- Abstract
- Membrane fouling and its control is one of the most critical parameters in the application of membrane processes. The degree of fouling depends on the application and on industrial scale, fouling is often observed as reduction in plant capacity over time. One approach to reduce fouling for the pressure driven processes microfiltration and ultrafiltration is to use hydrophilic membranes. This paper will show two examples of the development and use of hydrophilic membranes – ETNA and UFX membranes - for challenging microfiltration and ultrafiltration applications and will provide an overview on recent and future developments regarding hydrophilic membranes.

The degree of fouling depends on the application and on industrial scale, fouling is often observed as reduction in plant capacity over time. One approach to reduce fouling for the pressure driven processes microfiltration and ultrafiltration is to use hydrophilic membranes. This paper will show two examples of the development and use of hydrophilic membranes – ETNA and UFX membranes - for challenging microfiltration and ultrafiltration applications and will provide an overview on recent and future developments regarding hydrophilic membranes.
The ETNA membrane is a surface-modified PVDF membrane with permanently hydrophilic properties on a polypropylene support. One of the key application areas for this membrane is the separation of oil-water mixtures, an application area which is driven by the increasing demand for efficient oil-water separation, e.g. produced water in the oil and gas industry, process water in the petrochemical industry and bilge water in the marine industry.
The UFX membrane is a permanently hydrophilic polysulphone based membrane reinforced on a polypropylene support. The membrane has established itself as the standard for concentration and purifications of industrial enzymes but it should also have potential in the concept of future biorefineries in particular for the concentration and purification of hemicellulose.
One current trend is the use of cellulose, a sustainable membrane material, which can either be used directly, or as regenerated cellulose, e.g. the European NanoSelect project which is aiming at the development of low fouling and adsorption membranes based on cellulosic fibrils, and the development of a new generation of regenerated cellulose membranes by Alfa Laval is in progress.
Overall, the development and availability of hydrophilic membranes can reduce the fouling challenges in a wide range of industries.
