“…In general, pulp and paper mill effluents contain a complex mixture of various classes of organic compounds, such as degradation products of carbohydrates, lignin, and extractives (Uğurlu et al 2008;Uğurlu and Karaoğlu 2009). Polluting effluents are formed in wood preparation, pulping, pulp washing, screening, paper machine, and coating operations, and especially in bleaching operations (Ali and Shreekrishnan 2001;Pokhrel and Viraraghavan 2004;Savant et al 2006). Clearly, the properties of wastewater from various process stages depend on the type of process and raw material, the recirculation of the effluent, and the amount of water used (Pokhrel and Viraraghavan 2004).…”

“…Anaerobic bacteria able to degrade chlorinated organics are classified as alkyl dehalogenators and aryl dehalogenators (Mohn and Tiedje 1992). The alkyl dehalogenators include physiologically diverse groups of strict anaerobes and facultative anaerobes, such as methanogens, species of Clostridium, Acetobacterium woodii, and Shewanella (Savant et al 2006). These organisms mainly dechlorinate LMW compounds, such as chloroform, tetrachloroethene, dichloromethane, trichloroethane, and trichloroethene.…”

“…The effluents contain high values of biochemical oxygen demand (BOD), chemical oxygen demand (COD), and chlorinated chemicals that are collectively termed as absorbable organic halides (AOX). While AOX content is generally proportional to the chlorine consumption in bleaching (Savant et al 2006), this emission has been reduced by over 80% since 199080% since (Friere et al 2003. The ratio of BOD to COD is a particularly useful quantity because it represents the fraction of organic compounds in the effluent that are easy to degrade (McCubbin and Folke 1993).…”

“…5. Molecular structures of two chlorinated phenolsEven though chlorinated phenolics represent less than 2% of the organically bound chlorine in bleaching effluents, they are large contributors to effluent toxicity, carcinogenicity, and mutagenicity (Savant et al 2006;Kukkola et al 2011). The majority of organochlorinated compounds present in pulp and paper mill effluents are HMW chlorolignins (>1 kDa).…”

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 ...
