Abstract

A system for membrane fouling control configured to run one or more filter cycles, wherein each filter cycle of the one or more filter cycles includes an operation mode and a cleaning mode. The system includes: a first conduct portion; a second conduct portion; a membrane arranged between the first conduct portion and the second conduct portion. The membrane is configured in the operation mode to filter a liquid to be filtered by conducting it from the first conduct portion to the second conduct portion. A fouling control means filled with fouling control particles is added in the operation mode in the first conduct portion so that a dynamic protective layer is formed on the membrane. The fouling control particles are mineral particles based on calcium and/or magnesium.
