“…In this way, other AOPs can be used as pre-treatment in order to remove aromatic compounds, toxic to many microorganisms and after subject to biological process. Lucas et al [43] first evaluated the COD degradation level to the biological process individuality. Since it was not possible to achieve the desired COD reduction, it was evaluated the Fenton reagent and its combination with biological treatment.…”

Agro-industrial wastewaters are characterized by the presence of multiple organic and inorganic contaminants of environmental concern. The high pollutant load, the large volumes produced, and the seasonal variability makes the treatment of these wastewaters an environmental challenge. A wide range of wastewater treatment processes are available, however the continuous search for cost-effective treatment methods is necessary to comply with the legal limits of release in sewer systems and/or in natural waters. This review presents a state-of-the-art of the application of advanced oxidation processes (AOPs) to some worldwide generated agro-industrial wastewaters, such as olive mill, winery and pulp mill wastewaters. Studies carried out just with AOPs or combined with physico-chemical or biological treatments were included in this review. The main remarks and factors affecting the treatment efficiency such as chemical oxygen demand (COD), biochemical oxygen demand (BOD5), total organic carbon (TOC), and total polyphenols removal are discussed. From all the studies, the combination of processes led to better treatment efficiencies, regardless the wastewater type or its physico-chemical characteristics.

“…Gomec et al [21] applied Fenton's oxidation to OMW after acid cracking and cationic polyelectrolyte treatment while BeltranHeredia et al [9] and Lucas et al [22] combine Fenton's reagent with aerobic biological treatment. Treatment of olive mill wastewater was also studied by Fenton reagent [23] and by a combined process: Fenton's reagent and chemical coagulation.…”

This work presents the application of Fenton's reagent process combined with anaerobic digestion to treat an olive mill wastewater (OMW). Firstly, OMW was pre-treated by chemical oxidation in a batch reactor with Fenton's reagent, using a fixed H2O2/COD ratio of 0.20, pH = 3.5 and a H2O2/Fe(2+) molar ratio of 15:1. This advanced oxidation treatment allowed reaching reductions of 17.6 and 82.5% of chemical oxygen demand (COD) and total polyphenols (TP), respectively. Secondly, OMW treatment by anaerobic digestion was performed using previously adapted microorganisms immobilized in Sepiolite. These biological tests were carried out varying the substrate concentration supplied to the reactor and COD conversions from 52 to 74% were obtained. Afterwards, Fenton's reagent followed by anaerobic digestion was applied to OMW treatment. This combined process presented a significant improvement on organic load removal, reaching COD degradations from 64 to 88%. Beyond the pollutant load removal, it was also monitored the yield of methane generated throughout anaerobic experiments. The methane produced ranged from 281 cm(3) to 322 cm(3) of CH4/g COD removed. Additionally, a methane generation kinetic study was performed using the Monod Model. The application of this model allowed observing a kinetic constant increase of the combined process (kFN = 0.036 h(-1)) when compared to the single anaerobic process (kF = 0.017 h(-1)).

“…Hybrid systems for OMW treatment were developed and tested recently. These systems usually consist of a physicochemical method combined with a biological one such as: ozonation/aerobic biological treatment, chemical oxidative procedure with FeCl 3 / aerobic biological treatment, coagulation–flocculation/anaerobic biological process, electrochemical oxidation combined with constructed wetlands, electro‐Fenton combined with anaerobic digestion or aerobic biological process and sequential treatment with adsorption, biological and photo‐Fenton oxidation . Each of these methods has been reviewed in several review papers and each has advantages and disadvantages.…”

BACKGROUND Many physicochemical, biological and disposal technologies have been suggested for the effective treatment of olive mill wastewaters (OMW), wastes with very high organic content, non‐readily degradable content and phytotoxic characteristics, and considered one of the major polluting agents in Mediterranean countries from agricultural activities. RESULTS The treatment of OMW by means of coagulation–flocculation using various inorganic materials (poly‐aluminum chloride – PAC, aluminum sulphate) and organic poly‐electrolytes (anionic polyacrylamide – Flocan 23–20, anionic polyelectrolyte – Praestol 2240) was investigated in this study. This technology was examined as a single stage treatment of two different (in composition) olive mill wastewaters, and a second treatment stage following aerobic biological treatment in a biofilter. Treatment effectiveness was assessed through dissolved chemical oxygen demand (COD), total phenolic content (TP), total solids (TS), total suspended solids (TSS) removal, and zeta potential. Results revealed that PAC presents better and more stable treatment efficiency than aluminum sulphate. The optimum electrolyte concentration varies for the wastewaters used depending on their composition and the electrolyte's chemical structure. An economic analysis was performed taking coagulant and flocculant costs into account.

The optimum electrolyte concentration varies for the wastewaters used depending on their composition and the electrolyte's chemical structure. An economic analysis was performed taking coagulant and flocculant costs into accountThe use of combinations of electrolytes and polyelectrolytes was effective at reducing all parameters analysed. Optimum treatment and economic performance was observed in the case of combined biological and physicochemical treatment, which achieved COD, TP, TS and TSS removal rates of 65.5%, 66%, 71% and 99.2%, respectively; this corresponds to 0.36 €/ m3 of treated OMW. © 2013 Society of Chemical Industry
