Condren, A. TECHNOLOGY ASSESSMENT OF THE BIOLOGICAL AERATED FILTER. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/2-90/015 (NTIS PB90188806), 1990.
Description:
This technology assessment describes a recently developed biological wastewater treatment concept called the biological aerated filter (BAF)/Biocarbonne process and ddresses 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 quipment Company of Salt Lake City, Utah. he Biocarbonne terminology is employed by he original French developer of the technology, Omniun de Traitements et de Valorisation, who markets the process primarily in Europe. lthough the process regimes offered by these two companies are essentially identical, distinctly different design approaches have evolved for each. hese approaches are described along with an alternative empirical design method proposed by the author of this document based on operating and performance data from several French Biocarbonne systems.
