Nanofiltration for recovery of spent ion exchange brines [PDF]

, 2003
Nanofiltration has been successfully applied to the recovery of spent anion exchange brines but not yet for spent cation exchange brines. Polymeric nanofiltration membranes have ionisable carboxyl and amine functional groups and tend to carry a negative ...

Phosphorus removal using nanofiltration membranes

Water Science and Technology, 2011
A high concentration of phosphorus in wastewater may lead to excessive algae growth and de-oxygenation of the water. In this work, nanofiltration (NF) of phosphorus-rich solutions is studied in order to investigate its potential in removing and recycling phosphorus. Wastewater samples from a pulp and paper plant were first analyzed.

Mechanistic Insights and Performance Advancements in Flow Capacitive Deionisation for Sustainable Energy Conversion

Electrochemical Science Advances, Volume 6, Issue 4, August 2026.
ABSTRACT Flow capacitive deionisation is an advanced electrochemical technology for water purification and energy‐related applications. It represents a viable alternative to conventional desalination methods due to its low operating voltage, continuous electrode regeneration, and stable performance under moderate‐to‐high salinity conditions. The use of

Simulation‐Based Design and Evaluation of an Alkaline Direct Glycerol Fuel Cell Stack With Integrated Purification

Fuel Cells, Volume 26, Issue 4, August 2026.
ABSTRACT Direct glycerol fuel cells (DGFCs) are a promising technology, but scaling them remains a challenge due to persistent technological and economic limitations. In this context, process simulation and modeling emerge as crucial tools. This study addresses the implementation of a conventional alkaline DGFC stack model in Aspen Plus and proposes a ...

Efficient Trapping and Degradation of Polyethylene Terephthalate Nanoplastics Using Enzyme‐Functionalized Bowl‐Shaped Janus Particles

Small Structures, Volume 7, Issue 8, August 2026.
A “capture‐and‐degrade” strategy is developed using enzyme‐functionalized bowl‐shaped Janus particles for efficient removal of PET nanoplastics. The hydrophobic concave cavity enables selective trapping of nanoparticles, while immobilized HotPETase‐LCI promotes in situ degradation.
