Evaporators /Filter Press

wock-oliver’s filter presses are used for the purpose of dewatering sludge and slurry produced in wastewater treatment, and chemical and mineral processing. Most wastewater treatment processes will produce sludge or slurry that is commonly disposed as a liquid waste. This sludge or slurry can be dehydrated in an wock-oliver’s filter press via a method called sludge dewatering. By using an wock-oliver’s filter press a reduction of up to 90% sludge volume can be achieved.
in most instances the sludge or slurry is conditioned with polyelectrolyte and then dewater in an wock-oliver’s filter press to produce a solid dry filter cake.

the filter press has been the focus of manufacturing for many years. We have built a solid reputation for building quality filter presses, clarifiers, sludge dryers, complete waste treatment systems, filter cloths and filter plates plates. Our filter presses have been used in a variety of industries from plating and metal finishing to chemical and food processing to name a few. Wock-oliver filter presses feature heavy duty steel construction with polypro gasketed plates. These filter presses can be manufactured with manual or automatic closures, but always with a hydraulic cylinder for sure, high pressure closing. Wock-oliver filter presses are always expandable for larger future capacity by adding longer sidebars and additional plates.

standard filter press features:
+ air driven hydraulic closing pump with pressure gauge on automatic units
+ 2 stage hand pump on manual units
+ heavy duty hydraulic cylinder for opening and closing of press
+ polypro gasketed recessed plates for leak free operation
+ air blown manifold piping for air drying filter cakes
+ air line filter, oiler, regulator and gauge on automatic units.

optional features:
+ sludge dump carts for sludge collecting and dumping
+ cat-walk platform with raised legs for disposal into drums or our sludge dryer
+ automatic plate shifter for ease of cleaning
+ distance piece for future expansion
+ leg mounted control panel
+ diaphragm pump for solids feed to the filter press.

filter press applications:
+ dewatering industrial sludge
+ reclaiming precious metals
+ processing of pharmaceuticals
+ product filtration
+ dewatering hazardous wastes
+ process waste waters in epa approved treatment systems
