“…"Pulp & paper effluent," BioResources 11(3), 7953-8091. 7958 operations sometimes may require more electrical energy in comparison to conventional treatment systems (Castillo and Vivas 1996;Buzzini and Pires 2002;El-Ashtoukhy et al 2009). According to Kamali and Khodaparast (2015), a goal of saving electrical energy costs may be responsible for a more widespread use of mesophilic (medium temperature) rather than thermophilic (higher temperature) conditions in biological treatment plants, even though the latter have been reported to achieve higher performance in many cases.…”

“…For instance, Bhunia and Ghangrekar (2008) found that such a system could be optimized by controlling the organic loading rate (OLR) to the system and by inoculating the system with thick sludge. Buzzini and Pires (2002) reported stable operation of an anaerobic reactor, with low maintenance and operational costs. Later work by the same group showed advantages of recirculating some of the sludge from treatment of P&P mill wastewater (Buzzini and Pires 2007).…”

“…In such systems the wastewater to be treated is introduced below a layer of sludge and allowed to percolate up through that layer (Maat and Habets 1987;Hynninen 1998). The flow velocity can be as high as 2 to 3 m/h in some high velocity upflow systems (Rajeshwari et al 2000).Under anaerobic conditions, where the production of sludge is expected to be less (Ashrafi et al 2015;Kamali and Khodaparast 2015), the same approach nevertheless has been evaluated (Lettinga et al 1980;Habets and Knelissen 1985;Maat and Habets 1987;Rajeshwari et al 2000;Buzzini and Pires 2002;Roest et al 2005;Bhunia and Ghangrekar 2008;Buyukkamaci and Koken 2010;Sheldon et al 2012).

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.

On the positive side, the industry is based on the usage of renewable, photosynthetic resources. On the other hand, the industry discharges huge quantities of aqueous effluents. Large volumes (up to 70 m 3 ) of wastewater ...

“…According to previous studies (Giger et al, 1984), the most persistent metabolite of NPEOs, endocrine disruptor NP, is formed under anaerobic conditions. As the anaerobic process is recognized as an effective technology for the pretreatment of high-strength industrial wastewater, for example, the pulp and paper mills wastewater, in which amounts of NPEO surfactant is commonly found (Buzzini and Pires, 2002;Hawrelak et al, 1999), it is therefore of great importance to understand the biotransformation behavior of NPEOs under anaerobic conditions.…”

Biotransformation of nonylphenol ethoxylates (NPEOs) during continuous anaerobic sewage treatment was compared with the aerobic treatment of sewage spiked with 23 µmol/L technical NPEOs over a period of 90 d. Immediate degradation of NPEOs was observed under both anaerobic and aerobic conditions, indicating that the enzymes and bacteria required for NPEO degradation existed abundantly in both aerobic and anaerobic sludge. Both treatments achieved high removal (> 92%) of the spiked NPEO9 mixture. Liquid chromatography-mass spectrometry (LC-MS) analysis showed that short-chain NPEOs (NPEO1-NPEO3) accumulated in anaerobic (2.01-2.56 µmol/L) and aerobic (1.62-2.03 µmol/L) effluents, with nonylphenol (NP) (0.24-0.31 µmol/L) as another group of metabolites in the anaerobic effluent, and nonylphenoxy carboxylates (NPECs) (2.79-3.30 µmol/L) in the aerobic effluent. Significant accumulation of NP in the anaerobic sludge and NPEO1-3 in the sludge of two reactors was observed. These results indicated that it was difficult to control these harmful metabolites in the conventional treatment processes. Denaturing gradient gel electrophoresis profiles of sludge samples support the speculation that the NPEO degradation bacteria might be the dominant indigenous species.

“…Buzzini & Pires (2002) [100] reached 80% on average removal of COD when treating diluted black liquor from a kraft pulp (KP) mill by using an UASB reactor. The performance of a bench scale UASB was also investigated by Buzzini, Gianotti, & Pires (2005) [101] for the treatment of simulated bleached and unbleached cellulose pulp mill wastewaters.…”
