Acidogenesis is a key step in the anaerobic biotransformation of organic micropollutants
(Elsevier, 2020)Understanding the role of the different anaerobic digestion stages on the removal of organic micropollutants (OMPs) is essential to mitigate their release from wastewater treatment plants. This study assessed the fate of ... -
Adsorption of an anionic dye (Congo red) from aqueous solutions by pine bark
(Nature Publishing Group, 2019)Pinus pinaster bark, an abundant by-product from the timber industry, has been studied as a potential low-cost adsorbent for the removal of Congo red (CR) dye from wastewaters. Surface morphological and physico-chemical ... -
Air-side ammonia stripping coupled to anaerobic digestion indirectly impacts anaerobic microbiome
(Wiley, 2019)Air‐side stripping without a prior solid–liquid phase separation step is a feasible and promising process to control ammonia concentration in thermophilic digesters. During the process, part of the anaerobic biomass is ... -
An environmental evaluation of food supply chain using life cycle assessment: A case study on gluten free biscuit products
(Elsevier, 2018-01)This paper assesses the environmental profile of the biscuit supply chain for producing high quality gluten-free biscuits. Three different types of biscuits were considered. The assessment followed a cradle-to-grave approach ... -
An innovative wastewater treatment technology based on UASB and IFAS for cost-efficient macro and micropollutant removal
(Elsevier, 2018)An innovative process based on the combination of a UASB reactor and an IFAS system is proposed in order to combine different redox conditions and biomass conformations to promote a high microbial diversity. The objective ... -
An optimised control system to steer the transition from anaerobic mono- to co-digestion in full-scale plants
(Royal Society of Chemistry, 2019-05-01)Traditional wastewater treatment plants (WWTPs) are electrical consumers, with a usual high demand in the range of 0.3 to 0.6 kWh/m3 of wastewater treated. Their digesters are commonly oversized, and consequently operated ... -
Analysis of biowaste-based materials in the construction sector: evaluation of thermal behaviour and life cycle assessment (LCA)
(Springer, 2022)The objective of the work is to evaluate the thermal behaviour and the environmental impact of selected building biowaste-based materials, mainly biomass from agrowaste. An evaluation of the state of the art of the materials ... -
Analysis of Spatial and Temporal Variability of the PAR/GHI Ratio and PAR Modeling Based on Two Satellite Estimates
(MDPI, 2020)The main objectives of this work are to address the analysis of the spatial and temporal variability of the ratio between photosynthetically active radiation (PAR) and global horizontal irradiance (GHI), as well as to ... -
Application of anammox-based processes in urban WWTPs: are we on the right track?
(MDPI, 2021)The application of partial nitritation and anammox processes (PN/A) to remove nitrogen can improve the energy efficiency of wastewater treatment plants (WWTPs) as well as diminish their operational costs. However, there ... -
Application of aqueous two phase systems based on polyethylene glycoland sodium citrate for the recovery of phenolic compounds from eucalyptus wood
(Universidad Bio-Bio, 2015)This paper proposes an alternative way to intensify the exploitation of Eucalyptus wood wastes before valorisation for energy production. An aqueous two-phase system (ATPS) based on PEG 2000 and sodium citrate was investigated ... -
Aqueous extracts characteristics obtained by ultrasound-assisted extraction from Ascophyllum nodosum seaweeds: effect of operation conditions
(Springer, 2021)Aqueous extracts from Ascophyllum nodosum brown edible seaweeds were obtained after continuous ultrasound-assisted extraction. The effect of sonication time (from 2 to 6 min), sonication amplitude (from 80 to 100%) and ... -
Arsenic Retention on Technosols Prepared with Nanoparticles and Ferric Soil from Mine Drainage Water
(Hindawi, 2018)Mining activities generate a large amount of solid waste and acid drains that contain heavy metals in high concentrations. In wastewater of gold mines from Southern Ecuador (Portovelo), arsenic concentrations between 4.8 ... -
Assessing the sustainability dimension at local scale: Case study of Spanish cities
(Elsevier, 2020)Nowadays, cities host most of the world population. As a result of human activities within their boundaries, most greenhouse gases emissions, natural resources consumption and waste generation are concentrated in urban ... -
Assessment of a fast method to predict the biochemical methane potential based on biodegradable COD obtained by fractionation respirometric tests
(Elsevier, 2020)The biochemical methane potential test (BMP) is the most common analytical technique to predict the performance of anaerobic digesters. However, this assay is time-consuming (from 20 to over than 100 days) and consequently ... -
Assessment of the fate of organic micropollutants in novel wastewater treatment plant configurations through an empirical mechanistic model
(Elsevier, 2020)Novel wastewater treatment plants (WWTPs) are expected to be less energetically demanding than conventional ones. However, scarce information is available about the fate of organic micropollutants (OMPs) in these novel ... -
Bacterial community dynamics in long‐term operation of a pilot plant using aerobic granular sludge to treat pig slurry
