Development of a two-stage membrane filtration process in combination with enzymatic reactions to remove micropollutants from water

Year: 2025

Type: article

Abstract: In this study, a novel two-stage membrane filtration process was developed and tested in combination with enzymatic reactions to remove micropollutants from water. The heart of the test cell built is a reaction chamber that is separated by two membranes (ultrafiltration and nanofiltration membrane). The reaction chamber contains enzymes that break down micropollutants (here: Remazol® Brilliant Blue R). Both membranes keep the enzyme Laccase in the reaction chamber, while the pressurized ultrafiltration membrane prevents the enzymes from entering the raw water. Experiments with the test cell have shown that the nanofiltration membrane completely prevents the enzymes from entering the permeate and partially retains the micropollutant to be removed. With the help of a CFD-based analysis, it was possible to make statements about the future geometry of the test cell. The module developed for water treatment is new and has not been described in any publication to date.
