Abstract
Technology to treat rare earth element (REE) upstream and midstream wastewater especially acid mine drainage (AMD) is urged to be developed as it was proven current circular economy practice in downstream processes is environmentally unfriendly. This study applied forward osmosis (FO) to treat synthetic AMD containing neodymium (Nd) by using a thin-film composite (TFC) membrane as it is cheaper compared to other membrane technologies that require external pressure. Non-solvent induced phase separation (NIPS) was used to fabricate porous substrate prepared from different polyether sulfone (PES) concentrations (13 wt%, 15 wt%, 17 wt%,19 wt%) and 10 wt% PVP. Then, interfacial polymerization (IP) was done on the substrate for crosslinking of polyamide (PA) thin-film active layer. Intrinsic parameters of the fabricated TFC membranes were studied using a two-stage non-pressurized test. The occurrence of the electric double layer effect was proven in this study which was accountable for the Nd rejection together with the structure of the PA layer. TFC membrane prepared from 15 wt% PES showed the best Nd rejection efficiency with 98.28 % in ALFS orientation due to its high negative surface charge with the PA structure of leaves and nodules.
期刊介绍：
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
