Simultaneous degradation of ciprofloxacin, amoxicillin, sulfathiazole and sulfamethazine, and disinfection of hospital effluent after biological treatment via photo-Fenton process under ultraviolet germicidal irradiation
(2018-05-01)
A UVC-assisted photo-Fenton process was applied to hospital wastewater that had been submitted to anaerobic treatment. Low iron (10 μM; 0.56 mg L−1) and H2O2 (500 μM; 17 mg L−1) concentrations were used at the natural pH ...
Microbial processes and bacterial populations associated to anaerobic treatment of sulfate-rich wastewater
(ELSEVIER SCI LTD, 2010)
A pilot-scale (1.2 m(3)) anaerobic sequencing batch biofilm reactor (ASBBR) containing mineral coal for biomass attachment was fed with sulfate-rich wastewater at increasing sulfate concentrations. Ethanol was used as the ...
Post-treatment of effluents from the sulfate reduction process by anaerobic sequencing batch biofilm reactors
(ELSEVIER SCIENCE BV, 2009)
The main objective of this research was to evaluate the potential use of a bench-scale anaerobic sequencing batch biofilm reactor (ASBBR) containing mineral coal as inert support for removal Of Sulfide and organic matter ...
Living in the oxygen minimum zone: A metabolic perspective

Anaerobic effluent disinfected with ozone/hydrogen peroxide efluente anaeróbio desinfetado com ozônio/peróxido de hidrogênio
(2012-01-01)
This research aimed at studying the oxidation process, to verify the effectiveness of coliform inactivation and to evaluate the formation of ozonation disinfection byproducts (DBP) in anoxic sanitary wastewater treated ...
Effect of Substrate Concentration on Dark Fermentation Hydrogen Production Using an Anaerobic Fluidized Bed Reactor
(HUMANA PRESS INCTOTOWA, 2012)
The effect of substrate (glucose) concentration on the stability and yield of a continuous fermentative process that produces hydrogen was studied. Four anaerobic fluidized bed reactors (AFBRs) were operated with a hydraulic ...
LIMONENE QUANTIFICATION BY GAS CHROMATOGRAPHY WITH MASS SPECTROMETRY (GC-MS) AND ITS EFFECTS ON HYDROGEN AND VOLATILE FATTY ACIDS PRODUCTION IN ANAEROBIC REACTORS
(Soc Brasileira Quimica, 2020-07-01)
The inhibition effect of limonene on the organisms involved in anaerobic reactors may affect obtaining H-2 in this process. Rapid and precise limonene quantification is desirable to characterize wastewaters. The objective ...
Effect of sulphate concentration and sulphide desorption on the combined removal of organic matter and sulphate from wastewaters using expanded granular sludge bed (EGSB) reactors
(Pontificia Universidad Católica de Valparaíso, 2006)
Real evidence about zeolite as microorganisms immobilizer in anaerobic fluidized bed reactors
(Elsevier, 2007)
Using the scanning electronic microscopy, it was observed that natural zeolite possesses excellent physical characteristics as a support medium
in anaerobic fluidized bed reactors (AFBR). Samples for biomass analysis were ...
Anaerobic sequencing batch biofilm reactor applied to automobile industry wastewater treatment: Volumetric loading rate and feed strategy effects
(ELSEVIER SCIENCE SA, 2008)
This paper presents a technological viability study of wastewater treatment in an automobile industry by an anaerobic sequencing batch biofilm reactor containing immobilized biomass (AnSBBR) with a draft tube. The reactor ...
