Schmutzdecke: from German, meaning "dirt cover."

The complex biological layer formed on the surface of a slow sand filter, which provides effective purification in potable water treatment, the underlying sand being the support medium for this biological treatment layer. The composition of any particular schmutzdecke varies, but will typically consist of a gelatinous biofilm matrix of bacteria, fungi, protozoa, rotifer and a range of aquatic insect larvae. Hence, sometimes "muck" can do good things!
