurement of a level or the time changed thereto.
