“…Bioscrubber consists of two units, a column through which VOC is absorbed from the contaminated stream to the aqueous phase, and a bioreactor in which the biodegradation of VOC compounds takes place. The aqueous phase is recycled to the column after settling of sludge (14). To increase the absorption of hydrophobic compounds, an organic phase (immiscible with water) is added to the aqueous phase.…”

Background: Volatile organic compounds are a major source of air pollution affecting human health and the environment. Different methods are used to remove these pollutants from air streams including conventional and biological methods. Objectives: In this study, the absorption and biodegradation of toluene were examined in a semi-industrial bioscrubber in order to enhance the absorption rate of toluene in the aqueous phase. Methods: The effect of cutting oil was examined as the organic phase. Mass transfer was measured for water only, as well as for three concentrations of cutting oil in water. The growth of microorganisms in the presence of different concentrations of cutting oil was investigated. The microbial consortium was obtained from a wastewater treatment plant in order to inoculate the bioscrubber. First, the ability of the microbial consortium was tested for the degradation of toluene in a bottle. Results: The results showed 98% of toluene in the bottle was degraded by the microbial consortium. In addition, the use of cutting oil significantly decreased kla (from 3.8 to 0.37). Concerning bioscrubber performance, the use of cutting oil as the organic phase increased the efficiency and elimination capacity from 22.5 to 55 and from 34 to 69, respectively, in the case of oil in water. The elimination rate of toluene increased as 32.5% by adding the cutting oil.

“…Parameters that are already well known from previous studies tend to appear near the bottom of the ranked list and are not selected for estimation unless the available data set is very rich in information. These estimability analysis methods have been used to aid parameter estimation in models describing chemical and biological processes 56, 59–65…”

A model is developed to describe thermally‐initiated polymerization of styrene between 100 and 170 °C. The model accounts for generation and consumption of styrene adduct. Chain transfer to adduct is the only transfer reaction used. Autoacceleration is modeled using the break‐point method of Hui and Hamielec. Using formal ranking and parameter selection techniques that account for parameter sensitivity, correlation and uncertainty, 4 of the 40 model parameters are selected for estimation to improve fit between model predictions and data. After estimation, the model predicts conversion data with a standard error of 5%, and provides excellent fit to a MWD curve obtained at 100 °C. Simulation results confirm that high‐temperature degradation reactions are not important in the temperature range of interest.

It selects parameters for estimation based on information about uncertainties in each of the initial parameter values, sensitivity of model predictions to the various parameters, and the quantity and quality of the dynamic experimental data.…”
