The McBride site, specialized in detergent manufacturing, approached our partner APUMAS with an uncommon and technically challenging situation. The treatment plant had a covered buffer tank of 18 meters accessible only through a single opening of 80x110cm at the edge of the tan, and no possibility to carry out civil works. It had only one undersized mixer that provided insufficient mixing and no aeration, resulting in numerous failures in in addition to recurring smell problems.
Additionally, the client did not want to empty the tank and sought a solution that could combine aeration and mixing or just mixing.
The ballast-mounted AER-SL aerator-mixer was the ideal product. Apumas also provided an electrical cabinet connected to the mixer and aerator so that the equipment could operate optimally at all water levels (1 to 4 meters) in both aeration and mixing modes. A foam level sensor was installed to prevent risks of overflow.
The result after 2 months was unanimously positive. The tank is fully mixed, and old sediments have been put back in suspension throughout the tank thanks to the powerful mixing capacity. The variable aeration capacity settings work perfectly. Moreover, the AER-SL demonstrated its compatibility with detergent-loaded effluents by not triggering the level sensor any single time.
