Effect of limonene on anaerobic digestion of citrus waste and pretreatments for its improvement

RUIZ FUERTES, BEGOÑA (Universitat Politècnica de València, 2015-12-14)

[EN] Anaerobic digestion is a sustainable and technically sound way to valorise citrus waste if the inhibitory effect of the citrus essential oil (CEO) is controlled. Several strategies have been proposed to overcome these ...
Electrochemical treatment of a synthetic wastewater containing a sulphonated azo dye. Determination of naphthalenesulphonic compunds produced as main by-products

Del Río García, Ana Isabel; Fernández Sáez, Javier; Molina Puerto, Javier; Bonastre Cano, José Antonio; Cases Iborra, Francisco Javier (Elsevier, 2011-06-15)

The electrochemical treatment of wastewaters from textile industry is a promising technique for substances which are resistant to biodegradation. This paper deals with the electrochemical decolourisation/degradation of ...
Experimental study of the anaerobic urban wastewater treatment in a submerged hollow-fibre membrane bioreactor at pilot scale

Giménez García, Juan Bautista; Robles Martínez, Ángel; Carretero Martín, Laura; Durán Pinzón, Freddy; Ruano García, María Victoria; Gatti, Marcela Noemi; Ribes Bertomeu, Jose; Ferrer Polo, José; Seco Torrecillas, Aurora (Elsevier, 2011-10)

The aim of this study was to assess the effect of several operational variables on both biological and separation process performance in a submerged anaerobic membrane bioreactor pilot plant that treats urban wastewater. ...
Hybrid method for selection of the optimal process of leachate treatment in waste treatment and valorization plants or landfills

Martín Utrillas, Manuel Guzmán; Reyes Medina, Manuel; Curiel Esparza, Jorge; Cantó Perelló, Julián (Springer Verlag (Germany), 2015-04)

Leachate from waste landfill or treatment plants is a very complex and highly contaminated liquid effluent. In its composition, it is found dissolved organic matter, inorganic salts, heavy metals, and other xenobiotic ...
Influence of operating conditions on ceramic ultrafiltration membrane performance when treating textile effluents

Barredo Damas, Sergio; Alcaina Miranda, María Isabel; GEMMA, MATTEO; Iborra Clar, María Isabel; Mendoza Roca, José Antonio (IWA Publishing, 2011)

[EN] This work studies the performance of three commercial ceramic ultrafiltration membranes (ZrO 2-TiO 2) treating raw effluent from a textile industry. The effect of crossflow velocity at 3, 4 and 5 m s -1 as well as ...
Metabolic shift of polyphosphate-accumulating organisms with different levels of polyphosphate storage

Acevedo, B.; Oehmen, A.; Carvalho, G.; Seco, A.; Borras, L.; Barat Baviera, Ramón (Elsevier, 2012)

Previous studies have shown that polyphosphate-accumulating organisms (PAOs) are able to behave as glycogen-accumulating organisms (GAOs) under different conditions. In this study we investigated the behavior of a culture ...
Micropollutants removal in an anaerobic membrane bioreactor and in an aerobic conventional treatment plant

Agargues Llamas, Miguel Rafael; Robles Martínez, Ángel; Bouzas Blanco, Alberto; Seco Torrecillas, Aurora (IWA Publishing, 2012)

The paper expresses an attempt to tackle the problem due to the presence of micropollutants in wastewater which may be able to disrupt the endocrine system of some organisms. These kinds of compounds are ubiquitously present ...
Predictive analysis of urban waste generation for the city of Bogota , Colombia, through the implementation of decision trees-based machine learning, support vector machines and artifficial neural networks

Solano-Meza, Johanna; Orjuela Yepes, David; Rodrigo-Ilarri, Javier; Cassiraga, Eduardo Fabián (Elsevier, 2019)

[EN] This study presents an analysis of three models associated with artificial intelligence as tools to forecast the generation of urban solid waste in the city of Bogota, in order to learn about this type of waste's ...
Reverse osmosis concentration of press liquid from orange juice solid wastes:flux decline mechanisms

Garcia-Castello, Esperanza M.; Mayor López, Luis; Chorques, S.; Argüelles Foix, Angel Luís; Vidal Brotons, Daniel José; Gras Romero, María Luisa (Elsevier, 2011-10)

Orange juice production produces high amount of solid waste. An alternative for these wastes is their pressing with lime to obtain a press liquor stream and a dried solid for cattle feeding. The press liquor (around 10 ...
Specific detection of viable Listeria monocytogenes in Spanish wastewater treatment plants by Fluorescent In Situ Hybridization and PCR

Moreno Trigos, Mª Yolanda; Ballesteros, Lorena; García Hernández, Jorge; Santiago Cuéllar, Paula; González Pellicer, Ana; Ferrús Pérez, Mª Antonia (IWA Publishing, 2011-10)
