A belt filter press squeezes water out of sludge or slurry between two moving belts so what leaves site is a stackable cake instead of tankers of liquid. It is hired by the month rather than the day, commonly from around $4,000, and the machine is only part of what you are committing to. Power, wash water, polymer and somebody to run it are the rest.
What the machine does and why it is hired
Slurry is conditioned with polymer, drained on a gravity section, then pressed between belts through a series of rollers. The output is a cake you can load and haul and a filtrate stream you have to put somewhere. Hire makes sense when the volume is temporary: a lagoon clean out, a dredging job, a plant shutdown.
Priced by the month, with a service call
Fleets that hold this kit quote monthly, often with mobilisation each way and a commissioning visit that gets the polymer dose and belt speed right for your material. Ask what the visit includes, what the shortest hire period is, and whether a technician is available if the belts start blinding mid job.
Power, water and polymer are your lines
The press needs a three phase supply or a generator sized for it, a clean wash water supply at pressure for the belt sprays, and a steady polymer feed. None of those normally comes with the machine. Sort the electrical connection before delivery, because a press waiting on a hookup is still on hire.
Sizing by belt width and feed rate
Presses are sized by belt width, and throughput depends as much on what you are dewatering as on the machine. Give the yard the solids content, the total volume and the window you have. A press too small runs day and night and still falls behind; one too large costs more and is no faster on thin feed.
Questions people ask about belt press rental
Can I hire a belt press for one week?
Rarely. Mobilisation, setup and commissioning take a meaningful share of a short hire, so fleets quote by the month and some set a longer minimum. If the job really is a few days, ask about a mobile dewatering service run by their operators instead of hiring the machine bare.
What power supply does a belt press need?
Three phase in almost every case, sized for the drives, the feed pump and the polymer system together rather than for the press alone. If site power is not available, a towable generator is hired alongside and the yard will tell you the kW to specify. Confirm voltage and phase before delivery day.
Belt press or geotextile dewatering bags?
Bags are cheaper to start, need no power and suit intermittent low volumes, but they need space, time to drain and a place for the filtrate. A press costs more and needs attention, and it turns a continuous flow into cake on a predictable schedule. Volume and how long you have decide it.
