Châteauneuf WWTP: regulations and command and control
This spring, we carried out the regulation and command and control of the aeration tanks at the Châteauneuf wastewater treatment plant (WWTP). Mandated by the city of Sion, Telsa reaffirmed its confidence in us by subcontracting our services. HYDRO Exploitation has been involved in water management and treatment since 2016.
Biological treatment is a delicate process
that allows oxygen-fed microorganisms to digest the so-called “activated”
sludge. The flow rate of the water entering the tanks and the levels of injected
CO2 needs to be regulated with the greatest precision in order to
keep the ecosystem alive.
Our Automation & Control engineers
carried out a cascade control on the 4 biological tanks to control:
· 4 suppressors
· 16 air injection valves
· 4 water inlet valves
This automated system has also been
integrated into the touch screen interface and the plant’s monitoring system.
It gives the operator an overall view of the process, which he can control
manually during maintenance, and it notifies him in the event of a fault. Our services also included the electrical
diagram and commissioning.
The client has now a user-friendly
interface and a solution to facilitate future maintenance.
