Filter presses are used for separating solids from liquids. Our offer includes help in solving sludge concentration and various types of sewage treatment processes issues.

EKO-PRESS produces chamber and membrane filters used for mechanical dewatering of sludge of various origins. Thanks to utilising modern filtration technologies, it is nowadays the most effective and cheapest method of thickening available on the global market (high efficiency of sludge thickening and filtration).

We also modernise legacy presses: filtration packets changing and construction, hydraulic and control systems repairs.

Filtration tests are conducted with the use of a mobile testing press (efficiency assessment, process parameters selection, cloth selection etc.). These tests expressly illustrate the possible performances of filtration, and often encourage future users to invest in that direction.


EKO-PRESS offers advanced control systems for one, as well as for a set of presses, ensuring simple handling, operating reliability and full synchronisation of appliances. We also offer automatic high-pressure filtration cloth washing systems (of water pressure up to 130 bars).

Filter press operation:

Filter press operational cycle begins with press filling: the pump pumps the suspension to be filtrated into the press chambers, the liquid flows through the filtration cloth, which concentrates the solids, creating a layer of growing thickness, popularly called the cake. The flow resistance and chambers pressure raises, while the amount of the drain gradually ceases. At that time, the filtration can be interrupted, and the mechanical or automatic press unloading (by sliding apart successive filtration plates) can begin.

The compacted sludge in formed cakes falls out to the container or onto the conveyor and is transported to the chosen destination, which ends the press operating cycle. The duration and efficiency of the cycle depends on the physicochemical characteristics of the filtrated medium and – among others – on its individual capabilities to output liquids.

In the case of membrane filter presses, after the phase of press filling and before the unloading phase, the cake is mechanically pressed by membranes installed on plates (pressure up to 16 bars). This allows for additional reduction of liquid percentage in the cake (ranging from few to more than a dozen percent). Sometimes, it is also necessary to remove unwanted agents, such as Cl-. This process is performed before the press unloading by means of multidirectional and slotted penetration of the pressed sludge by water.
