A steady-state model presented by Boltz, Johnson, Daigger, and Sandino (2009) describing integrated fixed-film activated sludge (IFAS) and moving-bed biofilm reactor (MBBR) systems has been demonstrated to simulate, with reasonable accuracy, four wastewater treatment configurations with published operational data. Conditions simulated include combined carbon oxidation and nitrification (both IFAS and MBBR), tertiary nitrification MBBR, and post denitrification IFAS with methanol addition as the external carbon source. Simulation results illustrate that the IFAS/MBBR model is sufficiently accurate for describing ammonia-nitrogen reduction, nitrate/nitrite-nitrogen reduction and production, biofilm and suspended biomass distribution, and sludge production.
由博尔茨、约翰逊、戴格尔和桑迪诺（2009年）提出的一个稳态模型，用于描述一体化固定膜活性污泥（IFAS）和移动床生物膜反应器（MBBR）系统。该模型已被证明能够以合理的准确度，根据已发表的运行数据模拟四种废水处理配置。模拟的条件包括碳氧化和硝化联合作用（IFAS和MBBR均适用）、三级硝化MBBR以及添加甲醇作为外部碳源的后置反硝化IFAS。模拟结果表明，IFAS/MBBR模型在描述氨氮还原、硝酸盐/亚硝酸盐氮还原与生成、生物膜和悬浮生物质分布以及污泥产量方面足够准确。
