1. The first compartment acts as a primary clarifier by default. It can be upgraded with the Aeration Management System (AMS) Zone pre-aeration option, which contains LIXOR® pre-aeration devices. The outlets of the first compartment contain SaniTEE screens to hold back larger solids.
2. The second part of the treatment train is the main treatment tank, which contains 20-200 liners (fixed-film treatment modules) hosting the attached microbes. This treatment tank is also strongly aerated. Air is delivered to each module for mixing, recirculation, and oxygen transfer within the fixed media beds.
3. The optional Biosolids Management System, or BMS Zone, provides sludge storage and digestion for wasted biosolids transferred from the main treatment tank.
