Application of selectrodialysis for the removal of as from metallurgical process waters: Recovery of Cu and Zn
(2017-12-19)
Article
Open AccessIn this work, selectrodialysis (SED) was used to separate arsenic (As(V)) from copper (Cu(II)) and (Zn(II)) of acidic metallurgical process streams by integrating non-selective and selective membranes. The separation process ... -
Binary fixed bed modeling of phenol/aniline removal from aqueous solutions onto hyper-cross-linked resin (Macronet MN200)
(2012-05-10)
Article
Restricted access - publisher's policyThe sorption performance of hyper-cross-linked Macronet resin (MN200) to remove phenol and aniline from aqueous solution has been evaluated. Fixed bed column experiments were undertaken to obtain the breakthrough curves ... -
Biogas biological desulphurisation under extremely acidic conditions for energetic valorisation in Solid Oxide Fuel Cells
(2014-11-01)
Article
Restricted access - publisher's policyThe most harmful biogas contaminant for energy conversion equipment such as fuel cells is hydrogen sulphide (H2S); thus efficient and cost-effective treatment systems for this compound should be designed and developed. A ... -

(2014-11-01)
Article
Restricted access - publisher's policyBiogas from anaerobic digestion is a powerful renewable fuel that can be used as a feedstock for fuel cell systems. A biogas deep treatment was installed and operated at pilot plant level in a Waste Water Treatment Plant ... -
Cadmium and lead removal from aqueous solution by grape stalk wastes: modeling of a fixed-bed column
(2010-09)
Article
Open AccessGrape stalk wastes generated in the wine production process were used for the removal of cadmium and lead ions from aqueous solutions. The experimental breakthrough curves (BTC) were obtained from fixedbed columns. ... -
Characterization of chromium (III) removal from aqueous solutions by an immature coal (leonardite). Toward a better understanding of the phenomena involved
(2014-01)
Article
Open AccessRemoval of chromium (III) from aqueous solutions by leonardite (a low-cost adsorbent) was studied in a series of batch experiments. Stabilization of the adsorbent material with alginate beads was also investigated. The ... -
Comparative LCA of sewage sludge valorisation as both fuel and raw material substitute in clinker production
(Elsevier, 2013-07-15)
Article
Restricted access - publisher's policyA life cycle assessment to evaluate the environmental impact of urban sewage sludge use as alternative fuel or raw material in clinker production was carried out. In order to quantify in detail the overall environmental ... -
