“…The water produced during and after the operation is considered as high-strength wastewater, because of the presence of protein, fats, oil, and grease (FOG) with a high tendency for rapid acidification. The chemical oxygen demand (COD) and biological oxygen demand (BOD) are normally found to be tens of thousands mg/L [ 4 ]. This range varies from 18,000 mg/L to 43,000 mg/L [ 5 ], but the strength differs from one industry to another depending on the number of animals slaughtered.…”

In this study, the performance of a laboratory scale upflow anaerobic sludge blanket (UASB) reactor operating at mesophilic temperature (35 °C) was examined. Cattle slaughterhouse wastewater (CSWW) was used as the main substrate. The total and effective volumes of the reactor were 8 L and 6 L, respectively. Twelve different organic loading rates (OLR) were applied and the performance was evaluated. The chemical oxygen demand (COD) removal efficiency was more than 90% during batch study. In the continuous study, COD removal was also approximately 90% at OLR 0.4 g/L d−1 which subsequently dropped to below 50% when the loading rate increased to 15 g/L d−1. Approximately 5 L/d of biogas was obtained with high methane concentration at stages VI and XI corresponding to OLR of 2 and 10 g/L d−1, respectively. It was observed that the concentration of volatile fatty acids was low and that the alkalinity of the wastewater was sufficient to avoid acidification. Specific methane yields of 0.36 and 0.38 LCH4/g COD added were achieved at OLR 7 and 10 g/L d−1. A hydraulic retention time (HRT) of 1 day was sufficient to remove greater than 70% of COD which correspond to 89% methane concentration. Parameters like soluble COD, NH3-N, pH, alkalinity, total suspended solid (TSS), fats, oil, and grease were also investigated. The results show that the UASB reactor could serve as a good alternative for anaerobic treatment of CSWW and methane production.

“…A significant volume of highly polluted wastewater is generated by poultry slaughterhouses during the slaughtering stage and periodic washing of residual particles, which results in significant variations in the biodegradable organic matter concentration. Therefore, an efficient treatment process should be carried by poultry slaughterhouses to treat the wastewater before it is discharged into receiving water bodies and to subsequently prevent severe environmental pollution [4]. Several treatment methods have been reported for PSW over the past few decades.…”

“…The organic load contribution comes from different materials such as fat, oil and grease (FOG), lard, blood, undigested food, loose meat, paunch, colloidal particles suspended materials and soluble proteins [4]. As a result, poultry processing wastewater has high concentrations of biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS) form slaughtering, fats oils and grease (FOGs) and cleaning activities which filters into drinking reservoirs [5].…”

Poultry slaughterhouse wastewater (PSW) is usually disposed of by discharging it into watercourses, municipal wastewater treatment works (WWTWs), or by scattering it on grass and croplands. However, the hazardous nature of the PSW makes it injurious to human health and the environment. As a result, the South African Government has established a Waste Discharge Charge System (WDCS), which is based on the "polluter pays" principle, as a means to encourage industrial waste dischargers to reduce their waste and use water resources optimally. Therefore, the poultry industry is required to adopt the latest technologies that will reduce freshwater consumption and increase reuse practices to achieve zero effluent discharges. This paper will present wastewater treatment options available, and give motivation as to why Sumo, which is a wastewater process simulator, should be applied to evaluate the performance of an anaerobic bioreactor.

“…Different technologies have been employed for poultry slaughterhouse wastewater treatment, with electrochemical (EC) methods [ 10 ], aerobic and anaerobic systems [ 11 , 12 ], as well as submerged fibers [ 13 ], as examples. However, the variability of pollutants in the poultry slaughterhouse wastewater makes it difficult to achieve high-quality removal efficiency using a single treatment unit.…”

Industrial activities produce a variety of pollutants that may not be easily treated using centralized wastewater treatment systems based on a single treatment unit. The variability of the pollutants brings the importance of industrial-specific integrated wastewater treatment plants such as integrated membrane filtration systems. However, the performance of a membrane filtration process can be highly affected by the presence of high amounts of suspended particles in the raw wastewater. Therefore, proper selection of a pre-treatment unit prior to a membrane filtration wastewater treatment system is a key aspect of its performance. This study investigated the performance of an integrated membrane filtration treatment system connected to an electrochemical process (pre-treatment) on the purification of a poultry slaughterhouse wastewater toward achieving a high-quality effluent. The industrial-scale treatment plant installed at the Izhevsk Production Corporative (PC) poultry farm in Kazakhstan is composed of an electrochemical, ultrafiltration (UF), and reverse osmosis (RO) as the main treatment units. From the analysis results, the electrochemical pre-treatment unit was observed to be highly effective for the removal of some physicochemical parameters such as turbidity, color, total suspended solids, total iron, aluminum, chemical oxygen demand, and biochemical oxygen demand; with removal efficiency ranging from 71 to 85%. The low removal efficiency of the pre-treatment system was also observed from free and total chlorine, nitrites, nitrates, phosphates, and ammonium nitrogen; with removal efficiency ranging from 4 to 45%. While in general, the overall treatment train was observed to be highly efficient for some physicochemical parameters such as turbidity, color, total suspended solids, as well as chemical and biochemical oxygen demand; maintaining almost 100% removal efficiency throughout the study period. Also, the high removal efficiency of the electrochemical pre-treatment processes led to a relatively low rate of cake formation on the membrane filters.
