“…Consequently, the SE protocol has been applied for OMPs partition assessment into the organic matter compartments in order to estimate their bioavailability. Barret et al (2012) and Delgadillo (2011) confirmed that the bioavailable fraction is contained in the aqueous phase (free OMPs and sorbed to colloidal matter) and that the bioaccessibility depends on the pollutants sorbed to particles.…”

“…Applied on the batch reactor test, methane production curve and output fractions were well predicted as shown by figure 1 by calibrating the maximum growth rate of hydrolytic biomass. OMPs mass balance and model proposition Delgadillo-Mirquez (2011) has demonstrated that the OMPs biodegradation are mainly related with the upper biological pathway of anaerobic digestion (hydrolysis and acidogenesis). As a consequence, the bioavailability and bioaccessibility concept of organic matter could be useful for OMPs fate characterization.…”

“…Moreover, in the case of BMP2 where OMPs addition occurred, a bound-residue seemed to be created in the NE from the degradation of OMPs located in HLS. Delgadillo et al (2011) showed that combining bioavailability and cometabolism concepts on a dynamic simplified model allowed the prediction of the OMPs fate in anaerobic digestion. Consequently, OMPs degradation model is proposed (cf.…”

Population balance models (PBMs) represent a powerful modelling framework for the description of the dynamics of properties that are characterised by distributions. This distribution of properties under transient conditions has been demonstrated in many chemical engineering applications. Modelling efforts of several current and future unit processes in wastewater treatment plants could potentially benefit from this framework, especially when distributed dynamics have a significant impact on the overall unit process performance. In these cases, current models that rely on average properties cannot sufficiently capture the true behaviour and even lead to completely wrong conclusions. Examples of distributed properties are bubble size, floc size, crystal size or granule size. In these cases, PBMs can be used to develop new knowledge that can be embedded in our current models to improve their predictive capability. Hence, PBMs should be regarded as a complementary modelling framework to biokinetic models. This paper provides an overview of current applications, future potential and limitations of PBMs in the field of wastewater treatment modelling, thereby looking over the fence to other scientific disciplines.

“…The geohydrological settings and the continuously low redox potential in the peat soil ( Figure 6) create anaerobic conditions for microbial communities. Studies on the anaerobic digestion of organic micropollutants in sewage sludge show that, beside the community structure and substance availability, the residence time is another factor known to be crucial for the micropollutant degradation rate [83][84][85]. In most activated sludge systems, the residence time ranges from 10 to 65 days [61].…”

Abstract:In the present study, a mixture of treated wastewater and surface water was used to rewet a degraded fen peatland site during a three-year rewetting experiment. We studied the behavior and effects of micropollutants by means of hydrological, physico-chemical, microbiological and ecotoxicological monitoring. The highest concentrations of micropollutants in the treated wastewater were found for the pharmaceuticals carbamazepine and diclofenac, some metabolites, the sweetener acesulfame, tolyl-and benzotriazole and diatrizoate. In the underlying, shallow groundwater where treated wastewater application for rewetting had been expected to have the greatest impact due to seeping and evapotranspiration processes, only a sporadic occurrence of micropollutants was found. The influence of dilution by groundwater movements was examined by applying a geohydrological model. The sorption of micropollutants onto the peaty soil also played a role, as found for carbamazepine. Further processes such as photolysis, microbial decay under low redox conditions and plant uptake can be assumed to be relevant for the removal of many substances. Ecotoxicity tests with the soil before and after rewetting did not indicate any negative impact on the soil habitat quality by wastewater application, but clearly pointed at ecotoxicologically relevant geogenic arsenic concentrations at the study site. Although a positive effect on receiving surface water systems is expected if wastewater is applied on land instead of discharged to water bodies, the rewetted soil may turn into a sink for micropollutants in the long term. Hence, the findings of the present field study encourage further investigations in order to identify the governing processes in the elimination of micropollutants in rewetted peatlands flooded with treated wastewater.

“…Esse modelo prevê uma associação entre a velocidade de consumo do cometabólito com a velocidade de consumo da fonte de carbono ou energia. Assim, a velocidade de degradação do cometabólito é acelerada devido à produção de compostos redutores associada à degradação do substrato de crescimento (DELGADILLO-MIRQUEZ et al, 2011 …”

Obrigado pela amizade e agradável companhia por todos esses anos. A contaminação ambiental por antibióticos e antimicrobianos quimioterápicos despertou o interesse da comunidade científica devido à possibilidade do desenvolvimento de resistência bacteriana e de efeitos ecotóxicos sobre organismos não-alvo. As águas residuárias contaminadas representam a principal fonte de dispersão desses fármacos para o meio ambiente. Enquanto as tecnologias anaeróbias têm sido crescentemente aplicadas para o tratamento de águas residuárias de origem agroindustrial, frequentemente contaminadas com antimicrobianos, pouco se sabe sobre as transformações que esses micropoluentes podem sofrer durante o tratamento. O objetivo do presente trabalho foi a investigação da degradação do antimicrobiano veterinário sulfametazina (SMZ) durante o tratamento anaeróbio de água residuária de suinocultura. Para tanto, foram conduzidas três fases experimentais. Na primeira fase, ensaios em batelada foram realizados com o intuito de avaliar a contribuição da biodegradação anaeróbia e de outros fenômenos na remoção de SMZ da fase líquida. A segunda fase envolveu a operação de três reatores anaeróbios contínuos em escala de bancada alimentados com água residuária sintética contaminada com SMZ, um reator anaeróbio horizontal de leito fixo (RAHLF), um reator anaeróbio de mistura e biomassa imobilizada (RAMBI) e um reator anaeróbio de fluxo ascendente e manta de lodo (UASB). Avaliou-se o efeito da variação da DQ...
