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 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 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 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 ... -
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 ... -
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
(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 ... -
Benchmarking real-time monitoring strategies for ethanol production from lignocellulosic biomass
(Elsevier, 2019-08)The goal of this paper is to review and critically assess different methods to monitor key process variables for ethanol production from lignocellulosic biomass. Because cellulose-based biofuels cannot yet compete with ... -
Biomass aggregation influences NaN3 short-term effects on anammox bacteria activity
(IWA Publishing, 2017-03)The main bottleneck to maintain the long term stability of the partial nitritation-anammox processes, especially those operated at low temperatures and nitrogen concentrations is the undesirable development of nitrite ... -
Biotransformation of organic micropollutants by anaerobic sludge enzymes
(Elsevier, 2019-04-01)Biotransformation of organic micropollutants (OMPs) in wastewater treatment plants ultimately depends on the enzymatic activities developed in each biological process. However, few research efforts have been made to clarify ... -
Blending based optimisation and pretreatment strategies to enhance anaerobic digestion of poultry manure
(Elsevier, 2018)Anaerobic digestion of poultry manure is limited by the excessive levels of nitrogen and the high concentration of dry matter. These limitations are usually overcome either by applying procedures to remove nitrogen or by ... -
Carbon footprint and nutritional quality of different human dietary choices
(Elsevier, 2018-12-10)Apart from industrial activities, our eating habits also have a significant environmental cost associated with crop cultivation, manufacturing processes, packaging, refrigeration, transport cooking and waste management. ... -
Cometabolic enzymatic transformation of organic micropollutants under methanogenic conditions
(American Chemical Society, 2017-02-15)Anaerobic digestion (AD) has been shown to have the biological potential to decrease concentrations of several organic micropollutants (OMPs) in sewage sludge. However, the mechanisms and factors behind these biotransformations, ... -
