“…On the opposite, when OMW was pre-treated by photo-Fenton, the biological treatment with fungi did not promote substantial benefits on reducing COD, total phenolic content and toxicity. Nogueira et al [49] performed the olive wastewater treatment using biological treatment with fungi as a final step after the oxidation process. This sequential process achieved 38% and 31% of COD and TP removal, respectively.…”

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.

“…Nogueira et al [33] assessed the efficiency of combining photocatalytic oxidation, using two nanomaterials as catalysts (TiO 2 and Fe 2 O 3 ), with biological degradation by fungi (Pleurotus sajor caju and P. chrysosporium). Results showed that biological treatment with fungi after pretreatment with nanomaterials allowing COD, TP and ecotoxicity removal.…”

During the last few decades, olive oil industrial sector has grown as a result of the modernization of olive oil mills, in response to the increasing demand of olive oil worldwide. "s an undesired side efect, the amount of olive mill eluents OME) increased, especially as a result of changing old batch press method for the continuous centrifugation-based olive oil production processes currently used, which ensure higher productivity. This chapter presents the state of the art of OME management, with focus on biological and advanced oxidation processes, either alone or in combination, varying in complexity, ease of operation and costs associated. Up to this moment, there isn't a management strategy that can be adopted in a global scale, feasible in diferent socio-economic contexts and production scales. The most reasonable approach is to regard OME valorisation as a regional problem, deining decentralized treatment that in some cases can be implemented for a group of olive oil mills in the same geographic area. This aspect is receiving strong atention as European Commission is promoting the transition towards a circular economy, which aims at closing the production loop by recycling and reusing resources, bringing beneits for the environment, society and the economy.

“…Complete or incomplete dye mineralization via electromagnetic radiation (≥ 3.2 eV) is based on electron hole pair production followed by recombination due to a charge transference (oxidation or reduction) process (Claudinei et al, 2015;Fernandez et al, 2015;Fernandez et al, 2016). Thus, a desirable sequential textile effluent wastewater treatment would use ligninolytic fungi to reduce high organic material and color, suspended solid concentrations, and facilitate photocatalyst action, coupled to a photocatalysis course that abates colored byproducts and decreases wastewater toxicity (Nogueira et al, 2015;Punzi et al, 2015).…”

Textile industries produce effluent wastewater that, if discharged, exerts a negative impact on the environment. Thus, it is necessary to design and implement novel wastewater treatment solutions. A sequential treatment consisting of ligninolytic co-culture with the fungi Pleurotus ostreatus and Phanerochaete crhysosporium (secondary treatment) coupled to TiO 2 /UV photocatalysis (tertiary treatment) was evaluated in the laboratory in order to discolor, detoxify, and reuse textile effluent wastewater in subsequent textile dyeing cycles. After 48 h of secondary treatment, up to 80 % of the color in the wastewater was removed and its chemical and biochemical oxygen demands (COD, and BOD 5 ) were abated in 92 % and 76 %, respectively. Laccase and MnP activities were central to color removal and COD and BOD 5 abatement, exhibiting activity values of 410 U L −1 and 1 428 U L −1 , respectively. Subjecting wastewater samples to 12 h of tertiary treatment led to an 86 % color removal and 73 % and 86 % COD and BOD 5 abatement, respectively. The application of a sequential treatment for 18 h improved the effectiveness of the wastewater treatment, resulting in 89 % of color removal, along with 81 % and 89 % COD and BOD 5 abatement, respectively. With this sequential treatment a bacterial inactivation of 55 % was observed. TiO 2 films were reused continuously during two consecutive treatment cycles without thermic reactivation. Removal percentages greater than 50 % were attained. Acute toxicity tests performed with untreated wastewater led to a lethality level of 100 % at 50 % in Hydra attenuata and to a growth inhibition of 54 % at 50 % in Lactuca sativa. Whereas sequentially treated wastewater excreted a 13 % lethality at 6.25 % and an inhibition of 12 % at 75 % for H. attenuata and L. sativa, respectively. Finally, sequentially treated wastewater was reused on dyeing experiments in which 0.86 mg g −1 adsorbed dye per g of fabric, that is equivalent to 80 % of dye adsorption. AM.
