Optimization of oil removal by sugarcane bagasse using response surface methodology

Oily wastewater is one of the environmental concerns nowadays. The seriousness of oil pollution
problem comes in sync with the expansion of oil exploration and production activities, as well as
industrial growth around the world. In this study, the ability of sugarcane bagasse in removing oil
in synthetic oil wastewater was investigated. Parameters affecting oil removal such as
concentrations of synthetic oil wastewater, biosorbent dosage and contact time were optimized
using Response Surface Methodology (RSM) via Box Behnken Design. Sugarcane bagasse showed
excellent efficiency in removing oil with percentage removal up to 98.73% at 1.3 h contact time
with 3.06 g of biosorbent dosage and 16.9% of synthetic oil wastewater concentration. The use of
sugarcane bagasse in removing oil in water was successfully prove in this study.
