Wastewater treatment is a critical process that demands robust, reliable, and efficient equipment. NORD DRIVESYSTEMS provides scalable drive solutions designed to meet the precise needs of each stage of the treatment process, from screening to sludge thickening. With years of industry experience and a modular approach, NORD helps plants reduce downtime and maintain smooth, continuous operation.
Screening: The First Line of Defense
Mechanical cleaning screens are essential for removing debris and protecting downstream equipment. NORD’s MAXXDRIVE XC industrial gear units and parallel shaft gear units deliver continuous high efficiency, ensuring systems run effectively. Their compact, single-piece UNICASE design offers:
- Simple installation
- Low maintenance costs
- Long service life
- A true drywell design for additional support and reliability
Automated screens powered by NORD drives result in lower labor costs, better flow conditions, and higher screening capacity.
Aeration: Feeding the Microorganisms
Aeration is vital for supplying oxygen to microorganisms that decompose organic matter. For surface and brush aerators, NORD offers high-performance MAXXDRIVE industrial gear units and UNICASE parallel shaft gear units. These drives provide:
- Reliable, continuous operation
- Compact, low-maintenance design
- Long service life and high load capacity
- Configuration options like advanced sealing systems, low-friction bearings, and pressure lubrication
Pumping: Moving Water Through the Plant
Pumps are the link between treatment phases, and NORD gear units optimize pump efficiency while preventing backups. The UNICASE helical inline gear units are ideal for tight installation spaces common with pumps. They feature:
- Flexible configurations with closely stepped ratios
- Versatile mounting options (foot or flange)
- 11 case sizes to choose from
- Optional IP66 ingress protection, corrosion-resistant coatings, and advanced sealing systems
Clarifying: Filtering Contaminants
Clarification removes solids and pollutants to meet environmental standards. NORD gear units for filtration and skimmer applications deliver:
- Reliable operation with high system availability
- Low maintenance costs
- Precise control options
- Special surface protection options
The UNICASE helical bevel gear units and parallel shaft gear units are ideal for these tasks due to their efficient performance and high axial and radial load capacity.
Sludge Thickening: Handling Heavy Loads
Sludge thickening is a demanding application requiring drives that handle high loads, resist wear and corrosion, and prevent blockages. NORD offers MAXXDRIVE industrial gear units, UNICASE parallel shaft gear units, and NORDAC PRO variable frequency drives. These solutions feature:
- Reinforced drive shaft extensions for long service life
- Precise speed control for basin paddles, increasing solids concentration
- Integrated POSICON positioning mode and synchronization
- Intelligent energy-saving functions for partial load or low speeds
Seamless Integration and Reliability
NORD’s modular drive solutions are designed to work together seamlessly, with high configurability for application-specific designs. All components are manufactured in-house, ensuring:
- Unsurpassed reliability
- Long service life
- High return on investment
From screening to sludge treatment, NORD’s comprehensive portfolio helps wastewater treatment plants achieve operational excellence while meeting environmental compliance goals.
