WASTEWATER TREATMENT SOLUTION CUTS OPERATING COSTS

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 digitisation of water utilities. With Xylem Edge Control, wastewater operators can 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 managing 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 maximises process control while dramatically cutting energy consumption and supporting sustainability goals.

“Utilities around the world are well on the way to digitising 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 optimise chemical usage and aeration. As utilities target emissions reductions, Edge Control is the latest high-efficiency technology that can help utility companies 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 (PLC) under various communications protocols and connect to existing hardware, including sensors and probes.

Xylem Edge Control combines four solutions. Xylem Edge Control Pulsed Aeration is a digital, energy-saving solution that can prevent the over-aeration of underloaded treatment plants. Xylem Edge Control Ammonia Removal determines a CAS facility’s ammonia target and helps meet its nutrient discharge limits while working to maximise energy savings. Xylem Edge Control Ammonia + Nitrogen Removal offers wastewater utilities the potential to save energy while reducing nitrate and ammonia concentrations. Finally Xylem Edge Control P – Removal controls chemical feed pumps, based on real-time phosphorus concentrations to reduce chemical usage, while meeting today’s stricter phosphorus limits.

The launch of Xylem Edge Control follows rigorous field testing across North America, including Washington and Indiana, including the wastewater treatment operations serving the city of Muncie, Indiana.
