ABB Variable Speed Drives Improve Energy Efficiency

In the water and wastewater industry, the demand for reliable, energy-efficient solutions is greater than ever. Rising energy costs, environmental regulations, and the need for continuous operation mean that water utilities must find smarter ways to manage their assets. One proven method is the use of ABB Variable Speed Drives (VSDs), which deliver significant energy savings while improving process control.

A VSD controls the speed of an electric motor by adjusting the frequency and voltage of the power supplied. In water and wastewater facilities, this is particularly beneficial for applications such as pumps, blowers, and mixers – equipment that often runs continuously or for extended periods. By matching motor speed precisely to the actual process demand, ABB VSDs eliminate the inefficiencies of running motors at full speed when not required.

Energy Efficiency and Cost Savings
Pumps are one of the largest energy consumers in the water sector. Without a VSD, flow control is often achieved by throttling valves, which wastes energy. ABB VSDs reduce this waste by directly controlling pump speed, typically delivering energy savings of 20–60% depending on the application. Over time, this translates to substantial cost reductions and a lower carbon footprint.

Enhanced Process Control and Reliability
In addition to saving energy, ABB VSDs offer advanced control features that protect critical assets. Soft starting and stopping reduce mechanical stress on pumps and motors, extending their lifespan. Integrated monitoring and diagnostics help identify potential issues before they lead to downtime, ensuring continuous, reliable operation.

Supporting Sustainability Goals
As water utilities face increasing pressure to meet environmental targets, ABB’s energy-efficient drives play a key role in reducing greenhouse gas emissions. They also help facilities qualify for energy-saving incentives, making them a strategic investment.

By integrating ABB Variable Speed Drives into pumping and treatment processes, water and wastewater operators can achieve significant efficiency gains, lower operating costs, and improve the long-term sustainability of their operations.
