“…In order to assess the effect of supported catalysis on biodegradability, the biological oxygen demand (BOD5) and chemical oxygen demand (COD) values were measured after 60 min of electrolysis on the modified electrode and the BOD5/COD ratio was used as a biodegradability indicator [30,31].…”

“…Substances used as herbicides (metobromuron, isoproturon, etc.) or in the manufacture of dyes, such as 5-amino-6-methyl-2-benzimidazolone (AMBI) are biorecalcitrant molecules, while compounds, such as benzalkonium chloride are bactericides [111][112][113][114]. The combination of biological method with heterogeneous photocatalysis can be used to reduce the biorecalcitrance or the toxicity to bacteria to a level that permits the biological treatment.…”

Heterogeneous photocatalysis is a process of great potential for pollutant abatement and waste treatment. In order to improve the overall performance of the photoprocess, heterogeneous photocatalysis is being combined with physical or chemical operations, which affect the chemical kinetics and/or the overall efficiency. This review addresses the various possibilities to couple heterogeneous photocatalysis with other technologies to photodegrade organic and inorganic pollutants dissolved in actual or synthetic aqueous effluents. These combinations increase the photoprocess efficiency by decreasing the reaction time in respect to the separated operations or they decrease the cost in respect of heterogeneous photocatalysis alone, generally in terms of light energy. Depending on the operation coupled with heterogeneous photocatalysis, two categories of combinations exist. When the coupling is with ultrasonic irradiation, photo-Fenton reaction, ozonation, or electrochemical treatment, the combination affects the photocatalytic mechanisms thus improving the efficiency of the photocatalytic process. When the coupling is with biological treatment, membrane reactor, membrane photoreactor, or physical adsorption, the combination does not affect the photocatalytic mechanisms but it improves the efficiency of the overall process. The choice of the coupling is related to the type of wastewater to be treated. A synergistic effect, giving rise to an improvement of the efficiency of the photocatalytic process, has been reported in the literature for many cases.

“…activated sludge, biofilm reactors) can help to improve the cost efficiency of a high effective process. The effectivity of the coupled process is usually recorded using time evolution of coarse concentration variables such as total organic carbon (TOC), chemical oxygen demand (COD), biochemical oxygen demand (BOD) or some of their relationships (Esplugas et al, 2004;Sarria 2003;Pulgarin et al, 1999). Relatively few works on the application of this kind of coupled methodologies are available in literature.…”
