TL;DR: In this paper, the authors evaluated the influence of inoculation of endophytic bacteria on the detoxification of sewage effluent in floating treatment wetlands (FTWs) and concluded that endophyte-assisted FTWs can be the most sustainable and affordable approach for in situ remediation of sewage.

TL;DR: In this paper, the fate and seasonal variation of several typical endocrine-disrupting chemicals (EDCs), including estrone (E1), 17 beta-estradiol (E2), 17 alpha-ethylenediol (EE2), estriol (E3), bisphenol A (BPA), and 4-nonylphenol (NP), were investigated in a municipal sewage treatment plant employing an anaerobic/anoxic/oxic (A/A/O) process located in Beijing, China by monitoring their concentrations in both

TL;DR: The results revealed the optimal pretreatment condition for the biodegradation of piggery wastewater with microalgae for subsequent production of high-efficient biodiesel.
Abstract: The feasibility of using a microalga Chlorella vulgaris YSW-04 was investigated for removal of nutrients from piggery wastewater effluent. The consequent lipid production by the microalga was also identified and quantitatively determined. The wastewater effluent was diluted to different concentrations ranging from 20 to 80 % of the original using either synthetic media or distilled water. The dilution effect on both lipid production and nutrient removal was evaluated, and growth rate of C. vulgaris was also monitored. Dilution of the wastewater effluent improved microalgal growth, lipid productivity, and nutrient removal. The growth rate of C. vulgaris was increased with decreased concentration of piggery wastewater in the culture media regardless of the diluent type. Lipid production was relatively higher when using synthetic media than using distilled water for dilution of wastewater. The composition of fatty acids accumulated in microalgal biomass was dependent upon both dilution ratio and diluent type. The microalga grown on a 20 % concentration of wastewater effluent diluted with distilled water was more promising for generating high-efficient biodiesel compared to the other culture conditions. The highest removal of inorganic nutrients was also achieved at the same dilution condition. Our results revealed the optimal pretreatment condition for the biodegradation of piggery wastewater with microalgae for subsequent production of high-efficient biodiesel.

TL;DR: A rapid multi-step procedure, potentially amenable to automation, was proposed for quantifying viable and active bacterial cells, estimating their biovolume using flow cytometry (FCM) and to calculate their biomass within the main stages of a wastewater treatment plant.
