AquaFAS™

Product Description

AquaFAS^TM is an integrated fixed-film activated sludge (IFAS) treatment process in which our MBBR biofilm carrier technology is incorporated with conventional suspended growth activated sludge. The hybrid process enhances volumetric productivity without increasing mixed liquor suspended solids (MLSS) concentrations. In doing so, it achieves high levels of performance in small footprints while reducing the impact of solids loading on the clarification process. AquaFAS^TM is an ideal low-cost retrofit solution for conventional activated sludge systems that are at or beyond capacity. Its small footprint and high-performance nitrification/denitrification capability also make it well suited for new construction applications.

Process Advantages

Enhances the Conventional Activated Sludge Process
The AquaFAS^TM (IFAS) process will operate just like an activated sludge process but with improved:

Response to shock loading or toxic shock
Cold temperature performance, especially for nitrification
Resistance to filamentous overgrowth and sludge bulking
Sludge settling characteristics
Oxygen transfer efficiency (biofilm carriers serve as a shearing device)
Retention of nitrifying organisms (reside on biofilm carriers)
Total nitrogen removal

Increase Existing Plant Capacity & Performance

In most cases, it is possible to double the hydraulic capacity of your existing activated sludge reactor(s) or convert a secondary treatment plant to a nitrification/denitrification plant for < $1 per gallon treated with an IFAS upgrade.

Superior Nitrification & Denitrification
The IFAS process is specifically designed to enhance nitrification and denitrification. The biofilm carrier surface area provides an ideal environment for autotrophic organisms that are the backbone of the nitrification and denitrification process.

Reduced Clarifier Loading

By achieving a high-density population of fixed-film bacteria within the activated sludge process, mixed liquor (MLSS) levels are lower in relation to treatment productivity; clarifier performance is optimized by reducing the solids load generated from the secondary biological process.
