Anaerobic digestion of solid slaughterhouse waste (SHW) at laboratory scale: Influence of co-digestion with the organic fraction of municipal solid waste (OFMSW)
Abstract Mesophilic anaerobic digestion of slaughterhouse waste (SHW) and its co-digestion with the organic fraction of municipal solid waste (OFMSW) have been evaluated. These processes were carried
Processes for the elimination of estrogenic steroid hormones from water: a review.
This paper aims to review the different processes and treatments that have been applied for the elimination of E1, E2, E3 and EE2 from water and addresses physical, biological and advanced oxidation processes (AOP) addressed.
Elimination of organic water pollutants using adsorbents obtained from sewage sludge
Sewage sludge valorisation must be the preferred management solution for a residue which minimising does not keep with a desirable improvement on wastewater treatment. This research work deals with
Adsorptive removal of pharmaceuticals from water by commercial and waste-based carbons.
In order to evaluate the influence of water solubility, log Kow, pKa, polar surface area and number of hydrogen bond acceptors of pharmaceuticals on the adsorption parameters, multiple linear regression analysis was performed.
Silica coated magnetite particles for magnetic removal of Hg2+ from water.
Under the experimental conditions used, the materials reported here displayed high efficiency for Hg(2+) uptake (74%) even at contaminant levels as low as 50 μg l(-1), therefore these eco-nanomagnets show great potential for the removal of heavy metal ions of polluted water, via magnetic separation.
Co-combustion of different sewage sludge and coal: a non-isothermal thermogravimetric kinetic analysis.
This work illustrates how thermogravimetric analysis may be used as an easy rapid tool to asses, not only mass loss, but also kinetics of the co-combustion of sewage sludge and coal blends.
Adsorption of heavy metals onto sewage sludge-derived materials.
Although AS displayed higher capacity, both PS and AS were able to adsorb these metals and the preferential order was equal: Hg(II)>Pb( II)>Cu(II]>Cr(III)>Cr (III).
Mercury pollution in Ria de Aveiro (Portugal): a review of the system assessment
Results indicate that the main mercury contamination problems in the Ria de Aveiro are confined to the Laranjo bay, and mercury export to the coastal waters and its impact on the nearshore compartments (water column, sediment and biota) are low.
Anaerobic digestion and co-digestion of slaughterhouse waste (SHW): influence of heat and pressure pre-treatment in biogas yield.
The results indicate that the temperature and the high pressure of the pre-treatment applied favoured the formation of compounds that are refractory to anaerobic digestion, leading to instability and inhibition of the degradation process.
Application in fixed-bed systems of adsorbents obtained from sewage sludge and discarded tyres
Abstract A feasibility study is made with the use of adsorbents produced from sewage sludge and the solid residue of pyrolysed tyres in fixed-bed adsorption. The study was focused on dyeing
