    Belt filter press

    Product Review:

    Belt filter press is a high performance and efficient equipment intended for dewatering, designed using advanced foreign technologies. It is featured with long service life and can effectively pressure filter suspended solids and sediment processed by air flotation, forming solid sediment to avoid secondary pollution. Moreover, the unit is applicable for sludge concentration and black liquor extraction.

    Key features of belt filter press are:

    Extended gravity dewatering area provides high load capacity and processability at low energy consumption, which reduces operation cost.

    The unique construction of the sloping expanded wedge zone provides stable operation and facilitates processing of heavy volumes of materials.

    Using extrusion rollers with reducing diameter sections allows to obtain a higher solid sludge content in a compact arrangement.

    The unit is equipped with a state-of-the-art automatic deflection and tension correction system, providing trouble-free operation and prolonging the service life of the filter belt. There are two independent backwashing systems

    Advantages

    • Continuous operation: Unlike batch chamber presses, there are no pauses for unloading.

    • Energy savings: due to the absence of high rotation speeds, energy consumption is several times lower than that of centrifuges.

    • Process transparency: the operator always has visibility into the dewatering process and can quickly adjust the chemical dosage or belt tension.

    • Minimal noise: the equipment operates smoothly, without creating strong vibrations in the room.

    FAQ

    What functions does a belt filter press perform, and what is its role in the process chain?

    Its main purpose is to effectively separate suspensions into solid and liquid phases. In practice, this allows for a significant reduction in waste volume, dramatically reducing waste removal and disposal costs. Furthermore, a filter press often helps establish a closed water cycle: the pressed water, after minimal purification, is returned to the process, and the dewatered residue becomes suitable for further processing.

    Is it possible to do without the use of chemicals?

    In 95% of cases, no. To ensure effective water separation, a flocculant must be added to the initial sludge. It collects fine particles into large flocs. Without preliminary preparation, the sediment will simply spread across the belt or pass through it, so properly setting up the reagent dosing system is half the success of the filtration process.

    How difficult is it to maintain such a unit?

    The filter press design is fairly open and intuitive. Primary attention should be paid to the condition of the belts and the proper functioning of their cleaning system. With proper pressure settings and proper alignment, the belt will last a long time, and replacement can be performed by our in-house mechanical service without the need for specialized specialists.
