Understanding the effects of the origin, occurrence, monitoring, control, fate and removal of siloxanes on the energetic valorization of sewage biogas - A review
(2015-08-14)
Article
Accés obertThis paper reviews the effects of the origin, occurrence, monitoring, control, fate and removal of siloxanes on the energetic valorization of sewage biogas, which can be severely compromised by its volatile organic silicon ... -
Use of nutrient-enriched zeolite (NEZ) from urban wastewaters in amended soils: Evaluation of plant availability of mineral elements
(Elsevier, 2020-07-20)
Article
Accés obertThe usefulness of a nutrient-enriched zeolite (NEZ) obtained from simultaneous ammonium (NH4+) and phosphate (PO43-) recovery from urban wastewaters was evaluated as soil amendment through the early growth of sunflower ... -
Valorisation of Ca and Mg by-products from mining and seawater desalination brines for water treatment applications
(2014-06-01)
Article
Accés restringit per política de l'editorialBACKGROUNDBrines from the drainage of potash mine tailings and from seawater reverse osmosis (SWRO) desalination were previously evaluated as sources of NaCl for the chlor-alkali industry. Valorisation of NaCl as raw ... -
Valorisation of N and P from waste water by using natural reactive hybrid sorbents: Nutrients (N,P,K) release evaluation in amended soils by dynamic experiments
(Elsevier, 2018-01-15)
Article
Accés obertThe removal of nutrients (nitrogen (N), phosphorous (P)) from waste water has become a resource recovery option in recent regulations worldwide, as observed in the European Union. Although both of these nutrients could be ... -
Valorisation options for Zn and Cu recovery from metal influenced acid mine waters through selective precipitation and ion-exchange processes: promotion of on-site/off-site management options
(2021-04)
Article
Accés obertAcid mine waters (AMWs), generated in the processing of polymetallic sulphides, contain copper and zinc as the main valuable transition metal ions, which are typically removed by liming, due to their great environmental ... -
Valorization of ammonia concentrates from treated urban wastewater using liquid–liquid membrane contactors
(2016-05-21)
Article
Accés obertThe removal of ammonium from tertiary effluents by zeolites generates basic ammonia concentrates (up to 1–3 gNH3/L in 1–2 g NaOH/L). This study evaluates the use of hollow fibre liquid–liquid membrane contactors (HFMCs) ... -
