Emerging Technologies Bioaugmentation updated 2012 March 2013 Technology Summary Bioaugmentation (continued) Regeneration-DeNitrification (R-DN) Process: The R-DN process is identical to BAR process and involves filtrate or centrate bioaugmentation. It was independently developed in the Czech Republic and the United States. Centrate and RAS Reaeration Basin (CaRRB) Process: Another named process that is identical to the BAR and R-DN processes. Comparison to Established Technologies: Bioaugmentation processes can be used to reduce the bioreactor volume of many mainstream treatment processes. In general they reduce the loading to the mainstream plant by pretreating the high-strength recycle flow while providing the mainstream plant with seed organisms generated in the sidestream reactor. Depending on the needs of the mainstream process, the sidestream process can be configured to augment populations of both nitrifiers and denitrifiers. The biomass generated by the sidestream reactor allows the mainstream reactor to be smaller in volume while providing the required SRT. The reduction in required volume can allow a portion of the basin volume to be converted to provide denitrification or phosphorus removal. By pretreating the sidestream before blending into the mainstream process, loading and performance can be stabilized. Available Cost Information: Approximate Capital Cost: Cost information is not available from vendors. However, bioaugmentation processes save capital costs in the main treatment systems because of reduced reactor volumes via the augmentation of nitrifying bacteria. Approximate O&M Costs: The operating costs are mainly related to mixing and aeration requirements and depend on local conditions and the available equipment. Bioaugmentation processes also save operating costs in the main treatment through the augmentation of nitrifying bacteria. Actual costs were not disclosed.
