When is a Filter Press Needed?

A filter press is typically used as a batch filtration system in industrial waste treatment operations where a slurry is generated from the manufacturing process. The goal is to separate heavy solids from liquid. Filter presses are also used in many other processing operations. In these applications, the solids may be the desired end product and in others, the filtered liquid is the ultimate goal.

In an industrial wastewater treatment application, a slurry is a waste product that is generated from a manufacturing process. Due to high disposal costs, the goal is to reduce the amount of wastewater that is sent for disposal. Since wastewater disposal cost is based on the quantity of waste to be hauled, the goal in these applications is to reduce the amount of waste that is sent to disposal facilities. The filter press takes a slurry, often from a sludge thickening tank and condenses the solids into a filter cake by forcing the liquid through the filter press membranes, thereby concentrating the solids. The drier cake will reduce the overall sludge volume. The liquid, or filtrate, can then be sent back to the waste treatment system for further treatment or in some applications, can be used for non-critical rinses or it can be sent to a final pH adjust before being reused or sent to the sewer for disposal.

Met-Chem has the ability to test your slurry to determine if a filter press is a viable option and to determine which fabric is the best solution for your filtration needs. There is a minimal fee associated with this testing but it can be applied to a future filter press purchase.
