Sludge Dewatering Screw Press Package Ready for Shippment to Europe Client

GN SOLIDS CONTROL is pleased to announce that a sludge dewatering screw press package is ready for shipment to a European client. The package includes a GNDL303 Screw Press and a GNSJY3000 Chemical Dosing Unit, providing an integrated and automated solution for efficient sludge dewatering and chemical preparation.

The GN GNDL303 Screw Press uses the principle of screw extrusion to achieve solid-liquid separation through the gradual reduction of screw pitch and filtration gaps. During operation, sludge is first concentrated by gravity and then continuously conveyed into the dewatering section, where increasing internal pressure further reduces sludge volume and removes filtrate.

The moving and fixed rings work together to maintain the filtration gaps while the moving rings continuously clean the screen surface, helping prevent clogging and ensuring stable operation. The system is suitable for a wide range of sludge concentrations and offers low energy consumption, compact structure, and easy maintenance.

The GNSJY3000 Chemical Dosing Unit prepares, dissolves, and stores flocculant automatically before delivering the prepared solution to the dosing point. With PLC-based automatic control, corrosion-resistant materials, and integrated preparation, curing, and storage functions, the unit provides reliable and consistent chemical dosing.

This shipment further demonstrates GN SOLIDS CONTROL’s capability to provide customized and integrated sludge dewatering solutions for wastewater treatment applications worldwide.

Complete GNDL302 Screw Press & GNSJY2000 Dosing System Exported for Overseas Sludge Treatment Project

International Business Update — In a new milestone in global environmental equipment export, our company has successfully completed the packaging and shipment of a full-set sludge dewatering system, consisting of the GNDL302 screw press dewatering machine and matched GNSJY2000 chemical dosing unit. The turnkey solution will be delivered to an overseas industrial site to support local sludge harmless treatment, volume reduction and resource utilization work.
Industrial sludge treatment has always been a key and difficult part of wastewater environmental management, with common pain points including low dewatering efficiency, high operating energy consumption and complicated supporting processes. To solve the actual operation problems of overseas clients, our technical team configured a matched combination of core dewatering equipment and automatic dosing equipment for this project, realizing one-stop integrated sludge treatment from chemical conditioning to solid-liquid separation.
The GNDL302 screw press sludge dewatering machine serves as the core processing equipment of the entire system. Adopting advanced low-speed screw extrusion technology, it abandons the vulnerable filter cloth structure of traditional dewatering equipment. The equipment features anti-clogging, low noise and ultra-low power consumption, and is suitable for continuous treatment of municipal sludge, chemical sludge, food processing sludge and multiple types of industrial sludge. Its optimized screw pitch and pressure ring structure can form stable gradient pressure, which efficiently removes free water and capillary water in sludge, greatly reducing sludge moisture content and sludge stacking volume. The whole machine is made of high-strength anti-corrosion stainless steel, adapting to humid and corrosive overseas on-site environments and ensuring long-term stable operation.
Supporting the efficient operation of the main unit is the GNSJY2000 automatic chemical dosing unit, a key supporting facility to improve sludge dewatering quality. The equipment is calibrated according to the rated treatment capacity of GNDL302 screw press, supporting automatic water inflow, chemical proportioning, stirring and quantitative dosing. It can fully mix and react with incoming sludge to promote rapid flocculation and precipitation of fine sludge particles, effectively improving solid-liquid separation effect. The fully automatic integrated design reduces manual intervention, avoids dosing deviation caused by manual operation, greatly improves treatment stability, and reduces on-site operation and maintenance costs.
The combined system of GNDL302 and GNSJY2000 boasts remarkable advantages such as compact overall layout, convenient installation and commissioning, low later maintenance cost and full-automatic unattended operation. It can effectively help overseas enterprises reduce sludge disposal pressure, meet local environmental protection emission and sludge treatment standards, and achieve energy-saving and efficient green production.
This overseas equipment delivery fully demonstrates the company’s strong manufacturing strength and customized solution capabilities in the field of environmental protection sludge treatment. In the future, we will continue to focus on the actual needs of global environmental governance, continuously optimize equipment performance and system solutions, and provide more reliable, efficient and economical sludge treatment equipment and technical services for overseas customers worldwide.
