The effluents may contain large amounts of harmful organic compounds that are not easily removed with conventional methods. This study focuses on the photocatalytic treatment of four organic pollutants originated from different types of industry. The pollutants are diuron (herbicide), p-coumaric acid (agro-industrial wastewater), bisphenol A and phthalic anhydride (plasticizers), which all are widely used and cause significant health and environmental problems. To get deeper understanding, the photocatalytic degradation of the model molecules was studied both in synthetic solutions and in industrial wastewater matrix over TiO2 P25 in two different batch photoreactors under UV-A irradiation. The effects of catalyst loading, pH and initial concentration were studied. To gain understanding on the reactivity of molecules and costs of treatment, the kinetic modelling and energy modelling were compared and the specific applied energy (ESAE) was estimated. ESAE is proposed as a useful value to estimate the energy needed to degrade one mole of pollutant and further to calculate the operating costs to treat the wastewater. Of the model pollutants, diuron was removed the most efficiently and its removal consumed the least amount of energy in terms of the specific applied energy. Bisphenol A was found to be the most difficult to be removed by photocatalysis. The industrial wastewater matrix affected negatively the removal results.
