Application of Taguchi experimental design for investigating surfactant enhanced bioremediation of oil contaminated soil

This study was aimed to investigate the influence of five variables (including soil type, surfactant type, surfactant concentration, initial oil concentration, and salinity) on the remediation of oil contaminated soil by using surfactant through the Taguchi experimental design method. The interactions of these five variables were also examined. Each variable was examined with two levels: soil type (loam and sand), surfactant type (rhamnolipid …
