Technology Assessment of the Biological Aerated Filter

摘要

The technology assessment report describes a recently developed biological wastewater treatment concept called the biological aerated filter (BAF)/Biocarbonne process and addresses performance and operational characteristics, design approaches, and potential applications of that process. Recommendations are provided where further definition of process performance response to environmental conditions is felt to be warranted. A brief comparison of the similarities and differences of the BAF/Biocarbonne process with conventional activated sludge is also given. The term BAF is used by the North American vendor of the process, Eimco Process Equipment Company of Salt Lake City, Utah. The Biocarbonne terminology is employed by the original French developer of the technology, Omniun de Traitements et de Valorisation, who markets the process primarily in Europe. Although the process regimes offered by these two companies are essentially identical, distinctly different design approaches have evolved for each.
