Belloni, C. (author), Korving, L. (author), Witkamp, G. J. (author), Brück, E.H. (author), de Jager, P. (author), Dugulan, A.I. (author)Hybrid anion exchange adsorbents (HAIX) seem promising to prevent eutrophication and recover phosphate (P). HAIX consist of an anion exchange resin (AIX) backbone, promoting anion physisorption (outer-sphere complex), impregnated with iron (hydr)oxide nanoparticles (NPs), for selective P chemisorption (inner-sphere complex). In this work, for...journal article 2023

Keshavarz, Fatemeh (author), Kavun, V. (author), van der Veen, M.A. (author), Repo, Eveliina (author), Barbiellini, Bernardo (author)Selective separation of rare earth elements (REEs) from solutions of mixed heavy and light metals by solid adsorbents is an important challenge in the fields of water treatment and metal recovery. The main challenge is water instability of many adsorbents, specifically metal–organic frameworks (MOFs), and their low selectivity. Grafting...journal article 2022

Zheng, X. (author), Jiang, N. (author), Zheng, Huaili (author), Wu, Yuyang (author), Heijman, Sebastiaan (author)One framework type of high-silica zeolite only can effectively remove a limited range of organic micropollutants (OMPs) from water. In order to extend the OMP removal range, different types of high-silica zeolites need to be combined in the adsorption process. In this study, Mordernite (MOR) and ZSM-5 (MFI) high-silica zeolite powders were mixed...journal article 2021

Jiang, N. (author), Shang, R. (author), Heijman, Sebastiaan (author), Rietveld, L.C. (author)High-silica zeolites can be used for adsorption of organic compounds (OCs) from water. The adsorption efficacy could vary with the properties of OCs, as well as the porous and surface features of high-silica zeolites. In this study, the adsorption of triclosan, trichlorophenol (TCP) and phenol by ten high-silica zeolites were investigated. The...journal article 2020

van Linden, N. (author), Bandinu, G. (author), Vermaas, D.A. (author), Spanjers, H. (author), van Lier, J.B. (author)Removal of ammoniacal nitrogen from residual waters traditionally relies on energy-consuming biochemical processes, while more novel alternative strategies focus on the recovery of total ammoniacal nitrogen for the production of fertilisers or the generation of energy. The recovery of total ammoniacal nitrogen as gaseous ammonia is more...journal article 2020

Kramer, F.C. (author), Shang, R. (author), Scherrenberg, S. M. (author), Rietveld, L.C. (author), Heijman, Sebastiaan (author)One of the perceived benefits of ceramic membranes is their robustness, which makes them suitable for treating high organic load waste streams. In particular, ceramic tight ultrafiltration (tUF) and nanofiltration (NF) form an important barrier against small colloids and organic molecules. In order to achieve this barrier, the quality of the...journal article 2019
