GN Separation has recently fulfilled a successful equipment delivery for an overseas client, covering a full set of sludge dewatering equipment and automatic chemical dosing units. The shipped equipment, including GN screw press sludge dewatering machines and matched chemical dosing systems, will be deployed to the client’s industrial sludge treatment project. It is expected to significantly boost sludge dewatering efficiency, optimize overall treatment processes, and cut long-term operational costs for the project.
GN Screw Press Sludge Dewatering Machine
The GN screw press sludge dewatering machine is a cost-effective, eco-friendly solution tailored for diversified sludge treatment scenarios. Adopting a mature screw extrusion solid-liquid separation principle, the equipment achieves continuous sludge thickening and deep dewatering through the powerful extrusion force generated by variable screw diameters and pitches, combined with the precise micro-gap filtration between fixed and moving rings.
Outperforming conventional sludge dewatering equipment, the GN screw press features low power consumption, fully automated operation, stable running performance, and simple daily maintenance. Its versatile adaptability enables wide application in municipal sewage treatment, industrial wastewater treatment, oily sludge disposal, food processing, chemical production and other industries.
The complete GN screw press dewatering system comprises a full-automatic control cabinet, flocculation conditioning tank, integrated sludge thickening and dewatering unit, and filtrate collection tank. Equipped with advanced intelligent control technology, the system supports automatic flocculant preparation and uninterrupted continuous dewatering operation. The treated filtrate can be either recycled for reuse or discharged up to standard, complying with diverse project environmental requirements.
Automatic Polymer Chemical Dosing Unit
Supporting the screw press dewatering system, GN Separation also delivered a customized automatic chemical dosing unit, which is professionally designed for continuous, efficient and stable polymer chemical preparation and dosing. The entire unit is constructed of high-quality stainless steel and adopts a three-chamber integrated structure, including independent preparation, curing and storage compartments to ensure graded and thorough chemical dissolution.
The unit features simple and intelligent operation. On-site operators only need to add dry powder chemicals to the preparation tank and start the system. The chemical-water mixture first enters the stirring and dissolving chamber for full homogenization, then flows into the curing chamber for sufficient maturation to stabilize chemical activity, and finally transfers to the storage chamber. The well-prepared chemical solution can be automatically and quantitatively delivered to the dosing points via supporting dosing pumps.
This automated dosing system effectively reduces manual intervention and labor costs, improves the efficiency and accuracy of polymer preparation, and maintains consistent dosing stability throughout the sludge treatment process, laying a solid foundation for standardized and high-efficiency sludge dewatering.
