The selection of an optimal cleaning strategy for PVDF MBR modules is contingent upon various factors, including the type and severity of fouling, operational conditions, and environmental considerations.

Nanofiltration Membrane Fouling Mitigation Strategies

Fouling is a common problem faced in ultrafiltration membranes due to the gradual accumulation of particulates on the membrane surface and/or within its pores. This build-up leads to reduced permeate flux, increased operational costs, and ultimately, compromised membrane performance. To address this critical issue, various fouling mitigation strategies have been explored.

Effective strategies often involve a combination of approaches targeting different aspects of the fouling process. These include:

Pre-filtration to remove large molecules from the feed stream before it reaches the membrane.
Surface Modification to enhance membrane hydrophilicity, reduce fouling susceptibility, and facilitate descaling.
Process Control to minimize shear stress on the membrane surface and reduce concentration polarization.

Continuous research in membrane materials, manufacturing techniques, and operating strategies hold great opportunity for achieving effective fouling control in ultrafiltration membranes.
