Are Carrousel® systems large in volume?

Carrousel® systems are designed like any system that operates with CSTR (complete stirred tank reactor) kinetics using common activated sludge modeling software (although Ovivo does use a proprietary model for biological treatment and optimum hydraulics). The long SRT (solids retention time) systems are a thing of the past. Most Carrousel systems are designed at a 6 to 15 day SRT depending on climate and treatment objectives.
