A detailed sensitivity analysis was conducted to identify key parameters for a biotrickling filter simultaneously treating graywater and waste gas containing ammonia and hydrogen sulfide contaminants. Sampling-based approaches were applied to quantitatively assess the sensitivity of both design and intrinsic model parameters. Specifically, the sensitivity of contaminant removal rates under system conditions was investigated. Results suggested that contaminant removal rates can be substantially improved by increasing the fraction of wetted area in a biotrickling filter. Although recirculation flow rate is insensitive when considering liquid contaminant removal, increasing this parameter improves gas removal efficiency and also increases wetted area within the biotrickling filter. Reactor performance can also be improved by increasing gas and liquid residence times. Contaminant diffusivity through the biofilm is an important parameter and should be accurately assessed. This study differentiated key from insignificant biotrickling filter reactor design parameters for the biotrickling filter and provides guidance for similar research applications.read more

Model Development for Biotrickling Filter Treatment of Graywater Simulant and Waste Gas. I
TL;DR: A mathematical model developed to simulate a biotrickling filter capable of simultaneous treatment of graywater simulant and waste gas contaminated with ammonia and hydrogen sulfide was used to make a preliminary assessment on the feasibility of a proposed dual treatment biotickling filter system.

TL;DR: In this article, the authors evaluated the applicability of such a modeling scheme to systems which include a botanical compartment and found that the most sensitive parameters on the transient state behavior were the mass transfer coefficient between gas and solid surfaces, and the fraction of solid surfaces covered by the biofilm; the steady-state response was primarily influenced by the Biofilm specific surface area and the surface area.

Simulation Study on Ammonia Removal in a Biotrickling Filter Using a Steady-state Model
TL;DR: In this article, a simulation study was conducted using a calibrated and validated model for ammonia removal in a cross-flow biotrickling filter, and the relationship of some of the process and design parameters with reactor performance was evaluated.
Modelling the Removal of Airborne Contaminants in Swine Facilities by a Biotrickling Filter
TL;DR: In this paper, the performance of biotrickling filters in reducing emissions of odour and harmful substances from swine facilities was optimized through a modelling study. But, the results of the study were limited to three inocula, i.e., ammonia, dimethyl sulphide and p-cresol.

A comparison of three methods for selecting values of input variables in the analysis of output from a computer code
TL;DR: In this paper, two sampling plans are examined as alternatives to simple random sampling in Monte Carlo studies and they are shown to be improvements over simple sampling with respect to variance for a class of estimators which includes the sample mean and the empirical distribution function.

Factorial sampling plans for preliminary computational experiments
TL;DR: The proposed experimental plans are composed of individually randomized one-factor-at-a-time designs, and data analysis is based on the resulting random sample of observed elementary effects, those changes in an output due solely to changes in a particular input.
