In a significant advancement for the wastewater treatment industry, GN Separation has recently completed the manufacture of a GNDL402 Sludge dewatering screw press and a set of chemical dosing unit, which will be delivered to a European client.

The sludge dewatering screw press is a key component in modern wastewater treatment plants, distinguished by its compact design, energy efficiency, and high degree of automation. It is designed to efficiently separate solids from liquids in sludge, reducing its volume and improving its handling characteristics. Central to its effectiveness are two 400mm diameter dewatering screws, which efficiently extract moisture from the sludge, significantly lowering its water content.

The screw press comprises a drive module, a screw dewatering assembly, a flocculation adjustment chamber, and an electronic control panel. This configuration ensures a continuous and automated process from material reception through sludge conditioning to final dewatering.

Enhancing the performance of the sludge dewatering screw press is the chemical dosing unit for flocculation of solids, it’s a crucial component in optimizing the dewatering process. This device automatically adds the necessary chemicals to the sludge, improving its flocculation properties and thereby increasing the efficiency of solid-liquid separation. The automated dosing system ensures precise chemical ratios and contributes to a more streamlined and cost-effective operation.

With its compact size, energy efficiency, and high degree of automation, the sludge dewatering screw press is ideal for facilities with limited space or resources. Beyond their practical benefits, these machines also support environmental sustainability. By effectively reducing sludge volume and improving handling, they facilitate the recycling and reuse of waste materials, aligning with global efforts to promote circular economy practices.

GN Separation continues to expand its international presence. For more information on the GN sludge dewatering screw press unit, please feel free to contact us.
