As water is passed through the slow-sand filter, some of the bacteria will be trapped within the spaces between the sand, and water will continue to pass through. Trapped bacteria will then contribute to the biofilm layer, the schmutzedecke. The most important aspect of a slow-sand water filter is the biofilm layer.
