“…Correspondingly, Medeiros et al (2008) also showed higher color and HMW fraction removals and biodegradability increase at pH = 7 than at 12. More recently, Merayo et al (2013) have reported non-significant differences between the ozone treatment of recycled paper mill effluents performed at pH = 7 and 12; and an even higher ozonation efficiency at pH = 7 for kraft pulp mill effluents. Considering all together, working at the typical pH values of neutral-basic pulp and paper mill effluents (pH = 7-9) addressed the great advantage of avoiding pH control mechanisms (Kreetachat et al 2007;Oeller et al 1997;Salokannel et al 2007).…”

“…Nevertheless, and as it has already been pointed out, ozone consumption rate will decrease during ozonation due to the progressive reaction with organic matter, so this decrease depends on the nature of the compounds present in the solution; that is, proportional to the amount of easily oxidized compounds (Fontanier et al 2005b;Salokannel et al 2007;Merayo et al 2013). Finally, Bierbaum and Oeller (2009) implemented on-line control systems for the continuous ozonation treatment of biologically treated effluents from recycled paper mills, showing that a controlled ozone production is useful and necessary, ensuring the stable operation of subsequent stages.…”

Nevertheless, slight pH variations may occur during the oxidation reaction due to the formation of small acid by-products (Balcioglu et al 2007;Merayo et al 2013) or the generation of carbonate along the mineralization process (Oeller et al 1997). …”

“…The pH is not usually as strongly basic as for a kraft process, and more starch-related products (rather than lignin ones) can be found (Amat et al 2005a), resulting that these effluents are more biodegradable (Merayo et al 2013;Thompson et al 2001). In addition, it is also important to consider that the papermaking operation with recycled fibers may introduce different chemical compounds in the effluent, such as EDTA, which is very difficult to degrade by biological technologies (Sundholm 1999).…”

“…Whereas the combination of biological treatments (anaerobic and aerobic) achieved about an 80% removal of different phtalates, photoFenton treatment achieved a 100% removal. In general, AOPs can be applied to industrial wastewater as a polishing step integrated with conventional chemical and/or biological processes in order to increase the overall treatment effectiveness (Alvares et al 2001;Balcioglu et al 2003;Legrini et al 1993;Merayo et al 2013;Oeller et al 1997;Tanaka and Ichikawa 1993).…”

Paper industry is adopting zero liquid effluent technologies to reduce fresh water use and meet environmental regulations, which implies water circuits closure and the progressive accumulation of pollutants that must be removed before water re-use and final wastewater discharge. The traditional water treatment technologies that are used in paper mills (such as dissolve air flotation or biological treatment) are not able to remove recalcitrant contaminants. Therefore, advanced water treatment technologies, such as advanced oxidation processes (AOPs), are being included in industrial wastewater treatment chains aiming to either improve water biodegradability or its final quality. A deep review of the current state of the art regarding the use of AOPs for the treatment of the organic load of effluents from the paper industry is herein addressed considering mature and emerging treatments for a sustainable water use in this sector. Wastewater composition, which is highly dependent of the raw materials being used in the mills, the selected AOP itself, and its combination with other technologies, will determine the viability of the treatment. In general, all AOPs have been reported to achieve good organics removal efficiencies (COD removal >40%; and about an extra 20% if AOPs are combined with biological stages). Particularly, ozonation has been the most extensively reported and successfully implemented AOP at an industrial scale for effluent treatment or reuse within pulp and paper mills; although Fenton processes (photo-Fenton particularly) have actually addressed better oxidative results (COD removal ≈65-75%) at lab scale, but still need further development at large scale.

Nowadays, an ever-increasing variety of organic contaminants in water has caused hazards to the ecological environment and human health. Many of them are persistent and non-biodegradable. Various techniques have been studied for sewage treatment, including biological, physical and chemical methods. Photocatalytic advanced oxidation processes (AOPs) have received increasing attention due to their fast reaction rates and strong oxidation capability, low cost compared with the non-photolytic AOPs. This review is dedicated to summarizing up-to-date research progress in photocatalytic AOPs, such as Fenton or Fenton-like reaction, ozonation and sulfate radical-based advanced oxidation processes. Mechanisms and activation processes are discussed. Then, the paper summarizes photocatalytic materials and modification strategies, including defect chemistry, morphology control, heterostructure design, noble metal deposition. The future perspectives and challenges are also discussed.

Influence of Alkalinity on the Efficiency and Catalyst Behavior of Photo‐Assisted Processes

The influence of carbonates on TiO 2 photocatalysis and the photo-Fenton process using Fe 0 as catalyst is unraveled. The aggregation behavior of each catalyst was monitored under different reaction conditions in order to assess the effect of carbonates on their performance. Carbonates drastically reduced the efficiency of photocatalysis because of aggregation of the TiO 2 catalyst, which led to the reduction of adsorbed pollutants. The addition of carbonates to the photo-Fenton process did not produce this strong catalyst aggregation. Therefore, oxidation-reduction reactions on the catalyst surface were not much reduced, and the efficiency of this process was not as strongly affected as that of TiO 2 photocatalysis.
