Wastewater utilities can now achieve compliance targets while cutting energy consumption from aeration by up to 25% with Xylem Edge Control. This off-the-shelf suite of digital solutions for conventional activated sludge (CAS) plants marks the latest breakthrough in the digitization of water utilities. With Xylem Edge Control, wastewater operators can now control and monitor their assets, improve nutrient removal, save energy and reduce costs.

“Wastewater utilities are constantly balancing the need to ensure service reliability and compliance alongside the need to manage costs,” said Chris Taylor, Global Product Manager at Xylem. “Xylem Edge Control helps wastewater utilities confidently walk that line, bringing together our digital innovation expertise and insights from our deep bioprocessing experience, in a suite of solutions that maximizes process control while dramatically cutting energy consumption and supporting sustainability goals.”
“Utilities around the world are well on the way to digitizing their networks and reaping major water, energy and cost efficiencies. Xylem Edge Control is a versatile, multi-functional solution that meets wastewater utilities where they are on that journey – and sets them up to unlock more of the benefits of digital transformation.”
The Edge Control solutions apply analytics to real-time data to provide rapid process recommendations to optimize chemical usage and aeration. As utilities target emissions reductions, Edge Control is the latest high-efficiency technology that can help utilities cut energy-related greenhouse gas (GHG) emissions and make fast progress towards achieving net-zero targets. The platform can operate with any Programmable Logic Controller under various communications protocols and connect to existing hardware, including sensors and probes.
Xylem Edge Control combines four solutions:
- Xylem Edge Control Pulsed Aeration: A digital, energy saving solution that can prevent over-aeration of underloaded treatment plants. Pulsed Aeration improves the overall biological process of CAS plants, to provide adequate mixing and ultimately achieving energy savings. Research and implementation of Pulsed Aeration has shown energy savings of approximately 25% can be achieved.
- Xylem Edge Control Ammonia Removal: Xylem Edge Control Ammonia Removal determines a CAS facility’s ammonia target and helps meet its nutrient discharge limits while working to maximize energy savings. It uses an advanced algorithm to match various load conditions, that can provide consistent ammonia removal and further stabilize the biological process.
- Xylem Edge Control Ammonia + Nitrogen Removal: The solution offers wastewater utilities the potential to save energy while reducing nitrate and ammonia concentrations. It uses an advanced algorithm which communicates with CAS facilities’ existing assets to optimize the achievement of nutrient compliance targets. Its patented, one-of-a-kind, AvN® wastewater treatment process1 has the ability to create a biological environment unlike anything the wastewater treatment industry has seen with its capacity to create a Nitrite shunt. This can allow for an expedited denitrification process and ultimately, increased energy savings. Research and implementation of Ammonia + Nitrogen Removal has shown energy savings of approximately 25% in addition to a reduction in Total Inorganic Nitrogen (TIN) concentration of approximately 30%.
