The use of membrane technology in the treatment Acid Mine Drainage (AMD) can result reduction chemical usage and sludge production making process more environmentally friendly. This study deals with optimization filtration performance AMD using two nanofiltration (NF) membranes (NF99 DK) one reverse osmosis (RO). All were used various tests treating a model solution at different concentration levels order to cover actual found mining industry. main parameters which studied determine optimal...
Acid mine drainage (AMD) is recognized as one of the more critical environmental problems in mining industry, with potential severe contamination surface and groundwater, well soils. Different conventional methods are used to treat AMD such lime neutralization, which added raise pH then precipitate dissolved toxic heavy metals. In addition a high concentration sulphate, sludge produced by this process has no economic value be disposed large areas land. Nanofiltration (NF) membranes new...
Abstract Mine waters, rich in sulphate, acid and different metal species, are an environmental risk of great importance. Untreated mine waters released into the environment influence complete ecosystems can reduce species plant animal life drastically from thousands to some microbial algae species. Hence, treated before by state-of-theart procedures such as lime treatment or constructed wetlands which focusing on future legislation will not meet discharge criteria especially for sulphate....
Abstract Collagen is increasingly used as material for medical devices because of its excellent biocompatibility. To achieve long‐term durability, the collagen materials are dried and subsequently sterilized. Most common sterilization methods unsuitable they cause denaturation. Currently, only ethylenoxide or γ irradiation preserves microscopic macroscopic structure. However, both require high safety standards include risk uncontrolled crosslinking cleavage protein chains. Here,...
Abstract Ceramic nanofiltration membranes were successfully tested and piloted for the treatment of oily salty water from oil sand mining in Alberta, Canada. The showed a stable behavior over two years operation. complete removal suspended solids as well reduction multivalent ions enable use recycle tailing ponds to prepare boiler feed water. In high salt concentration like waste potash dependency retention on composition was observed. High MgSO 4 even at achieved.
The winning of critical raw materials from secondary resources, e.g., abandoned mines, mining residues, electronic waste or low-grade ores, is a potential source with promising outcomes due to innovative and more efficient extraction methods. research education mine “Reiche Zeche” at the TU Bergakademie Freiberg, Germany offers scientific lab in real application environment for an in-situ bioleaching section sulfide ore vein on-site associated membrane downstream processing. evaluation...
Photochemical advanced oxidation processes (AOPs) utilising different Fenton systems were investigated in laboratory-scale experiments for the degradation of polyethylene glycol (PEG). The results study showed that rate PEG was strongly accelerated by homogeneous system, and this proved to be advantageous comparison heterogeneous system. Between photo-Fenton systems, process reached highest removal organic compound, due enhanced reduction efficiency Fe(III) Fe(II) under UV-irradiation....
New value-adding applications of spent grain, a co-product brewhouse operations, are considered in the context sustainable circular economy. Previous studies have focused on compounds remaining solid phase grain. However, depending dewatering process, separated water also contains relevant fractions nutritionally and physiologically valuable including proteins, carbohydrates polyphenols. Accordingly, work reported here considers two presents detailed view substances especially those from...
A hybrid process of forward osmosis (FO) in combination with thermal regeneration the draw solution is proposed and investigated experimentally. On side solution, a surfactant water emulsion contacting FO membrane. The solubility non-ionic surfactants exceptional that it decreases at elevated temperatures. Depleted surfactant/water can thus easily be separated into an aqueous phase (product water) surfactant-rich (regenerated solution) by increasing temperature order to induce liquid...
Abstract Die Gewinnung sekundärer Rohstoffe ist nicht allein aus Gründen der Weltmarktsituation relevant, auch die Ressourceneffizienz gebietet Nutzung von Deponien, Altablagerungen und Armerzlagerstätten als Rohstoffquellen im Sinne Nachhaltigkeit. Der vorliegende Artikel zeigt Einsatzpotenziale Biohydrometallurgie effizientes Verfahren Wertstoffmobilisierung Rahmen derartiger Rohstoffpotenziale auf widmet sich weiterhin Membrantrenntechnik zur Separation gelöster Wertstoffe...
