Moving Bed Biological Reactor (MBBR) systems are receiving increasing recognition for BNR processes. The primary purpose of these systems is to increase the amount of stabilized biomass within a given biological reactor by introducing independently moving plastic carriers. The technology offers a protected surface for microorganisms to colonize. In this regard, microorganisms acclimatize to a wide range of conditions more readily than conventional suspended phase systems. Because little or no additional tankage is required, these systems are an ideal solution for plants with limited room for expansion. In the spring of 2010, the Town of Oak Creek, Colorado retrofitted its existing treatment system with a post-nitfrication MBBR. A 30 day performance test began in February 2011. During this time the plant tested the MBBR's ability to nitrify at temperatures at or below 5° C. The MBBR system was able to successfully achieve low temperature nitrification and produce an ammonia effluent concentration well below the regulatory permit.
