Biological Nutrient Removal Model Nº 2 (BNRM2): A general model for Wastewater Treatment Plants

Barat Baviera, Ramón; Serralta Sevilla, Joaquín; Ruano García, María Victoria; Jiménez Douglas, Emérita; Ribes Bertomeu, Jose; Seco Torrecillas, Aurora; FERRER, J. (IWA Publishing, 2013)

This paper presents the plant-wide model Biological Nutrient Removal Model No. 2 (BNRM2). Since nitrite was not considered in the BNRM1, and this previous model also failed to accurately simulate the anaerobic digestion ...
Caenorhabditis elegans to Model the Capacity of Ascorbic Acid to Reduce Acute Nitrite Toxicity under Different Feed Conditions: Multivariate Analytics on Behavioral Imaging

Verdu, Samuel; Pérez Jiménez, Alberto José; Carrascosa, Conrado; Barat Baviera, José Manuel; Talens Oliag, Pau; Grau Meló, Raúl (MDPI AG, 2021-02)

[EN] Nitrocompounds are present in the environment and human diet and form part of vegetables and processed meat products as additives. These compounds are related to negative impacts on human and animal health. The ...
Effect of pH and HNO2 concentration on the activity of ammonia-oxidizing bacteria in a partial nitritation reactor

Claros Bedoya, Javier Alfonso; Jiménez Douglas, Emérita; Aguado García, Daniel; FERRER, J.; Seco Torrecillas, Aurora; Serralta Sevilla, Joaquín (IWA Publishing, 2013)

Ammonia-oxidizing bacteria (AOB) are very sensitive to environmental conditions and wastewater treatment plant operational parameters. One of the most important factors affecting their activity is pH. Its effect is ...
Effect of pH and nitrite concentration on nitrite oxidation rate

Jiménez Douglas, Emérita; Giménez García, Juan Bautista; Ruano García, María Victoria; FERRER, J.; Serralta Sevilla, Joaquín (Elsevier, 2011-07-29)

The effect of pH and nitrite concentration on the activity of the nitrite oxidizing bacteria (NOB) in an activated sludge reactor has been determined by means of laboratory batch experiments based on respirometric techniques. ...
Effect of temperature on nitrite and water diffusion in pork meat

Gómez Salazar, Julián Andrés; Sanjuán Pellicer, María Nieves; Bon Corbín, José; Arnau, J.; Clemente Polo, Gabriela (Elsevier, 2015-03)

[EN] Nitrites are important food additives. The nitrite movement in meat is assumed to occur by means of a diffusion process. The objective of this study was to investigate the effect of temperature on nitrite and water ...
Estudio de la competencia entre microalgas y bacterias amonioxidantes en la eliminación de nutrientes del efluente de un reactor anaerobio de membranas (AnMBR)

Montero Marqués, Paula María (Universitat Politècnica de València, 2019-06-12)

[ES] Debido al aumento de la población y al impacto negativo que producen las actividades humanas sobre el medio ambiente, resulta necesario investigar y desarrollar técnicas y procesos que satisfagan las necesidades humanas ...
Modeling of sodium nitrite and water transport in pork meat

Gómez, J.; Sanjuán Pellicer, María Nieves; Arnau, J.; Bon Corbín, José; Clemente Polo, Gabriela (Elsevier, 2019-05)

[EN] Four models were used to simulate nitrite uptake and water loss during pork meat curing with sodium nitrite: three empirical ones (the Azuara, the Peleg and the Zugarramurdi and Lupin) and one theoretical (the ...
Monitoring pH and ORP in a SHARON reactor

Claros Bedoya, Javier Alfonso; Serralta Sevilla, Joaquín; Seco Torrecillas, Aurora; Ferrer Polo, José; Aguado García, Daniel (IWA Publishing, 2011)

This paper analyses the valuable information provided by the on-line measurements of pH and oxidation reduction potential (ORP) in a continuous single high ammonia removal over nitrite (SHARON) reactor. A laboratory-scale ...
Nanostructured catalysts for the continuous reduction of nitrates and bromates in water

Yuranova, T.; Kiwi-Minsker, L.; Franch Martí, Cristina; Palomares Gimeno, Antonio Eduardo; Armenise, S.; Garcia-Bordeje, E. (American Chemical Society, 2013-10-02)

[EN] Nanostructured C-based catalysts have been developed to be used in continuously operated (open-flow) reactors for the removal of bromates and nitrates from polluted water. The catalysts contain transition-metal (Pd, ...
Nitrite inhibition of microalgae induced by the competition between microalgae and nitrifying bacteria

Gonzalez-Camejo, Josue; Montero, P.; Aparicio, S.; Ruano, M. V.; Borras, L.; Seco, A.; Barat, Ramón (Elsevier, 2020-04-01)

[EN] Outdoor microalgae cultivation systems treating anaerobic membrane bioreactor (AnMBR) effluents usually present ammonium oxidising bacteria (AOB) competition with microalgae for ammonium uptake, which can cause nitrite ...
Uncertainty Modelling to Evaluate Nitrogen Balances As a Tool to Determine N2 and N2O Formation in Ammonia Bioscrubbers

Estellés Barber, Fernando; Calvet Sanz, Salvador; Melse, Roland W.; Ogink, Nico (Mary Ann Liebert, 2012)

Biological scrubbers aim at reducing gaseous ammonia emissions by transferring it to a water phase followed by conversion to nitrite and nitrate. A small part of the removed nitrogen may be emitted as N 2 and N 2O produced ...
