“…Furthermore, the low R-squared value may be due to the long simulation period and the large number of data considered. Due to the high complexity of the process and as stated by other researchers [8,28], a MAPE for the measured and predicted data of 7% to 15% is sufficient for the indication of the correct dynamic calibration. Figure 6 is a comparison between the measured biogas production from the King Island anaerobic digester and that of the predicted hypothetical digester created by the BioWin software.…”

“…This may contributed to reducing FOG materials from flowing to the pond and, as a result, reduced problems associated with the process, at least over the first eight months. In the author's previous article [8], a reduction to the inlet COD of around 70% was applied in order to match the experimental data with that simulated by BioWin. This reduction in inlet COD was applied to two abattoirs in Queensland, Churchill and Southern meat [8,11].…”

“…In the author's previous article [8], a reduction to the inlet COD of around 70% was applied in order to match the experimental data with that simulated by BioWin. This reduction in inlet COD was applied to two abattoirs in Queensland, Churchill and Southern meat [8,11]. This was a logical action due to the thick crust formed at the top of the ponds in these abattoirs, which measured around 1 m in some places of the ponds.…”

“…Due to the complexity of this process, it is difficult in practical situations to apply these variables and, consequently, to identify problems that may affect the performance. Currently, especially in Australia, there are difficulties associated with covered anaerobic lagoons [7,8]. Some anaerobic digesters in the meat industry have been investigated, and it has been found that there is currently a lack of knowledge of anaerobic process regarding the design, operation and upgrading of these to covered anaerobic digesters.…”

“…Modelling of the biogas production rate can also be used as an indication of the process performance [16]. In previous works by McCabe et al [8], BioWin 3.1 software was used to simulate chemical oxygen demand (COD) removal and the subsequent biogas generation rate from two abattoirs, where crust (high content of fat, oil and grease (FOG)) accumulation was an issue. In those previous works, it was shown by using simulation that a large percentage of influent COD around 70% is not taking part in the AD process.…”

Abstract:In this study, a simulation was carried out using BioWin 3.1 to test the capability of the software to predict the biogas potential for two different anaerobic systems. The two scenarios included: (1) a laboratory-scale batch reactor; and (2) an industrial-scale anaerobic continuous lagoon digester. The measured data related to the operating conditions, the reactor design parameters and the chemical properties of influent wastewater were entered into BioWin. A sensitivity analysis was carried out to identify the sensitivity of the most important default parameters in the software's models. BioWin was then calibrated by matching the predicted data with measured data and used to simulate other parameters that were unmeasured or deemed uncertain. In addition, statistical analyses were carried out using evaluation indices, such as the coefficient of determination (R-squared), the correlation coefficient (r) and its significance (p-value), the general standard deviation (SD) and the Willmott index of agreement, to evaluate the agreement between the software prediction and the measured data. The results have shown that after calibration, BioWin can be used reliably to simulate both small-scale batch reactors and industrial-scale digesters with a mean absolute percentage error (MAPE) of less than 10% and very good values of the indexes. Furthermore, by changing the default parameters in BioWin, which is a way of calibrating the models in the software, as well, this may provide information about the performance of the digester. Furthermore, the results of this study showed there may be an over estimation for biogas generated from industrial-scale digesters. More sophisticated analytical devices may be required for reliable measurements of biogas quality and quantity. OPEN ACCESSEnergies 2015, 8 455

In this study, removal of organic matter and nitrogen from a cattle slaughterhouse wastewater was investigated in a two‐stage anoxic–aerobic biological system, followed by UV‐C disinfection. Ecotoxicity of the raw, biotreated, and disinfected wastewater against the microalgae Scenedesmus sp. was evaluated in short‐term tests, while the potential of the microalgae as a nutrient removal step was addressed in long‐term experiments. Throughout 5 operational phases, the biological system was subjected to gradual reduction of the hydraulic retention time (8–1.5 day), increasing the organic (0.21–1.11 kgCOD·m−3·day−1) and nitrogen (0.05–0.28 kgN·m−3· day−1) loading rates. COD and total ammoniacal nitrogen (TAN) removal ranged within 83%–97% and 83%–99%, respectively. While providing alkalinity source, effluent TAN concentrations were below 5 mg·L‐1. Nitrate was the main nitrification product, while nitrite levels remained low (<1 mgN·L‐1). Upon supplementation of external COD as ethanol, total nitrogen removal reached up to 90% at the highest load (0.28 kgN·m−3·day−1). After UV‐C treatment, 3‐log reduction of total coliforms was attained. The 96‐hr ecotoxicity tests showed that all non‐diluted samples tested (raw, biologically treated and UV‐C irradiated wastewater) were toxic to microalgae. Nevertheless, these organisms were able to acclimate and grow under the imposed conditions, allowing to achieve nitrogen and phosphorous removal up to 99.1% and 43.0%, respectively. Practitioner points The treatment of a slaughterhouse wastewater in an anoxic–aerobic biological system followed by a UV‐C disinfection step was assessed. The pre‐denitrification system showed efficient simultaneous removal of organic matter and nitrogen from the wastewater under increasing applied loads. UV‐C disinfection worked effectively in reducing coliforms from the biotreated effluent, boosting the performance of microalgae on nutrients removal. Despite the toxicity to microalgae, they were capable to acclimate to the aqueous matrices tested, reducing efficiently the nutrients content. The combined stages of treatment presented great capacity for depleting up to 97% COD, 99% nitrogen, and 43% phosphorous.
