“…The previous study showed that the sequencing batch reactor (SBR) was flexible and possessed good adaptability to influent wastewater characteristics, with more convenient operation 20 . It was reported that only 74.8% COD was removed when SBR was applied in paper‐making wastewater treatment 21 . The effluent COD of SBR system was around 252 mg L −1 , which was higher than the results in this study.…”

“…20 It was reported that only 74.8% COD was removed when SBR was applied in paper-making wastewater treatment. 21 The effluent COD of SBR system was around 252 mg L −1 , which was higher than the results in this study. However, COD and TN in the effluent of the IC-A/O process still could not meet the discharge standard of first grade (50 and 15 mg L −1 ).…”

BACKGROUND: The paper-making industry has developed rapidly in recent years. The paper-making process consumes much water and generates large amounts of wastewater. The reuse of the produced wastewater helps to save water consumption and reduce environmental pollution. Effective methods to treat and recycle paper-making wastewater are urgently sought. RESULTS: In this study, the performance of a full-scale internal circulation-anoxic/oxic (IC-A/O)-ultrafiltration (UF)-reverse osmosis (RO) membrane system for reclamation and reuse of paper-making wastewater was investigated. Results showed that the integrated system presented a stable and highly efficient performance. The effluent concentrations of chemical oxygen demand, total organic carbon, biochemical oxygen demand , NH 4 + nitrogen and total nitrogen were 12, 4, 0.3, 0.5 and 2.9 mg L −1. gas chromatographic-mass spectrometric results showed that the organic composition in each process of the IC-AO-UF-RO system varied significantly. Acute biological toxicity was obviously reduced, with an effluent toxic unit value of 3.11. The results of particle size distribution indicated that anaerobic granular sludge (around 3 mm) was formed in an IC reactor. Anaerolinea, Propioniciclava and Thauera were the main contributors to pollutant removal. Advanced treatment by the UF-RO system achieved complete removal of suspended solids, silt density index and turbidity with little hardness and conductivity in the final effluent, which allowed for reclamation of paper-making wastewater. CONCLUSION: Water reuse and energy recycling were successfully realized in the built-up IC-AO-membrane reactor system.

“…A subsequent photo-Fenton with 19 kJ/L of energy, 41 mM of H 2 O 2 consumed and [Fe 2+ ] = 10 mg/L) achieved 90% DOC mineralization and met the Portuguese legal requirements for discharge into natural waters. Abedinzadeh et al [97] also reported a combination of biological treatment (SBR) with AOPs applied to pulp and paper wastewater. In this study it was possible to achieve 92.1% COD reduction and 90.3% of color removal with dosages of Fe 2+ =3 mM and H 2 O 2 = 9 mM.…”

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.

“…The optimization of the process variables and the linear, interactive and quadratic effects on the process was studied through CCF. 23,24 In this study three independent variables A: pH, B: hydrogen peroxide (H 2 O 2 ) dose, C: ferrous sulphate (FeSO 4 ) dose and residual COD as response was evaluated by 20 experiments (2 n + 2n + x 0, 2 3 ¼ 8factorial points; 2 Â 3 ¼ 6axial points; 6centre points). The Table 1 shows the summary of design parameters for degradation of landll leachate by oxidative Fenton's process with respect to actual and coded factors for CCF design.…”
