GNDL303 Screw Press: Dewatering for Municipal Projects

Sludge dewatering remains one of the most important steps in municipal wastewater treatment. With rising disposal costs and increasingly strict environmental regulations, operators are seeking equipment that delivers consistent dryness, minimal maintenance, and dependable performance. GN Solids America is proud to offer the GNDL303 screw press, a system designed specifically with municipal operations in mind.  Unlike traditional centrifuges or belt presses, the screw press operates at a slow rotational speed, applying steady pressure to gradually separate water from solids. This gentle yet effective process reduces energy consumption, lowers noise levels, and minimizes wear on moving components. For municipal plants that must operate continuously, these features translate into lower long-term costs and fewer service interruptions.

The GNDL303 screw press is engineered for reliability and efficiency. Its stainless-steel construction ensures durability in demanding environments, while its enclosed design helps control odors and creates a cleaner operating area. Automation is built into the system, reducing the need for constant operator oversight and allowing staff to focus on broader plant performance.  One of the key advantages of the screw press in U.S. municipal projects is its ability to handle a wide range of sludge consistencies without frequent adjustment. This flexibility supports treatment plants that receive variable influent while still producing a high-quality, dewatered cake suitable for landfill or further processing.As municipalities across the United States modernize their wastewater treatment facilities, GN is committed to supplying proven, cost-effective solutions. The deployment of the GNDL303 screw press represents not just an equipment choice, but a long-term investment in efficiency, environmental compliance, and community infrastructure.
