Fouling mitigation in tubular membranes by 3D-printed turbulence promoters

Tubular MFI Zeolite Membranes Made by In-Situ Crystallization

Polycrystalline MFI zeolite membranes were prepared on α-alumina tubular support by hydrothermal treatments at 413 K. The synthesized zeolite membranes were characterized by XRD, SEM and single gas permeation. The influence of hydrothermal treatment steps and the calcination time on the zeolite layer formation were investigated. MFI zeolite membrane prepared by four subsequent hydrothermal ...

Fouling and Fouling Mitigation on Heat Exchanger Surfaces

Electro-Conductive Membranes for Permeation Enhancement and Fouling Mitigation: A Short Review

The research on electro-conductive membranes has expanded in recent years. These membranes have strong prospective as key components in next generation water treatment plants because they are engineered in order to enhance their performance in terms of separation, flux, fouling potential, and permselectivity. The present review summarizes recent developments in the preparation of electro-conduc...

NOM Rejection by, and Fouling of, NF and UF Membranes

OBJECTIVES: The performance of spiral-wound nanofiltration (NF) and ultrafiltration (UF) membranes was investigated in terms of natural organic matter (NOM) rejection and associated NOM fouling. The study objectives focused on • demonstrating the effects of both hydrophobic and electrostatic interactions between NOM components and the membrane surface • determining influential factors (water qu...
