Water utilities are responsible for providing clean and safe water in our cities and communities. With mounting regulatory pressures and the growing demand for sustainable operations, water and wastewater facilities use advanced technologies to optimise their processes.
Motor control solutions are pivotal in maintaining efficient operations in this industry. From reducing energy consumption to improving the lifespan of critical equipment, motor control systems like those from IPD support the water and wastewater sector.
What are Motor Control Solutions?
Motor control solutions regulate and manage pumps, blowers, and compressors, which are key components of water treatment and distribution processes. IPD’s motor control solutions include ABB’s Variable Speed Drives (VSDs), Universal Motor Controllers (UMCs), Soft Starters, and Electric Motors. Each product is designed to ensure precise control and protection across different applications.
For example, VSDs optimise motor performance by adjusting the motor speed to meet the specific demands of the application. Meanwhile, soft starters gradually increase the voltage to prevent excessive mechanical and electrical stress during startup. This functionality is necessary for sensitive water applications such as pumping stations, where abrupt starts can cause equipment failure or inefficiency.
Key Benefits of Motor Control Solutions to the Water & Wastewater Sector
- Improved Energy Efficiency
Energy consumption accounts for a significant portion of operational costs in water utilities. Motor control solutions, such as VSDs, help reduce energy usage by adjusting motor speeds to meet real-time demand.
For instance, a VSD can increase or decrease motor output to align with water flow requirements in pumping systems and minimise energy waste. Lowering power consumption reduces operational costs and contributes to more sustainable practices.
- Reduced Downtime & Maintenance Costs
Unexpected equipment failures in water utilities can lead to costly downtime and disrupt service delivery. ABB’s soft starters and UMC’s address this issue by providing soft starts and protective functions that reduce mechanical wear and tear on motors.
UMC’s also enables predictive maintenance, continuously monitoring the motor's health and providing real-time diagnostic data. This proactive approach helps prevent costly unplanned outages.
- Operational Flexibility
The water and wastewater often require flexible motor control systems to handle varying operational demands. UMC’s allow operators to remotely monitor and adjust motor performance to match fluctuating water usage patterns.
This capability is particularly useful in aeration systems, where air delivery rates must be precisely controlled. With intuitive control systems, motor performance can be optimised for maximum efficiency and responsiveness.
- Application-Specific Performance
Whether managing high-demand pumping stations or delicate aeration systems, ABB motor control solutions are engineered for application-specific performance.
For example, precise control is required in dewatering systems to avoid overloading the pump or draining too quickly. ABB VSDs offers this level of precision by maintaining consistent motor performance across varying conditions.
Practical Applications in the Water & Wastewater Sector
Motor control solutions have broad applications in the water and wastewater industry:
- Pumping Systems
Pumping stations are critical for moving water through treatment facilities and distribution networks. VSDs allow water utilities to adjust pump speed to match demand, thereby reducing energy consumption and minimising wear on equipment.
- Dewatering Systems
A dewatering system removes excess water from sludge or other materials. Precise motor control is necessary to manage the flow and efficiency of the dewatering process. Soft starters help gradually increase motor speed (from zero to full speed), reducing mechanical strain and extending the dewatering equipment's lifespan.
- Aeration
Aeration systems introduce oxygen into water to break down organic matter in wastewater systems. UMC’s ensure optimal airflow delivery and energy efficiency during this process.
Real-Life Impact of Motor Control Solutions on Water Facilities
One notable example of how ABB motor control solutions enhance efficiency, and sustainability comes from a project with Albury City Council’s water plant in New South Wales. The water plant faced challenges with aging infrastructure that wasn’t operating efficiently, coupled with electrical disturbances affecting nearby residential areas.
ABB’s ACQ580 ultra-low harmonic (ULH) VSDs and M2BAX IE3 premium efficiency motors were installed to address these issues. The ACQ580 ULH VSDs provided precise control over the motor speed, allowing the plant to reduce energy consumption by adjusting motor operation to optimal levels. The ultra-low harmonic nature of these drives helped mitigate the electrical disturbances (harmonic content) that had previously been causing problems for nearby homes.
Beyond the expected energy savings, the VSDs offered various additional benefits, including smoother motor operation and reduced wear and tear, which has prolonged equipment lifespan and lowered maintenance costs.
