Modeling wastewater biodecolorization with reactive blue 4 in fixed bed bioreactor by Trametes subectypus: Biokinetic, biosorption and transport

► A biodecolorizaton model with biosorption and biodegradation was developed. ► The biokinetic parameters were determined by fit to Contois model. ► The biosorption parameters were determined by fit to Langmuir model. ► Model predicted Trametes subectypus limits to biodecolorize polluted influent. ► A sorption-reaction dimensionless module (ϕ) is proposed like process criterion.
