FAST Nitrogen Reduction


The MicroFast® was able to successfully complete all requirements of the NSF Standard 40 and NSF Standard 245 (nitrogen reduction) without having to develop a new treatment unit specific for nitrogen reduction. This is largely due to the process that this system uses. The FAST (Fixed Activated Sludge Treatment) process employs a unique hybrid combination of attached and suspended growth in an aerobic packed bed bioreactor. This proven integrated fixed-film activated sludge combination includes the stability of fully submerged, fixed film media and the effectiveness of activated sludge treatment.

The MicroFast® is certified to both the NSF Standard 40 and NSF Standard 245 (nitrogen reduction standard). Based on the review of the executive summary provided by Bio-Microbics, Inc. this system produced an six-month performance average of 3 mg/L CBOD5, 4 mg/L TSS  and 17 mg/L total-nitrogen which is a 55% reduction.
