Biological infiltration

A biological infiltration plant can be used to treat rainwater so that the water can subsequently seep down into the ground or be led via tunnelways to an adjacent watercourse or harbour. The filter in a biological infitration plant can remove or degrade heavy metals and other harmful substances in the water. The process takes place using a biological substrate with microorganisms. The plant runs on its own without adjustment and can be used underground.

This technology was used in a building project in Postdam, Germany. For more about this, see the link to the right.
