Shaftless Screw Press Filter Screen - High-Efficiency Dewatering Solutions from China Suppliers and Factory

Our advanced screening system, designed for optimal solid separation, begins with a robust screen that effectively retains solids. Equipped with specialized brushes on the outer diameter of the flighting, the internal screen surface remains continuously clean as water flows through. This innovative design allows the shaftless spiral to transport solids up to the compaction module, where further dewatering occurs. Depending on the material characteristics, our technology can reduce screenings by over 50% of their original volume. As a leading factory in China, we are proud to supply high-quality solutions that enhance efficiency and performance for our clients.

    Product Detail

    Product Description

    This kind of SCREEN offers the waste water filtration and the transport of the effluents for the stocking, in a practical and efficient package. The machine can be installed inclined (between 35 ° and 45 ° depending on the needs) into a concrete channel or in a stainless steel tank to receive the wastewaters from a fixed pipe.
    SCREW SCREEN COMPACTOR Feature: The SCREW SCREEN COMPACTOR is the more complete variant, with a compactor zone next to the discharge, which allows an important reduction in weight and volume of filtered waste (up to 50% less).

    Filtration Zone

    The filtration zone for all the variant of the SCREW SCREEN is made up by a holed sheet (circular holes from 1 to 6mm) which filters the wastewater holding back the waste. Into this zone, the shaftless screw is equipped with brushes for the cleaning of the filtration. There is also a washing system activatable by a manual valve or through solenoid valve (optional).

    Transport Zone

    The transport zone is composed by an auger and the continuation of the shaftless screw. The screw, when activated by gear motor, rotates on itself picking and transporting waste until the discharge outlet.

    Applications

    This is a kind of advanced solid-liquid separation device in water treatment, which can continuously and automatically remove debris from wastewater for sewage pretreatment. It is mainly used in municipal sewage treatment plants, residential quarters sewage pretreatment devices, municipal sewage pumping stations, waterworks and power plants, also it can widely be applied to water treatment projects of various industries, such as:
    Textile Printing & Dyeing Food Industry Fishery Paper Mills Wine Production Butchery Curriery

    Frequently Asked Questions

    What is a Screw Screen Compactor?

    It is an advanced solid-liquid separation machine that combines wastewater filtration, transport, and compaction in a single unit, reducing the weight and volume of filtered waste by up to 50%.

    How is the Screw Screen installed?

    The machine can be installed at an incline of 35° to 45° depending on site requirements, either directly into a concrete channel or inside a stainless steel tank.

    What is the filtration range of the screen?

    The filtration zone features a holed sheet with circular hole options ranging from 1mm to 6mm to effectively filter out different sizes of debris.

    How does the self-cleaning system work?

    The shaftless screw is equipped with brushes in the filtration zone to clean the screen automatically. Additionally, a washing system can be activated manually or via an optional solenoid valve.

    Where is this equipment commonly applied?

    It is widely used in municipal sewage treatment plants, residential quarters, pumping stations, waterworks, power plants, and industrial wastewater treatment in sectors like food, textile, paper, and fishery.
