MacroFITT® Wastewater Treatment System

MacroFITT® is a scaled-up version of the FAST process that is engineered for the needs of community wastewater with flows in the 200,000 GPD – 2 million GPD range. This system is an advanced wastewater treatment system that uses Fixed Activated Sludge Treatment (FAST) to break down organic material and nutrients in wastewater.

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 system is the main treatment tank, which contains 20-200 fixed-film treatment modules hosting the attached microbes. Air is delivered to each module using blowers for mixing, recirculation, and oxygen transfer within the fixed media beds.

3. Treated effluent leaves the MacroFITT aeration tank and flows through an optional secondary clarifier.

4. The optional Biosolids Management System, or BMS Zone, provides sludge storage and digestion for wasted biosolids transferred from the main treatment tank.
