Rather than using the standard control panel, MMB decided to integrate the te-sewpas controls into the central PLC and Te-Tech provided a functional design specification for this purpose. The project was completed in October 2019. “We’ve been using the air […]

Morpheus was right after all

Intelligent machines are taking over (wastewater treatment at least). Stuart Rice assesses the use of Artificial Intelligence in control systems for Wastewater Treatment Works. The release of the fourth movie in the Matrix series, Matrix Resurrections, seems like an appropriate time to look at how machines with artificial intelligence are taking over many process control […]
