Potential recovery of phosphorus in the portuguese urban sector: an opportunity...

Lima, Aías; Ramísio, Paulo J.; Figueiredo, Sónia; Caetano, Nídia

Phosphorus (P), which plays an important role in the food sector, is facing a global shortage. It has been identified as one of the materials at risk of scarcity, and in 2014 was declared as a critical raw material by the European Union. Studies indicate that the only way to close the P loop in the European Union is to recycle P from waste streams back into the food chain. In Portugal, the loss of P after waste...


Evaluating territorial metabolism for phosphorus (P) valorization from waste in...

Lima, Aías; Caetano, Nídia; Figueiredo, Sónia; Ramísio, Paulo J.

Phosphorus (P) has been identified as one of the materials at risk of scarcity, and in 2014 was included in the critical raw material list by the European Union, where the vulnerability in imports is up to 90%. In view of the European regulatory picture around the circularity of P, there is great potential to reduce the consumption of primary material, through the recovery from wastes of specific sectors, such ...

UALGORITMO, a new instrument of the University of Algarve for scientific outreach

Bragança, José; Figueiredo, Sónia; Rego, Carla Alexandra; dos Reis Conceição, Filomena; Jesus, Saúl Neves de

Researchers at Universities generate and convey the knowledge acquired through communications in specialized (inter)national journals and congresses. An effort to share the scientific achievements with the general public is extremely important. For this purpose, we have launched the UALGORITMO, a journal freely accessible online, written in lay Portuguese language by Researchers of the University of the Algarve...


Vermiculite as a potential functional additive for water treatment bioreactors ...

Węgrzyn, Agnieszka; Tsurtsumia, Avtandil; Witkowski, Stefan; Freitas, Olga; Figueiredo, Sónia; Cybińska, Joanna; Stawiński, Wojciech

A new adsorbent that combines mineral vermiculite with the yeast Saccharomyces cerevisiae, was used for Cd2+ removal. The influence of vermiculite presence on the toxic effects of Cd2+ to Saccharomyces cerevisiae yeast was evaluated as a function of the microorganisms' respiratory activity (CO2 production). The Cd2+ toxicity increased with prolonged exposure time reaching the LC50 value of 857 and 489 mg L−1 af...


Fluoxetine Removal from Aqueous Solutions Using a Lignocellulosic Substrate Col...

Silva, Andreia; Sousa, Juliana; Hultberg, Malin; Figueiredo, Sónia; Freitas, Olga; Delerue-Matos, Cristina

One of the main challenges in both the design of new wastewater treatment plants and the expansion and improvement of existing ones is the removal of emerging pollutants. Therefore, the search for economic and sustainable treatments is needed to enhance the removal of pharmaceuticals. The potential of a lignocellulosic substrate colonized by Pleurotus ostreatus, a waste from mushroom production, to remove fluox...


Continuous adsorption studies of pharmaceuticals in multicomponent mixtures by ...

Puga, Antón; Moreira, Manuela M.; Pazos, Marta; Figueiredo, Sónia; Sanromán, M. Ángeles; Delerue-Matos, Cristina; Rosales, Emilio

In this study, the adsorption of a multicomponent mixture of active pharmaceutical compounds, such as Venlafaxine (VLX), Trazodone (TRZ) and Fluoxetine (FLX), was studied in a biochar fixed-bed column. The selection of appropriate biochar (eucalyptus, grapevine cane and holm tree biochar) as an adsorbent was carried out through batch assays. An insight into the adsorption mechanism and its correlation with the ...


Fluoxetine and Nutrients Removal from Aqueous Solutions by Phycoremediation

Silva, Andreia; Fernandes, Diana F.; Figueiredo, Sónia; Freitas, Olga; Delerue-Matos, Cristina

The tertiary treatment using microalgae offers an attractive alternative to the removal of low but relevant concentrations of pharmaceuticals from domestic wastewaters. The removal of fluoxetine from aqueous solutions by living and non-living (lyophilized) Chlorella vulgaris was assessed. The determination of the pH at the point of zero charge, Fourier transmittance infrared analysis, and scanning electron micr...


Removal of diclofenac and sulfamethoxazole from aqueous solutions and wastewate...

Soares, Cristina; Correia-Sá, Luísa; Paíga, Paula; Barbosa, Carlos; Remor, Paula Verônica; Freitas, Olga; Moreira, Manuela M.; Nouws, Henri

The three-dimensional (3D) electrochemical treatment process was studied for the removal of two pharmaceuticals, diclofenac (anti-inflammatory) and sulfamethoxazole (antibiotic), in mono and bi-component systems. Adsorption and conventional two-dimensional electrochemical processes were initially studied and then combined to develop the 3D process. The influence of different operating parameters on the removal ...
