The Testalta Filter Press uses the same basic technology as any other filter press to dewater the muddy material and recover the reusable filtered water. The filter plates are suspended from a beam above the filter press. A hydraulic cylinder and four tension bars are used to clamp the plates together, while a sludge feed pump pushes the sludge between the plates where the sludge solids accumulate and the filtered water passes through the filter fabrics mounted on the surfaces of the plates. The plates are opened using a chain slide system mounted on the beam and designed to separate the filter plates one at a time after the set of plates has been hydraulically released.
The bottom and both sides of the filter plates are completely open and unobstructed, preventing any interference with the panel drain. The overhead beam design also allows the easiest access to the filter plates and filter fabrics for cleaning and maintenance.
