“…BioWin4 predictions correlated well with observed removals of PPCPs during aerobic biological secondary treatment (Blair et al 2013). On that basis, the semi-quantitative output of BioWin4 (v4.10) was used to estimate TOrC biodegradability here.…”

“…The removal efficiencies for the 24 h composites were calculated by mass balancing daily loads of influent and effluent, and then by using the captured fractions of the sampled influent by effluent sampling accounting for time-shift and hydraulic mixing. Most of the removal of the target compounds was observed during biological treatment which is generally the case for organic contaminants in wastewater (Blair et al, 2013;Joss et al, 2006;Khan and Ongerth, 2002). In some cases however, comparable levels of removal were also noted during primary and secondary clarification.…”

“…In the latter case, the level of the investigated compound is higher in the effluent than that in the influent to one of the treatment units or over the entire WWTP (Blair et al, 2013). Reasons for this can include the release of fecal particles during wastewater treatment, significant desorption from the return activated sludge thereby increasing their concentration throughout the treatment process (Göbel et al, 2007;Salgado et al, 2012) or the transformation of conjugate compounds to the parent compound during biological treatment (Monteiro and Boxall, 2010;Salgado et al, 2012).…”

• 19 drugs of abuse were studied throughout a wastewater treatment plant.• Drug levels were generally comparable between composite, POCIS and grab samples.• Overall drug removals during wastewater treatment varied between −84 and 90%.• Time-shifted mass balancing eliminated negative removals obtained with other approaches. In this study the levels of 19 drugs of abuse were estimated throughout a wastewater treatment plant using polar organic chemical integrative samplers (POCIS), 24 h composite samples and grab samples. Overall removal efficiencies and removals in between each treatment unit were calculated using load data for each sampling technique as well as removals that take into account the hydraulic residence time distribution of the treatment plant (time-shifted mass balancing approach). Amphetamine-type stimulants, cocaine and its major metabolite, benzoylecgonine and opioid levels determined with 24 h composite samples were generally comparable to those obtained with POCIS and grab samples. Negative mass balances resulting from the estimation of overall removal efficiencies by POCIS, day-to-day mass balancing of 24 h composite and grab sample data did not occur when the hydraulic retention time (HRT) distributions of the plant were taken into account for calculation. Among the compounds investigated, cocaine exhibited the highest overall removal (90%) while codeine had the lowest with 13%, respectively. Sampling between the treatment units revealed that highest removal occurs during biological treatment as compared to primary or secondary clarification. Methylenedioxyamphetamine (MDA), fentanyl, dihydrocodeine and heroin were not detected in wastewater at any of the sampling locations at the treatment plant regardless of the sampling technique. The study demonstrates the benefits of applying the time-shifted mass balancing approach to the calculation of removals of drugs of abuse during wastewater treatment. a b s t r a c t a r t i c l e i n f o

“…BioWin software (EnviroSim Associates Ltd., Hamilton, ON, Canada) is easy to use, although it requires the user to have extensive knowledge and experience with wastewater treatment processes [26,27]. BioWin is a Windows-based computer simulation model developed by EnviroSim Associated Ltd. BioWin is capable of simulating the behaviour of AD systems by integrating biological and chemical processes to effectively determine biogas yield.…”

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
