Removal and environmental risk assessment of contaminants of emerging concern from irrigation waters in a semi-closed microalgae photobioreactor
(Elsevier, 2021-03)
Article
Restricted access - publisher's policyThe present study evaluated the efficiency of a semi-closed, tubular, horizontal photobioreactor (PBR) to treat a mixture of irrigation and rural drainage water, focusing in the removal of different contaminants of emerging ... -
Production of polymers by cyanobacteria grown in wastewater: current status, challenges and future perspectives
(Elsevier, 2020-03)
Article
Restricted access - publisher's policyCyanobacteria are prokaryotic oxygenic phototrophs receiving attention in a wide variety of technological applications such as food and feed supplements and production of valuable polymers. Among these, carbohydrates (e.g. ... -
Volcanic ash as a sustainable binder material: an extensive review
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-03)
Article
Open AccessThe construction industry is affected by the constant growth of populations in urban areas. The demands for cement production has an increasing environmental impact, and there are urgent demands for alternative sustainable ... -
Promotion of full-scale constructed wetlands in the wine sector: comparison of greenhouse gas emissions with activated sludge systems
(Elsevier, 2021-05)
Article
Restricted access - publisher's policyThe aim of this study was to quantify and compare greenhouse gas (GHG) (i.e. carbon dioxide (CO2), nitrousoxide (N2O) and methane (CH4)) emissions from two full-scale winery wastewater and sludge treatment sys-tems (i.e. ... -
Optimization and operation of a demonstrative full scale microalgae harvesting unit based on coagulation, flocculation and sedimentation
(2021-03)
Article
Restricted access - publisher's policyBiomass harvesting is a bottleneck in microalgae culture and microalgae-based wastewater treatment systems. Sedimentation coupled to coagulation and flocculation has been experimentally studied for a long time, however, ... -
Life Cycle Assessment of the mesophilic, thermophilic, and temperature-phased anaerobic digestion of sewage sludge
(2020-11)
Article
Open AccessIn this study the environmental impact of the anaerobic digestion (AD) of sewage sludge within an activated sludge wastewater treatment plant (WWTP) was investigated. Three alternative AD systems (mesophilic, thermophilic, ... -
Scaling-up the anaerobic digestion of pretreated microalgal biomass within a water resource recovery facility
(2020-10)
Article
Open AccessMicroalgae-based wastewater treatment plants are low-cost alternatives for recovering nutrients from contaminated effluents through microalgal biomass, which may be subsequently processed into valuable bioproducts and ... -
Constructed wetlands operated as bioelectrochemical systems for the removal of organic micropollutants
(2021-05)
Article
Restricted access - publisher's policyThe removal of organic micropollutants (OMPs) has been investigated in constructed wetlands (CWs) operated as bioelectrochemical systems (BES). The operation of CWs as BES (CW-BES), either in the form of microbial fuel ... -
Microalgae: A sustainable adsorbent with high potential for upconcentration of indium(iii) from liquid process and waste streams
(Royal Society of Chemistry (RSC), 2020-03-21)
Article
Open AccessIndium (In) is a critical raw material heavily demanded in the optical-electronics industry. With its high supply risk, sustainable technologies are needed to recover In(III) from secondary sources, such as leachates from ... -
A critical review of resource recovery from municipal wastewater treatment plants-market supply potentials, technologies and bottlenecks
(2020-04-01)
Article
Open AccessIn recent decades, academia has elaborated a wide range of technological solutions to recover water, energy, fertiliser and other products from centralised municipal wastewater treatment plants. Drivers for this ... -
Organic matter removal and nitrogen transformation by a constructed wetland-microbial fuel cell system with simultaneous bioelectricity generation
(Elsevier, 2021-01)
Article
Restricted access - publisher's policyMicrobial fuel cells integrated into constructed wetlands have been previously studied. Nevertheless, their application as a suitable treatment for wastewater is still in the developmental stage. In this context, the ... -
Natural pigments and biogas recovery from microalgae grown in wastewater
(American Chemical Society (ACS), 2020-07)
Article
Open AccessThis study assessed the recovery of natural pigments (phycobiliproteins) and bioenergy (biogas) from microalgae grown in wastewater. A consortium of microalgae, mainly composed by Nostoc, Phormidium, and Geitlerinema, known ...
