Treating urban storm water runoff

Using compact filtering technology for storm water treatment

In recent years, Denmark has experienced an increase in the intensity of precipitation. In cities across the country, this has also meant a rise in storm water runoff. Without the proper equipment in place to deal with this increase, many combined sewer systems become overloaded. Adapting the Danish wastewater infrastructure to meet this change is essential. In order to help Denmark’s wastewater infrastructure adjust, we tested two filtering technologies: Flexible Fibre Filter Module and Hydrotech Disc Filters. These compact systems allow for decentralised treatment of storm water. Treating storm water results in better water quality in the environment and improves municipal wastewater treatment plant operations.
