Effect of Coagulant-Flocculant Reagents on Aerobic Granular Biomass
(John Wiley & Sons, 2012)BACKGROUND: Technologies based on aerobic granular biomass are presented as a new alternative for its application to the wastewater treatment due to its advantages in comparison with the conventional activated sludge ones. ... -
Stability of aerobic granular biomass treating the effluent from a seafood industry
(University of Tehran, 2013)The aerobic granular systems represent a good alternative to substitute the conventional activated sludge process in the treatment of industrial effluents due to the lower surface requirements. In this work the effluent ... -
Enhanced ammonia removal at room temperature by pH controlled partial nitrification and subsequent anaerobic ammonium oxidation
(Taylor & Francis, 2014)The Anammox based processes are suitable for the treatment of wastewaters characterized by a low carbon to nitrogen (C/N) ratio. The application of the Anammox process requires the availability of an effluent with a ... -
A novel control strategy for single-stage autotrophic nitrogen removal in SBR
(Elsevier, 2014-08-27)A novel feedforward–feedback control strategy was developed for complete autotrophic nitrogen removal in a sequencing batch reactor. The aim of the control system was to carry out the regulation of the process while keeping ... -
Assessment of prebiotic potential of Akpan-yoghurt-like product and effects on the human intestinal microbiota
(Elsevier, 2015)The effect of Akpan (yoghurt-like product) consumption on the human intestinal microbiota was examined. The prebiotic potential of Akpan was assessed by in vitro fermentation using, as inocula, individual probiotic strains ... -
Filamentous bacteria existence in aerobic granular reactors
(Springer Verlag, 2015)Filamentous bacteria are associated to biomass settling problems in wastewater treatment plants. In systems based on aerobic granular biomass they have been proposed to contribute to the initial biomass aggregation process. ... -
Operation of an innovative WWTP with environmental objectives. A model-based analysis
(Elsevier, 2016)Operation of wastewater treatment plants can be subjected to economic, energetic and/or environmental objectives, besides the compliance with effluent limits. As trade-offs between different objectives are frequently ... -
Greenhouse Gases Emissions from Wastewater Treatment Plants: Minimization, Treatment, and Prevention
(Hindawi, 2016)The operation of wastewater treatment plants results in direct emissions, from the biological processes, of greenhouse gases (GHG) such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), as well as indirect ... -
Monitoring and diagnosis of energy consumption in wastewater treatment plants. A state of the art and proposals for improvement
(Elsevier, 2016)In response to strong growth in energy intensive wastewater treatment, public agencies and industry began to explore and implement measures to ensure achievement of the targets indicated in the 2020 Climate and Energy ... -
Optimal experimental design in the evaluation of food packaging compliance with safety regulations
(Elsevier, 2016)The determination of diffusivity of compounds that can be transferred from packaging into food products is a keystone to ensure consumer’s safety. However, no clear guidelines exist as how the diffusion experiment should ... -
Effect of oxygen on the microbial activities of thermophilic anaerobic biomass
(Elsevier, 2016)Low oxygen levels (ug O2 L-1) in anaerobic reactors are quite common and no relevant consequences are expected. On the contrary, higher concentrations could affect the process. This work aimed to study the influence of ... -
Is anaerobic digestion effective for the removal of organic micropollutants and biological activities from sewage sludge?
(Elsevier, 2016-06-14)The occurrence of emerging organic micropollutants (OMPs) in sewage sludge has been widely reported; nevertheless, their fate during sludge treatment remains unclear. The objective of this work was to study the fate of ... -
An exploratory data analysis of energy consumption of WWTP. Influencing factors and possible methods for benchmarking
(2016-06-27)Wastewater treatment plants are relevant energy consumers. As they carry out complex operations submitted to large variability caused by, among others, the influent and loading variations, the assessment of the performance ... -
Energy efficiency of wastewater treatment plants. Overview of the literature and critical discussion of energy data
(2016-06-29)In response to strong growth in energy intensive wastewater treatment, public agencies and industry began to explore and implement measures to ensure achievement of the target indicated in the 2020 Climate and Energy ... -
Bacterial community dynamics in long‐term operation of a pilot plant using aerobic granular sludge to treat pig slurry
(Wiley, 2016-07-08)Aerobic granular sludge represents an interesting approach for simultaneous organic matter and nitrogen removal in wastewater treatment plants. However, the information about microbial communities in aerobic granular ... -
ENERWATER project to standardize the energy audit and efficiency in municipal wastewater treatment plants
(2016-07-14)This project will develop, validate and disseminate a standardized methodology for continuously assessing, labelling and improving the overall energy performance of Waste Water Treatment Plants. The methodology will be ... -
Short and long term orange dye effects over AOB and anammox activities
(2016-09-07)In this research work the effects of orange azo dye over ammonia oxidizing bacteria (AOB) and anammox bacteria activities were tested. Adsorption onto the biomass was detected with both types of biomass however no biological ... -
A critical comparison of methods for benchmarking energy performance in WWTPs
(2016-10-11)The energy efficiency of wastewater treatment plants (WWTPs) is a subject of growing interests by water utility and WWTPs operators. As consequence, benchmarking in recent years has become an important tool to assess the ... -
