Ammonia valorization by liquid–liquid membrane contactors for liquid fertilizers production: experimental conditions evaluation
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-06-27)
Article
Open AccessLiquid–liquid membrane contactors (LLMCs) were studied as a sustainable technology for ammonia recovery from wastewater. Ammonia can be valorized by LLMCs as a potential nutrient and produce liquid fertilizers. Thus, this ... -
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 ... -
Arsenic impact on the valorisation schemes of acidic mine waters of the Iberian Pyrite Belt: Integration of selective precipitation and spiral-wound nanofiltration processes
(2021-02-05)
Article
Open AccessArsenic and selenium presence in acid mine waters (AMWs) limits their disposal due to environmental regulations. The focus to solve the economic infeasibility is directed to sustainable solutions, promoting resource recovery. ... -
