If wastewater treatment plant operators have nightmares, it’s a good bet that many of them have to do with sewage overflows. Few events are as catastrophic for a wastewater facility as a surge of water it can’t process being churned out into the public sphere, in violation of environmental regulations, and to the detriment of public health.
Supervisory control and data acquisition (SCADA) systems are the digital pulse of water and wastewater treatment plants. Serving as the information hub, SCADA makes the most of the day’s cutting-edge technology and in turn uses it to make the most of the plant’s operations. But how to keep up with a system that evolves as quickly as the greatest minds in the field will allow?
Located on the Belgium-Netherlands’ border, the Lanaye Locks link the Albert and Juliana Canals, the latter of which is a side canal of the River Meuse. The three locks are a vital route between Northern and Southern Europe and have operated alongside each other since 1964 but, as two of these are too narrow to accommodate even smaller convoy, the larger lock had over time become a serious bottle neck for canal traffic.

Companies and their employees therefore try to continuously optimize their processes as that is the only way they can remain competitive and deal with increasingly demanding challenges. This white paper offers guidance on the challenges in the individual value creation phases, support tools, how you can become even more productive with networked tools, and tips about which functions can be used and when.

The City of Bloomington’s water purification plant has been operating since 1929. The lime-treated water has high pH which can cause scaling and can eventually clog the piping and filters in the plant. So, the plant needs to re-carbonate the water thereby lowering and stabilizing the pH. CO2 is an effective and safe chemical that offers treatment flexibility for a utility doing pH control.
A landfill operator’s leachate treatment plant in Missouri required pH reduction following lime-softening and prior to the biological wastewater treatment process. Carbon dioxide (CO2) was chosen as a substitute for sulfuric acid due to improved process control and a reduced tendency to form scale.
