Complete refurbishment of Beauvais wastewater treatment plant


TECH SUB is implementing a complete renewal of the membrane diffusors submerged in the aeration tanks of the Beauvais City WWT. The city wanted to prevent any accidental pollution, after a pollution event occurred in 2017 that impacted the trouts population. The operation consists in cleaning the tanks, and replacing the entire aeration network.
The difficulty of the works is due to the difficult access – the tanks are covered – and the absence of visibility. The works allow to restore the aeration capacity from 30% to 100% without any stop of the process.
