In the sugar production industry, the processing of beetroot generates substantial wash water containing soil, organic matter, and other impurities. Efficient treatment of this wastewater is critical to meet environmental regulations and optimize resource recovery. Gn’s GNLW764 centrifuge emerges as an ideal solution, combining advanced mechanical principles with high-performance dehydration capabilities to address the challenges faced by European sugar factories.
The GNLW764 centrifuge features a robust horizontal design with a 760mm drum diameter and a maximum rotational speed of 2,650 rpm. Its high-speed rotation generates a centrifugal force exceeding 3,000 G, enabling rapid separation of solid particles from liquid phases. The centrifuge operates on a continuous-feed principle: contaminated wash water enters the rotating drum, where solids are forced outward against the drum wall, while clarified water flows toward the center for discharge.
A key innovation lies in the helical conveyor system, which rotates slightly slower than the drum. This differential speed (controlled by a precision gearbox) ensures efficient scraping and transport of separated solids toward the discharge ports. The centrifuge’s large length-to-diameter ratio enhances retention time, improving separation efficiency for fine particles common in beetroot wash water.
The GNLW764 excels in moisture reduction through a multi-stage process. After initial sedimentation in the drum, solids undergo compression in the tapered section, where mechanical squeezing further expels residual water. The adjustable weir plates allow operators to fine-tune the liquid level, optimizing the balance between dryness and recovery rate. Tests show the centrifuge achieves over 90% solid capture with dewatered sludge containing less than 30% moisture—critical for reducing disposal costs.
At a European sugar plant, three GNLW764 units were deployed to handle 150 m³/hr of wash water. Results demonstrated:
Efficiency: Removal of 98% suspended solids, meeting EU discharge standards.
Energy Savings: The centrifuge’s optimized hydraulic system reduced power consumption by 15% compared to traditional decanters.
Durability: Tungsten carbide-coated components resisted abrasion from sandy particles, minimizing maintenance downtime.
The centrifuges also contributed to sustainability by enabling water reuse in washing cycles, cutting freshwater consumption by 40%. Real-time PLC monitoring ensured stable operation, with vibration sensors triggering automatic adjustments to prevent imbalance.
Guanneng’s GNLW764 centrifuges have proven indispensable for European sugar producers, merging technical excellence with environmental stewardship. Their ability to deliver consistent, low-moisture sludge and clear effluent underscores the value of advanced separation technology in industrial wastewater management. As sugar factories increasingly prioritize circular economy principles, such innovations will continue to redefine efficiency in the sector.
