GN Separation Equipment Manufacturer

This week, GN Separation successfully completed the production of a complete Screw Press Sludge Dewatering System and dispatched it to a European client's site. The order comprises a GNDL303 screw press and a GNSJY2000 polymer dosing unit for sewage treatment.

The Screw Press is the core of the dewatering system, operates on a principle that efficiently separates liquid from solid sludge. This process begins as sludge enters the feed chamber of the screw press, where it is gradually compressed in the augers rotating in a low speed. The augers are designed with a unique spiral shape that creates an increasing pressure gradient along the length of the machine. As the sludge moves through this pressure zone, water is squeezed out, leaving behind a concentrated sludge cake. This mechanical pressing greatly reduces operational costs and environmental impact.

The efficiency of the Screw Press lies in its ability to handle the sludge without the risk of clogging. This versatility makes it suitable for municipal wastewater treatment plants, where sludge characteristics can vary significantly depending on seasonal changes, influent water quality, and treatment processes.

Complementing the Screw Press is the Polymer Dosing Unit, a crucial component in optimizing sludge dewatering performance. The Polymer Dosing Unit prepares and doses flocculants, which are chemicals used to enhance the settling and dewatering properties of sludge particles. By adding a precisely measured amount of flocculant, sludge particles aggregate into larger, more easily separable flocks, thereby improving dewatering efficiency and the quality of the final sludge cake.
The GNSJY2000 unit operates automatically, utilizing advanced controls to monitor and adjust polymer dosage. This ensures consistent treatment outcomes, minimizes polymer consumption, and maintains optimal operational efficiency. The system includes a polymer preparation tank, a dosing pump, and a mixing chamber, all integrated to ensure a seamless flow of flocculant to the screw press.

In sewage treatment, the combination of screw press and polymer dosing unit offers several benefits. Firstly, it significantly reduces the volume of sludge produced, lowering transportation and disposal costs. The dewatered sludge cake is easier to handle and can often be landfilled or used in agricultural applications, promoting circular economy practices. Secondly, the system enhances water recovery, allowing for more efficient reuse of treated water, which is crucial in water-scarce regions. Finally, by minimizing the use of chemicals and energy, the system contributes to a more sustainable wastewater treatment process, aligning with global efforts to reduce environmental footprints.

GN Separation's completion and delivery of this dewatering system demonstrate the company's expertise in providing tailored solutions for sewage treatment challenges. With a focus on innovation, reliability, and sustainability, GN Separation continues to enable clients worldwide to achieve operational excellence and environmental stewardship.
