Filter Cake Discharge Options
Hoppers & Dumpsters
M.W. Watermark can provide a self-dumping cake hopper (also known as a dumpster) for almost any size press for easy handling of discharged solids. The hoppers are furnished with large ball-bearing casters for easy positioning under the presses, either manually or by using a lift truck. When filled, the operator picks up the hopper using a fork lift truck and positions it over a larger container. It’s emptied quickly and easily by pulling the spring-loaded self-dump pin.

Leg Extensions, Chutes and Platforms
If you are using a smaller press, M.W. Watermark offers leg extensions and discharge chutes to allow filter cake to be discharged directly to a drum or bulk bag. The extended legs raise the press to allow room for a single or multiple barrels to catch the filter cake when released from the press. Smaller filter presses may still be operated from ground level.
Larger filter presses can be equipped with an elevated platform that allows roll-off containers to be placed underneath. A “roll-off” platform can be very efficient when managing a large volume of filter cake, as the wheeled bins can be loaded onto a truck relatively quickly for haul-away.

M.W. Watermark can supply an integrated screw conveyor to transport the filter cake to single or multiple discharge locations. This can eliminate the need for a forklift or platform while minimizing operator time handling the filter cake. It can also provide the option of discharging to a nearby location or a truck/trailer to be hauled for disposal using an optional inclined conveyor. Discharge chutes are included, either in steel or translucent polycarbonate, to direct the filter cake to the conveyor and provide operator protection.

The automatically actuated drip trays catch any filtrate that escapes from between the filter plates during the dewatering process or when power washing the plates and cloths. The trays are held in the horizontal sloped position during dewatering or cloth washing and rotated to the vertical position for cake discharge. Actuation of the trays is either by air or hydraulic cylinders. The trays slope to the non-operating side of the filter press, where the flow is directed to a launder. The launder can be piped for recycling, or to a drain depending on project requirements.
