Abstract EN
Olive mill wastewater (OMW) originating from a two-phase olive oil producing plant was treated with a crude polyphenol oxidase (PPO) homogenate, prepared from potato waste peels.
The treatments carried out were based on a 23-full-factorial, central composite design (CCD) in order to identify optimal operational conditions with regard to polyethylene glycol (PEG) concentration, pH, and treatment duration.
The treatment performance was assessed by estimating the % reduction in total polyphenol (TP) concentration.
The model obtained produced a satisfactory fitting of the data (R2=0.96, P=0.0017).
The utilisation of the predictive model enabled the theoretical calculation of the optimal set of conditions, which were pH=4, t=3.57 h, and [PEG] = 900 mg L−1.
Under these conditions, the optimal theoretical % removal calculated was 54±9.
Examination of the treated samples with high-performance liquid chromatography (HPLC) showed that the potato homogenate afforded changes in the polyphenolic profile.
Based on the experimental evidence, oxidation pathways were proposed.
