A plate and frame press consists of a series of frame supported plates that contain facing recessed sections. This forms a void into which liquid sludge can be transferred for dewatering.
The Bucher press is a hydraulic de-juicing press consisting of a cylinder and a moving piston that squeezes the sludge allowing the water to pass through several filter elements made of porous cloth material. The sludge cake is retained inside the cylindrical shell. After the sludge enters the cylinder, it is continuously squeezed by the piston, thereby achieving a high degree of mechanical dewatering.
These technologies represent a combination of methods that may include any of the technologies described above in series. The combination of technologies is intended to produce a stackable, truckable product within a small footprint.
