A filter press is one of the oldest and most trusted pieces of dewatering equipment. It’s used for wastewater treatment across a variety of industries and applications. A filter press works by separating out solids from liquids, removing impurities, and suspended solids from industrial wastewater. This allows plant managers to easily handle and dispose of waste while returning clean water to their systems.
Filter presses separate liquids and solids. Specifically, the filter press separates the liquids and solids using pressure filtration across a filter media. Afterward, the slurry is pumped into the filter press and then dewaters under pressure.
Basically, the concentrate filter press design is based on the dewatering volume and type of slurry. ChemREADY is an expert in liquid and solid separation and offers a wide range of filter press types and capacities to suit specific application needs for trouble-free, economical dewatering.Since filter presses work using pressure, equipment that increase pressure through the means of high-pressure technology are great for optimizing your dry tailings filter press system. That’s the secret to success for Matec® filter presses, which use pressures of 21 to 30 bar to handle even the most difficult and hard to treat slurries, no matter the sector or application.
When used in combination with each other, a clarifier and chemical filter press can recover 90-95 percent of your water as clean water. The remaining water will discharge with the solids from the filter press.
Here at ChemREADY, our team of water treatment experts can help bring your dewatering efforts together with a total water treatment that optimizes your systems. We can analyze your water from a chemical perspective to find the right flocculants, coagulants, and pH balancers that we can used to treat your water before it goes through mechanical separation. This helps to optimize the performance of your clarifiers and filter presses, giving you a better and more efficient total water treatment.

The Filter Press is one of the oldest filtration technologies still in use today. It was first developed in the mid 1800’s. Unlike vacuum filters, which operate continually, the Filter Press and many other pressure filters run in batches. After a batch of slurry has run through the filter, and the filtrate drained out, it must shut down, open the filter pack, and discharge the solid cake.
The components of a featured filter press include the frame or skeleton and the filter pack. The filter pack consists of plates, sometimes frames, and filter media.
Stationary Head- The side of the frame without the closure system has a head that aligns with the filter pack. It is also known as the fixed head. It has a feed hole for the slurry to enter and drain hole for filtrate to exit.
Follower Head- The hydraulic ram pushes the follower head, or thrust head against the filter pack. There are no feed or drain holes on this head.
Closure System- A hydraulic ram is used to press the plates together and hold the filter together during operation. It creates a positive seal and prevents leaks.
Sidebars- The smelting washing filter press plates rest on sidebars to keep alignment and bear weight.
