Sludge Dewatering Screw Press Package for South America Client

GN Solids America recently delivered a complete Sludge Dewatering Screw Press Package for a South America client, providing an efficient and easy-to-operate solution for municipal and industrial sludge treatment. The package mainly consists of a GNDL202 Screw Press and a GNZJY1000 Chemical Dosing Unit, designed to improve dewatering performance while reducing operating and maintenance complexity.

The core equipment, GNDL202 Screw Press, adopts a continuous low-speed extrusion dewatering principle. Sludge is gradually concentrated and dewatered through a series of fixed and moving rings, while the screw shaft increases pressure step by step toward the discharge end. This working principle allows stable operation with low noise and minimal vibration. Compared with traditional dewatering equipment, the screw press runs at a much lower speed, which significantly reduces wear and energy consumption, making it suitable for long-term continuous operation.

Another key advantage of the GNDL202 screw press is its simple operation and maintenance. The self-cleaning ring structure effectively prevents clogging, even when handling oily or fibrous sludge. Daily operation requires minimal supervision, and routine maintenance is straightforward, helping clients reduce labor costs and downtime. The compact design also saves installation space, which is especially beneficial for retrofit projects.

To ensure optimal dewatering results, the system is equipped with the GNZJY1000 Chemical Dosing Unit. This automatic dosing system prepares and matures polymer flocculants at the required concentration, ensuring consistent flocculation performance. The dosing unit integrates powder feeding, solution preparation, aging, and precise dosing into one automated process. By maintaining stable polymer concentration, it improves sludge floc formation, enhances water separation efficiency, and reduces chemical consumption.

This screw press dewatering package is widely used in municipal wastewater treatment plants, food processing, chemical industry, pulp and paper, and other industrial sludge treatment applications across South America. With reliable performance, low operating cost, and high automation level, GN Solids America continues to provide cost-effective and environmentally friendly sludge dewatering solutions to global clients.
