    Working Principle

    The main body of the sludge press is formed by a fixed ring and a floating ring which are mutually contained, and the screw shaft penetrates through it. The small movable filter gap formed between the fixed ring and the moving ring. The inner cavity formed by the screw shaft and the ring are filled with flocculated particles. The end back pressure plate is rotated and compressed to form a sludge cake. The screw shaft rotates and pushes and continuously drives the moving ring to clean the filter gap and prevent clogging. After the sludge is concentrated by gravity in the thickening section, it is transported to the dewatering section. As the general filter gap and pitch gradually become smaller during the advancement process, and under the block of the backpressure plate, great internal pressure is generated, and the volume is continuously reduced to achieve the purpose of sufficient dehydration.

    Screw filter Press
    • Compact structure: easy to carry to any production site and maintenance.
    • Suitable for the dewatering of high and low-concentration sludge.
    • When dewatering low-concentration (2000mg/L) sludge, no need to build thickening tanks and storage tanks.
    • No secondary pollution: reduce the release of phosphorus and the production of anaerobic odor.
    • Replace the filter cloth, self-cleaning, no clogging, easy to treat oily sludge.
