Replacement of aeration dishes without process interruption

At RWZI Westerlo, Verhoeve Belgium is replacing aeration bulkheads without disrupting treatment processes. Aeration bulkheads are periodically renewed every 8 to 10 years for optimal efficiency.

For installations with multiple aeration basins, this can be done after alternately emptying one basin at a time in dry weather. When only one basin is present, retractable frames are used so that the dishes can be replaced frame by frame. After replacement, a pattern test is first performed at shallow immersion, as shown in our video.

New frames are currently being installed and tested at WWTP Westerlo.
