The principles of biofilter systems, modeling, and operations are quite different from biofilter systems. Because of "biofilter" terminology used in both gas and liquid-phase systems, researchers often mistakenly use gas-phase models in liquid-phase applications for the analysis of data and determining kinetic parameters. For example, recent studies show a well-known biofilter model, known as Ottengraf-Van Den Oever zero-order diffusion-limited model, is applied for analysis of experimental data from an biofilter system which is used for the removal of toxic divalent copper [Cu(II)] and chromium (VI). The objective of this research is to present the limitations and principles of biofilter models and to highlight the incorrect use of gas-phase biofilter models in liquid-phase systems that can lead to erroneous results. The outcome of this work will facilitate scientists and engineers in distinguishing two different systems and selecting a more suitable biofilter model for the analysis of experimental data in determining kinetic parameters.
生物滤池系统的原理、建模和操作与生物滤池系统有很大不同。由于气相和液相系统中都使用了“生物滤池”术语，研究人员经常在液相应用中错误地使用气相模型来分析数据和确定动力学参数。例如，最近的研究表明，一个著名的生物滤池模型，即奥滕格拉夫 - 范登奥弗零级扩散限制模型，被用于分析来自一个用于去除有毒二价铜[Cu(II)]和铬(VI)的生物滤池系统的实验数据。本研究的目的是阐述生物滤池模型的局限性和原理，并强调在液相系统中错误使用气相生物滤池模型会导致错误结果。这项工作的成果将有助于科学家和工程师区分这两种不同的系统，并选择更合适的生物滤池模型来分析实验数据以确定动力学参数。
