Hydrogel membrane composite reduces fouling and retains ammonium efficiently

Environmental Chemistry Letters, Journal Year: 2024, Volume and Issue: 22(4), P. 1615 - 1621

Published: March 1, 2024

Abstract The recovery of pure water and valuable substances from wastewater is a major challenge in the context circular economy, requiring advanced separation methods. However, actual membrane techniques such as forward osmosis are limited by fouling selectivity. Here, we synthesized composite membranes crosslinking polyvinyl alcohol hydrogel, using both glutaraldehyde borax agents, on top cellulose ester membranes. We tested these model real wastewater. Results show that retain ammonium effectively, maintain surface electroneutrality, exhibit remarkable resistance to organic biological contaminants. This explained high hydrophilicity after application hydrogel layer.

Nanofiltration PVP Membrane with Gradient Cross-Linking for Efficient Polycyclic Aromatic Hydrocarbons Removal

ACS Omega, Journal Year: 2024, Volume and Issue: 9(5), P. 5265 - 5272

Published: Jan. 25, 2024

Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants that may contaminate various water sources and pose serious dangers to human health the environment. Due their capacity for size-based separation, nanofiltration membranes have become efficient instruments PAH removal. However, issues such as membrane fouling ineffective rejection still exist. To improve while reducing problems, this work created a new gradient cross-linking poly(vinylpyrrolidone) (PVP) membrane. The technique enhanced performance antifouling characteristics of results demonstrated highest flow was achieved at 0.15% SDS-PVP There is trade-off between flux salt since increases with SDS owing growth big pores. reduced 0.25% poor dispersion. prepared showed removal efficiencies compounds. PVP has potential be used in several treatment applications, improving quality, preserving

Construction of a Covalent Crosslinked Membrane Exhibiting Superhydrophilicity and Underwater Superoleophobicity for the Efficient Separation of High-Viscosity Oil–Water Emulsion Under Gravity

Molecules, Journal Year: 2025, Volume and Issue: 30(8), P. 1840 - 1840

Published: April 19, 2025

The separation of high-viscosity oil–water emulsions remains a global challenge due to ultra-stable interfaces and severe membrane fouling. In this paper, SiO2 micro–nanoparticles coated with polyethyleneimine (PEI) were initially loaded onto stainless steel substrate. This dual-functional design simultaneously modifies surface roughness wettability. Furthermore, covalent crosslinking network was created through the Schiff base reaction between PEI glutaraldehyde (GA) enhance stability membrane. exhibits extreme wettability, superhydrophilicity (WCA = 0°), underwater superoleophobicity (UWOCA 156.9°), enabling gravity-driven pump oil 99.9% efficiency flux 1006 L·m−2·h−1. Moreover, molecular dynamics (MD) simulations demonstrate that SiO2-PEI-GA-modified promotes formation stable hydration layer, reduces oil–layer interaction energy by 85.54%, superior oleophobicity compared unmodified SSM. Efficiency is maintained at 99.8% after 10 cycles. study provides scalable strategy combines hydrophilic particle modification, effectively addressing trade-off performance longevity in treatment viscous emulsions.
