ABSTRACT:
A filtration system having an intermittently moving belt on which is deposited a suspension to form a filter cake. A press is provided above the belt comprising one or more pressure cushions, and suction chambers are disposed below the belt. A control system coupled to the cushions and the chambers controls application of pressure to the former and suction to the latter to press the cushions down on the filter cake formed on the belt and to draw off moisture from the compressed cake, the action of applying pressure and suction halting movement of the belt. After filtering the cake the pressure and suction are removed allowing the belt to move forward and another filtration cycle to start on the next section of the filter cake formed on the belt.
