This week, GN Separation completed the assembly of four GNLW224 decanter centrifuges along with their corresponding polymer dosing units at its manufacturing facility. The equipment is scheduled for final inspection and acceptance testing by an overseas client next week.
The GNLW224 is the smallest-capacity model in GN Separation’s decanter centrifuge lineup for wastewater treatment applications. Engineered for reliable performance in compact installations, the unit operates at a maximum rotational speed of 5,000 RPM, enabling efficient solid–liquid separation across a wide range of industrial and municipal wastewater streams.
Each centrifuge is equipped with a 3-variable-frequency-drive (VFD) control cabinet, allowing operators to fine-tune key parameters—such as bowl speed, differential speed, and feed pump flow rate—to optimize separation efficiency based on specific sludge characteristics and process requirements.
To further enhance treatment performance, the centrifuges are integrated with GN Separation’s polymer dosing units, which precisely deliver flocculating agents into the wastewater stream. Proper chemical conditioning improves particle aggregation, significantly increasing separation efficiency and producing clearer effluent. The synchronized operation between the decanter centrifuges and dosing systems enables higher solid recovery rates, reduced downstream processing loads, and minimized environmental impact.
Designed with a compact footprint, the GNLW224 can be easily incorporated into existing plant layouts without extensive civil or structural modifications—an important advantage for facilities upgrading older equipment or increasing capacity within limited space. Its robust construction, featuring corrosion-resistant materials and wear-protected components, ensures stable, long-term operation even in challenging conditions such as high-temperature or abrasive sludge environments.
During the upcoming client inspection, GN Separation’s technical team will conduct comprehensive testing of the assembled units, including verification of rotational speeds, water flow rates, vibration limits, and main bearing temperature rise. The team will work closely with the client’s engineers to validate system performance and discuss integration with the client’s existing treatment infrastructure.
As global demand for compact, energy-efficient wastewater treatment solutions continues to grow—driven by increasingly stringent environmental regulations and rapid industrial expansion—GN Separation is well positioned to meet market needs. The GNLW224 offers a cost-effective alternative to larger and more complex systems, delivering strong separation performance while minimizing installation and operating costs. With production capacity now accelerating to support rising demand, GN Separation continues to strengthen its presence in the global wastewater treatment equipment market.
