Used Filter Presses for Sale
Filter presses are industrial filtration systems designed to separate solids from liquids using pressure-driven filtration through a series of filter plates and media. These systems operate by pumping slurry into chambers where solids are captured and compressed into filter cakes, while clarified liquid passes through. Used filter presses are widely utilized in wastewater treatment, chemical processing, mining, food production, and pharmaceuticals. Aaron Equipment offers used filter presses for sale in a range of plate sizes, configurations, and capacities to support various dewatering and filtration requirements.

Filter Press Applications & Typical Use Cases
Used filter presses are commonly used in applications requiring efficient solid-liquid separation and dewatering. Typical use cases include:
Sludge dewatering in wastewater treatment
Chemical slurry filtration and solids recovery
Mining and mineral processing
Food and beverage filtration processes
Pharmaceutical and fine chemical production
These systems are essential for reducing waste volume and improving material recovery.
When to Choose a Filter Press
Filter presses are best suited for applications requiring high solids capture and dry filter cake production. They are typically selected when achieving low moisture content in solids is critical. Compared to other filtration systems, filter presses offer high efficiency and produce clearer filtrate, making them ideal for batch filtration processes with high solids content.
Used Filter Press Buying Considerations
When evaluating a used filter press, consider:
Plate size and number of plates: Determines filtration capacity and throughput
Operating pressure: Impacts filtration efficiency and cake dryness
Plate type: Recessed, membrane, or plate-and-frame designs affect performance
Hydraulic system and controls: Ensure reliable plate closure and operation
Filter cloth condition: Impacts filtration quality and maintenance requirements
Why Buy Used Filter Presses
Purchasing a used filter press can significantly reduce capital costs while maintaining effective solid-liquid separation performance. Many units are available for immediate delivery, helping facilities avoid long lead times associated with new equipment. Used filter presses also provide access to proven systems capable of handling demanding filtration applications.
Sell Your Used Filter Presses
Aaron Equipment purchases surplus and used filter presses from a wide range of manufacturers and configurations. Whether you are upgrading filtration systems, shutting down operations, or selling idle equipment, our team can assist with buyouts or consignment opportunities.
A filter press is a filtration system that uses pressure to separate solids from liquids. It consists of a series of plates that hold filter media, forming chambers where solids are captured and compressed into cakes.
Filter presses are used for dewatering sludge, filtering chemical slurries, recovering solids, and clarifying liquids. They are widely used in wastewater treatment, mining, food processing, and chemical manufacturing.
Filter presses use pressure to achieve high solids separation and produce dry filter cakes, while other filtration systems may rely on gravity or vacuum and produce wetter solids. Filter presses are often preferred for high-efficiency batch filtration.
The cost of a used filter press depends on factors such as plate size, number of plates, pressure rating, manufacturer, and condition. Larger or specialized systems typically command higher prices.
