Software tool can show when a city’s wastewater treatment will fail

Urban populations and mega-cities are on the rise and so is the amount of wastewater pouring into treatment facilities that cannot adequately handle the load.

What if you had a tool that could tell whether a large wastewater treatment plant was capable of reliably meeting the demand?

“It could avert a public health disaster caused by harmful water quality,” said UWM electrical engineer Lingfeng Wang, who has devised such a software tool.

“For most public systems, there is no quantitative way to know whether operations are working until the output is insufficient,” said Wang, an associate professor of electrical engineering.

Instead of real-time monitoring of the equipment conditions, Wang’s software is based on the historical data on equipment reliability to decide if the existing plant facilities are able to meet the safety requirement on wastewater treatment. Read more…
