“…Moreover, the significantly positive correlations between COD consumption and P release under anaerobic condition with 0.9972 of R 2 , and between nitrate removal and P uptake in the anoxic mode (R 2 of 0.9874) also demonstrated that DPAO was dominant in the tanks included the BNR-IC system. These results are consistent with previous reports (Wang et al 2010;Guerrero et al 2012b;Lanham et al 2013) which suggested the existence of significantly positive correlations between anaerobic COD consumption and P release, anoxic nitrate removal and P uptake.…”

Abstract. Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of these treatments on TNT removal and changes in soil microbial community responsible for contaminant degradation. Chemical analyses revealed significant decreases in TNT concentrations, including reduction of some of the TNT to its amino derivates during the 28-day tests. The combination of bioaugmentation-biostimulation approach coupled with rye cultivation had the most profound effect on TNT degradation. Although plants enhanced the total microbial community abundance, blue fenugreek cultivation did not significantly affect the TNT degradation rate. The results from molecular analyses suggested the survival and elevation of the introduced bacterial strains throughout the experiment. Keywords: TNT, bioaugmentation, biostimulation, phytoremediation, microbial community.

“…It is suggested that water supply is centralized and water plants are built to ensure the quality of surface water in the pastoral areas by means of controlling of the source. Furthermore, post-treatment processes are needed to remove nitrogen from surface water by supplementing carbon resource [74][75][76] allowing Plateau pastoral area people get as less affected as possible from drinking water.…”

Water quality assessment in pastoral of Tibetan Plateau, which is water sources for about 40% of world's population and the runoff-yield area of Yellow rivers, is very important. In this paper, Xiahe county which belongs to Tibetan Plateau pastoral was investigated. Six parameters(via, chloride, COD, ammonia nitrogen, nitrate, fluoride, sulfate) were selected to assess the water quality and health degree by using fuzzy comprehensive evaluation methods. The hydrochemical type in surface water was of HCO3 --Mg 2+ -C a2+ type. The cations and anions in surface water were mainly from weathering and dissolution of carbonate rock. Results showed that the water quality in all 69 sampling sites was all of class Ⅰ. The integrated health degree reached more than 0.85 and the health rate were 100%. Although ammonia nitrogen was regarded as the main contamination factor, but it had a little effect on the entire body of water. Overall, the surface water qualities of most samples in Xiahe County was good condition.

“…Unfortunately, an external VFA addition is not usually cost-effective and it increases the overall plant carbon footprint. A promising and very attractive alternative would be focused on the utilization of waste materials that could be fermented to VFA (Guerrero et al, 2012). Glycerol is a good example of such wastes materials since it is a byproduct of biodiesel fuel production: about 1 L of glycerol is generated for every 10 L of produced biodiesel fuel produced.…”

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.
