The MicroFAST wastewater treatment system from Bio-Microbics is available for 500 to 9,000-plus gpd applications. The system is integrated into a standard septic tank and does not require additional space. Alternate modes of operation include recirculation of nitrified wastewater to the primary settling chamber for denitrification and an SFR feature that allows intermittent operation of the blower to reduce electricity usage up to 45 percent and improve nitrogen performance. It is alternate, advanced treatment with high levels of nitrogen removal. The effluent meets secondary quality requirements and can be distributed to soil treatment system or water reuse applications. 800/753-3278; www.biomicrobics.com.
