en.Wedoany.com Reported - NORD Drivesystems, an industrial drive system manufacturer, has launched a modular drive solution covering all key processes in wastewater treatment, focusing on reliability, high performance, and high configurability to reduce downtime and ensure stable system operation.
In the screening stage, the first step in wastewater treatment, NORD-driven mechanical cleaning screens can reduce labor costs, improve water flow conditions, and enhance interception capacity. The MAXXDRIVE XC industrial gear units and parallel shaft gear units used in this stage feature a compact, integrated UNICASE design, offering easy installation, low maintenance costs, and a long service life. The true dry-well design provides additional support and higher operational reliability.
For aeration processes, surface aerators and brush aerators are driven by high-performance MAXXDRIVE industrial gear units and UNICASE parallel shaft gear units to maintain the oxygen supply required for microorganisms to decompose organic matter. These drive units are compact, require minimal maintenance, ensure long-term reliable operation, offer high load capacity, and save costs. Configuration options include advanced sealing systems for leak prevention, high-quality low-friction bearings, and pressure (forced) lubrication systems, with vertical or horizontal mounting options available as needed.
Pumps are the core equipment for wastewater conveyance. NORD gear units are used to optimize pump efficiency, prevent backflow, and ensure smooth transitions between processes. The UNICASE helical gear motors are compact and can be installed in the confined spaces commonly found in pump applications, offering flexible configurations with fine step ratios, various flange or foot mounting options, and 11 housing sizes. Pump drive solutions can also be equipped with IP66 protection ratings, corrosion-resistant surface protection, QUADRALIP sealing systems, and double shaft seals to withstand humid environments and prevent leakage.
The clarification stage improves water quality and ensures compliance with environmental standards by filtering solids, pollutants, and other impurities from the water. NORD gear units for filtration and skimming applications offer high system availability, low maintenance costs, precise control options, and special surface protection options. The UNICASE bevel gear motors and UNICASE parallel shaft gear units are ideal for such applications due to their high efficiency and high axial and radial load capacities.
The sludge thickening process must handle high loads, wear, corrosion, and prevent clogging. NORD provides MAXXDRIVE industrial gear units, UNICASE parallel shaft gear units, and NORDAC PRO frequency inverters for control cabinets for these heavy-duty applications. These gear units can withstand harsh environmental conditions and can be configured with reinforced drive shafts to extend service life and reduce maintenance needs. The frequency inverters precisely control the speed of basin scrapers, effectively increasing solid concentration and reducing free water. They also feature integrated POSICON positioning mode, synchronization functions, and PLCs, enabling energy-efficient operation under partial load or at low speeds to effectively handle various liquid-solid mixtures.
All components of this modular drive solution are manufactured in NORD's own facilities to ensure coordinated operation, unparalleled reliability, long service life, high return on investment, and high configurability.
