“…The conventional Fenton process has been tested in the pulp and paper industry at laboratory scale to polish different mill effluents (from kraft pulp to recovered paper mills) reporting good oxidation removal efficiencies (COD removal > 60%; Hermosilla et al 2015), although the partially-oxidized composition of the treated wastewater did not show a reduction of toxicity to Artemia salina in comparison with the untreated effluent (Tambosi et al 2006). Figure 14 outlines the process sequence in a conventional Fenton system for wastewater treatment.…”

The pulp and paper (P&P) industry worldwide has achieved substantial progress in treating both process water and wastewater, thus limiting the discharge of pollutants to receiving waters. This review covers a variety of wastewater treatment methods, which provide P&P companies with costeffective ways to limit the release of biological or chemical oxygen demand, toxicity, solids, color, and other indicators of pollutant load. Conventional wastewater treatment systems, often comprising primary clarification followed by activated sludge processes, have been widely implemented in the P&P industry. Higher levels of pollutant removal can be achieved by supplementary treatments, which can include anaerobic biological stages, advanced oxidation processes, bioreactors, and membrane filtration technologies. Improvements in the performance of wastewater treatment operations often can be achieved by effective measurement technologies and by strategic addition of agents including coagulants, flocculants, filter aids, and optimized fungal or bacterial cultures. In addition, P&P mills can implement upstream process changes, including dissolved-air-flotation (DAF) systems, filtration save-alls, and kidney-like operations to purify process waters, thus reducing the load of pollutants and the volume of effluent being discharged to end-of-pipe wastewater treatment plants.

“…has been shown that it may be able to reduce over the 30% content of high molecular 16 weight compounds present in cellulose bleaching effluents (Yeber et al, 2000). 17 Therefore, TiO2-photocatalysis may be considered as an interesting pre-oxidation step 18 preceding biological treatment of paper industry wastewater. In fact, biodegradability 19 was improved along the TiO2-photocatalytic treatment of RO retentate, even achieving 20 close figures to those developed by ethylene glycol (≈100% COD removal) when 10 21 g·L -1 of TiO2 were used (Figure 7).…”

Optimization of conventional Fenton and ultraviolet-assisted oxidation processes for the treatment of reverse osmosis retentate from a paper mill

1According to current environmental legislation concerned with water scarcity, paper 2 industry is being forced to adopt a zero liquid effluent policy. In consequence, reverse 3 osmosis (RO) systems are being assessed as the final step of effluent treatment trains 4 aiming to recover final wastewater and reuse it as process water. One of the most 5 important drawbacks of these treatments is the production of a retentated stream, which 6 is usually highly loaded with biorecalcitrant organic matter and inorganics; and this 7 effluent must meet current legislation stringent constraints before being ultimately 8 disposed. The treatment of biorefractory RO retentate from a paper mill by several 9 promising advanced oxidation processes (AOPs) -conventional Fenton, photo-Fenton 10 and photocatalysis-was optimized considering the effect and interaction of reaction 11 parameters; particularly using response surface methodology (RSM) when appropriate 12 (Fenton processes). The economical cost of these treatments was also comparatively 13 assessed. Photo-Fenton process was able to totally remove the COD of the retentate, and 14 resulted even operatively cheaper at high COD removal levels than conventional 15 Fenton, which achieved an 80% reduction of the COD at best. In addition, although 16 these optimal results were produced at pH = 2.8, it was also tested that Fenton processes 17 are able to achieve good COD reduction efficiencies (> 60%) without adjusting the 18 initial pH value, provided the natural pH of this wastewater was close to neutral. 19Finally, although TiO2-photocatalysis showed the least efficient and most expensive 20 figures, it improved the biodegradability of the retentate, so its combination with a final 21 biological step almost achieved the total removal of the COD. 22Keywords: Advanced oxidation processes; Fenton; photo-Fenton; photocatalysis; 23 reverse osmosis retentate; paper mill effluents; response surface methodology. 24 AOPs treatment of RO retentate from a paper millDaphne Hermosilla et al.3

“…Tambosi et al 2006;Kazmi and Thul 2007) it has also been indicated that it was really better performed at a pH value ranging from 5.0 to 6.0 due to the final coagulation of iron hydroxides, which further favors COD and color removals (Catalkaya and Kargi 2007;Tambosi et al 2006). In fact, performing this treatment at more basic initial pH implies avoiding pH-control operation and cost, and the process itself tends to produce acids that lower the pH to more efficient acidic values anyway.…”

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.
