In this study, kinetics of biological carbon, nitrogen, and phosphorous removal from a synthetic wastewater in an integrated rotating biological contactoractivated sludge system was investigated. The experimental data obtained from varying four significant independent factors viz., hydraulic retention time, chemical oxygen demand for nitrogen to phosphorus ratio, internal recirculation from aerobic to anoxic zone and disks rotating speed were used for the process kinetic modeling. In order to obtain the bioprocess kinetic coefficients, Monod, firstorder and Stover-Kincannon models were employed. As a result, Monod and Stover-Kincannon models were found to be the appropriate models to describe the bioprocess in the rotating biological contactor-activated sludge system as the determination coefficient for the first-order model obtained less than 0.79. According to the Monod model, growth yield, microbial decay rate, maximum specific biomass growth rate, and half-velocity constant coefficients were found to be 0.712 g VSS/g COD, 0.008/d, 5.54/d and 55 mg COD/L, respectively. From Stover-Kincannon model, the maximum total substrate removal rate constant and half-velocity constant were determined as 15. 2, 10.98, 12.05 g/L d and 14.78, 7.11, 6.97 mg/L for chemical oxygen demand, nitrogen and phosphorus removal, respectively. The kinetic parameters determined in this study can be used to improve the design and operation of the biological contactor-activated sludge system in full scale.

“…For that reason, many authors have investigated about these parameters (Garcia-Pena et al 2011;Wu et al 2010). Furthermore, the most functional parameters for evaluating the efficiency of biogas production are the reduction in VS or COD (Debik and Coskun 2009;Demir et al 2011;Demirer and Chen 2005;Razaviarani et al 2013;Yangin-Gomec and Ozturk 2013;Ye et al 2013). Figure 1 shows important parameters of operating or performance compared to biogas-methane production from different substrates.…”

This literature review surveys the previous and current researches on the co-digestion of anaerobic processes and examines the synergies effect of co-digestion with cattle manure. Furthermore, this review also pays attention to different operational conditions like operating temperature, organic loading rate (OLR), hydraulic retention time (HRT), chemical oxygen demand (COD) and volatile solid (VS) removal efficiency and biogas or methane production. This review shows that anaerobic mono-digestion of cattle manure usually causing poor performance and stability. Anaerobic studies were generally performed under mesophilic conditions maintained between 35 and 37°C. Organic waste loading rate generally ranges from 1 to 6 g VS-COD L -1 day -1 stable condition in anaerobic digester. Generally, studies show that HRT for co-digestion of fruit-vegetables waste and industrial organic waste appears to exceed 20 days. However, the anaerobic co-digestion process is generally operated at HRT of between 10 and 20 days. VS and COD removal efficiency usually reaches up to 90 % due to codigestion with different type organic waste. Methane-biogas production is generally obtained between 0.1 and 0.65 L CH 4 -biogas g -1 VS.

“…BEUX et al (2007) Although it has been observed high values of AB and reduced values of AVT, the relationship between the intermediate and partial alkalinity (AI/AP) was superior to 0.3 which may indicate a disturbance in the process of anaerobic digestion (RIPLEY et al, 1986). DEBIK & COSKUN (2009) observed in anaerobic reactors used in effluents treatment of slaughterhouse, alkalinity values near to 1,500 mg L -1 and AI/AP ratio inferior than 0.3 to an average of COV of 2.73 kg m -3 d -1 . However, the affluent alkalinity to the reactor was 1.315 mg L -1 , almost three times that observed in this study.…”

“…Anaerobic systems have been tested with success in removing organic matter of slaughterhouse effluent (DEBIK & COSKUN, 2009;MÉNDEZ-ROMERO et al, 2011;RAJAKUMAR et al, 2012;PARK et al, 2012), reaching DQO removal efficiencies greater than 90% with the application of volumetric organic loads of up to 12 kg m -3 d -1 . However, the limitations of the anaerobic process in UASB reactors are related to the hydrolysis of organic suspended solids of the affluent, considered detrimental to development of granular sludge.…”

This study aimed to evaluate the start-up of a horizontal anaerobic fixed bed reactor (HAFBR) followed by an upflow anaerobic sludge blanket (UASB) for the slaughterhouse wastewater treatment. HAFBR was filled with bamboo rings and had 1.2 m in length, 0.10 m in diameter and volume of 7.5 L. The UASB had the volume of 15 L. The HAFBR and UASB operated at organic loading rate and hydraulic retention time average of 8.46 and 3.77 kg m -3 d -1 of COD and 0.53 and 0.98 days, respectively. During 150 days of monitoring system it was found pH 6.8, relatively high values of bicarbonate alkalinity (> 1000 mg L -1 ) and reduced values of volatile acids (70 to 150 mg L -1 ), which afforded average removal efficiencies of COD total and total suspended solids of the order of 31 and 23% in HAFBR and 79% and 63% in UASB. It can be concluded that the generation and consumption of bicarbonate alkalinity and total volatile acids, thereby maintaining the pH during the study indicated stable operation of the reactors. The COD removal in the reactors was satisfactory especially when it considers that the assessment was conducted in a period of adaptation of organisms to the effluent and also the high organic load applied during this period.KEYWORDS: UASB, anaerobic filter, slaughterhouse, organic matter. , o que proporcionou eficiências médias de remoção de DQO total e sólidos suspensos da ordem de 31 e 23% no RAHLF e de 79 e 63% no UASB. Pode-se concluir que a geração de alcalinidade bicarbonato e consumo de ácidos voláteis totais e consequente manutenção do pH durante o estudo indicaram operação estável dos reatores. A remoção de DQO nos reatores foi satisfatória, principalmente quando se considera que a avaliação foi realizada em per íodo de adaptação dos microrganismos ao efluente e também à elevada carga orgânica aplicada durante este período.
