Foam separation, an efficient downstream processing unit operation, was tested as a post-treatment technique for phenol removal after biosorption. The biosorptive foam separation process was carried out in two stages, namely biosorption and foam separation. A minimum run resolution V central composite design with four variables (initial concentration, pH, biosorbent dosage, and time) for biosorption and three variables (liquid pool height, surfactant concentration, and air flow rate) for biosorptive foam separation was applied to optimize the process.
