“…During phases III and IV, the SRT was 48 and 42 days at HRT's of 0.5 d and 0.33 d without recirculation and it decreased to 40 and 35 days at phases VII and VIII when recirculation was imposed at effluent to feed ratios of 1.5 and 2.0, respectively, showing a decline of 16.66%. Similar behaviour was reported by Buzzini and Pires (2007), when they employed partial recirculation for the treatment of wastewaters from pulp and paper plants.…”

“…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). Fig.…”

Due to the value of methane as a fuel, and perhaps also the importance of avoiding its release into the atmosphere (Weiland 2010), much research has been devoted to its generation during anaerobic treatment of P&P mill wastewater (Maat and Habets 1987;Korczak et al 1991;Minami et al 1991;Sierraalvarez et al 1991;Vidal et al 1997;Kortekaas et al 1998;Ahn and Forster 2002;Buzzini and Pires 2007;Yilmaz et al 2008;Tabatabaei et al 2010;Lin et al 2011;Saha et al 2011;Elliott and Mahmood 2012;Bayr et al 2013;Ekstrand et al 2013;Hagelqvist 2013;Hassan et al 2014;Meyer and Edwards 2014;Larsson et al 2015). …”

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 ...

“…One of the main problems of the anaerobic biological degradation of this type of wastewater is the high content of easily fermentable organic matter. Organic matter compounds cause a fast acidification of the wastewater that results in a high production of VFA and, therefore, it is necessary to monitor the content of VFA for the good performance of the anaerobic bioreactor [31,32]. The increase of VFA in the effluents implies that the acidogenic bacteria produce more VFA than what can be utilized by the acetogenic and methanogenic bacteria.…”

Evaluation of Hydraulic Retention Time on Treatment of Coffee Processing Wastewater (CPWW) in EGSB Bioreactor

Abstract:The coffee processing agro-industry generates large quantities of wastewater requiring systematic treatment prior to disposal. For this reason, the aim of this study was to evaluate the hydraulic retention times (HRT) in treatment of coffee processing wastewater (CPWW) using a laboratory scale Expanded Granular Sludge Bed (EGSB) bioreactor at different HRT (3 to 9 days). The EGSB was evaluated in mesophilic condition (26 ± 2 • C) with an average pH of 7.5 ± 0.2 to determine the chemical oxygen demand (COD) removal efficiency. According to the results, the COD removal efficiency increases from 94 to 98% when the HRT increase from 3 to 9 days; the α factor remained stable (0.98) throughout the evolution of the bioreactor. The HRT´s between 7-9 days generated effluents capable to be dischargeable into water bodies with a permitted COD concentration according to World Health Organization (WHO) and Official Mexican Environmental Regulations permissible limits. Results evidenced that the HRT of 9 days was the one that greater COD removal generated, so the EGSB bioreactor can be a sustainable alternative to solve the environmental problems, compared to other conventional methods to CPWW treatment.
