Mathematical Modeling for Volatile Organic Compounds Removal in a Biofilter: Model Validation and Sensitivity Analysis

Optimal conditions for the biological removal of ammonia from wastewater of a petrochemical plant using the response surface methodology

High concentrations of nitrogen compounds, such as ammonia observed in the petrochemical industry, are the major environmental pollutants. Therefore, effective and inexpensive methods are needed for its treatment. Biological treatment of various pollutants is a low cost and biocompatible replacement for current physico-chemical systems. The use of aquatic plants is an effective way to absorb th...

Development and Validation of a Dynamic Complex Model for Ammonia Removal by Gas-Phase Biofiltration

In this study a general dynamic biofiltration model to describe ammonia removal in a gas-phase biofilter is developed. The mathematical equations are based on discretized mass balances and detailed nitrification kinetics that include inhibitory effects caused by free ammonia (FA) and free nitrous acid (FNA). The model was able to predict experimental results operation under different loading ra...

Dynamic Modelling of a Biofilter Used for Nitrification of Drinkingwater at Low Influent Ammonia Concentrations

This paper reports on the development of a mathematical model of a packed bed biofilter operating at low influent ammonia concentrations. It is initially filled with biomass-free media, the adhesion by filtration of the bacteria present in the groundwater allowing colonization of the filter. The mathematical model is intended for simulation/optimization purposes, and should describe sufficientl...

Mathematical Modeling for Volatile Organic Compounds Removal in a Biofilter: Model Validation and Sensitivity Analysis

In this work, a dynamic model has been developed for prediction of biofilters performance. The model includes most of the phenomena occurring in a biofilter. For biodegradation of pollutants in the biofilm, the Michaelis-Menten kinetic has been considered. The model equations including gas phase and biofilm partial differential equations were solved simultaneously using finite difference and me...
