Bioslurry phase remediation of chlorpyrifos contaminated soil: Process evaluation and optimization by Taguchi design of experimental (DOE) methodology

Effect of Co‐culture and Nutrients Supplementation on Bioremediation of Crude Petroleum Sludge

“…Further, the presence/ absence of indigenous activity significantly govern the overall bioremediation process efficiency [35]. Biodegradation of real field petroleum sludge was studied anaerobically and the degradation was found to be influenced by applying bioaugmentation, biostimulation and co-substrate addition.…”

Optimization of hybrid PVD process of TiAlN coatings by Taguchi method

“…Among the DOE methods, Taguchi method is becoming a popular one for industrial application due to its efficiency and convenience. The Taguchi method not only helps in considerable saving of time and cost, but also leads to a fully developed process and provides systematic, simple and efficient approach for the optimization of the process parameters [17][18][19]. DOE methodology by Taguchi orthogonal array (OA) is a factorial-based approach which merges statistical and engineering techniques.…”

Remediation of Salt- and Petroleum Hydrocarbon- Contaminated Soils using Ultrasound and Soil Washing.

“…The effects of interactions among multiple factors and the influence of individual factors on system performance can be effectively investigated by applying this technique (Ghani et al, 2004;Venkata Mohan et al, 2007). Analyses of the experimental data using signal-to-noise (S/N) ratio analysis and ANOVA can provide information about statistically significant factors and the corresponding optimal levels for each factor (Venkata Mohan et al, 2007).…”

“…It has also been widely applied to environmental engineering studies. For example, Madaeni and Koocheki (2006) reported with positive results for optimization of a wastewater treatment system by using Taguchi method; Venkata Mohan et al (2007) used Taguchi method to design experiments to evaluate the influence of biotic, abiotic Page 41 and several other factors on soil bioremediation in bioslurry phase reactor. Some other related studies using Taguchi design method can be found in Urum et al (2003), Castorena-Cortes et al (2009).…”

“…Three different flow rates were selected in the experiments including 0.5 cm 3 /s, 1.0 cm working conditions for the remediation process, orthogonal experiments were designed and utilized. The orthogonal experimental design is based on Taguchi method and used to determine the optimal process parameters and analyze the effects and significances of different parameters through least number of experiments (Ross, 1996;Venkata Mohan et al, 2007). Table 3.2 presents the results of Taguchi experimental design.…”
