NORD DRIVESYSTEMS provides scalable drive solutions for all steps of the Wastewater Treatment Industry, offering systems focused on reliability, performance, and high configurability to meet precise application needs. With years of experience in the industry, NORD creates modular solutions that reduce downtimes to keep systems up and running smoothly.

High-Efficiency Screening Technology

Screening is the first step of the wastewater treatment process, making it crucial to plant performance. Mechanical cleaning screens automated by NORD result in lower labor costs, better flow conditions, and higher screening capacity. MAXXDRIVE® XC industrial gear units and parallel shaft gear units deliver continuous high efficiency performance that keeps systems running effectively. Their compact, single-piece UNICASE design offers simple installation, low maintenance costs, and a long service life. A true drywell design provides additional support and greater operational reliability.

Optimizing Aeration Processes

Aeration is another important process in wastewater treatment. Surface and brush aerators are integral for the increased supply of oxygen used to feed microorganisms that decompose organic substances and treat pollutants. NORD’s drive solutions for these applications are high performance MAXXDRIVE industrial gear units and UNICASE™ parallel shaft gear units. These drives provide reliable, continuous operation with a compact, low maintenance design that ensures a long service life, high load capacity, and cost savings. Additional configuration options include an advanced sealing system for leak protection, high-quality, low-friction bearings, a pressure (force) lubrication system, and vertical and horizontal alignment options to best fit application requirements.

Compact, Reliable Pump Systems

Pumps play a central role in the transportation of wastewater at treatment plants, acting as the link between the various phases of the purification process. NORD gear units optimize pump efficiency and prevent backups, keeping systems throughout the plant running smoothly and moving water from one process to the next. UNICASE helical inline gear units have a compact design that enables them to easily fit in the tight installation spaces common with pumps. They offer flexible configurations with closely stepped ratios, versatile foot or flange mounting, and 11 case sizes to choose from. Drive solutions for pumps can also be equipped with IP66 ingress protection, corrosion resistant surface protection, a QUADRALIP™ sealing system, and dual shaft sealing rings to protect the system from the wet environmental conditions and prevent leaks.

Clarifying and Filtration Solutions

Clarifying is another crucial part of the wastewater treatment process, filtering solids, pollutants, and other contaminants from the water to improve quality and ensure compliance with environmental standards. NORD gear units for filtration and skimmer applications deliver reliable operation with high system availability, low maintenance costs, precise control options, and special surface protection options. UNICASE helical bevel gear units and UNICASE parallel shaft gear units are ideal for these applications thanks to their efficient performance and high axial and radial load capacity.

Robust Sludge Thickening Control

The process of sludge thickening requires drives that can handle high loads, resist wear and corrosion, as well as prevent blockages. For these heavy-duty applications, NORD offers MAXXDRIVE industrial gear units, UNICASE parallel shaft gear units, and NORDAC® PRO variable frequency drives for control cabinets. These robust gear units withstand tough environmental conditions and can be configured with a reinforced drive shaft extension, offering a long service life and reduced maintenance requirements. NORDAC VFDs precisely control the speed of the basin paddles, effectively increasing the solids concentration and reducing free water. They also feature an integrated POSICON positioning mode and synchronization, an integrated PLC for drive-related functions, and an intelligent energy saving function for optimal operation under partial load or low speeds, handling all types of liquid-solid mixes with ease.

NORD’s modular drive solutions for wastewater treatment are designed to work together seamlessly and feature high configurability for application-specific designs. All components are produced in their own facilities for unsurpassed reliability, long service life, and high return on investment. To learn more about NORD’s wastewater solutions, visit www.nord.com.
