Schmutzdecke
Schmutzdecke (pronounced: /ʃmʊtsˈdɛkə/) is a term used in water treatment and environmental science. It originates from the German words "Schmutz" (dirt) and "Decke" (cover), literally translating to "dirt cover".
Etymology
The term Schmutzdecke is derived from the German language. It is a compound word, combining "Schmutz" meaning dirt or filth, and "Decke" meaning cover or blanket. This term is used to describe the layer of particulate matter that forms on the surface of slow sand filters used in water treatment processes.
Definition
In the field of water treatment, the Schmutzdecke is a layer that forms on the surface of the sand in a slow sand filter. It consists of a biofilm of bacteria, algae, fungi, protozoa, and other microorganisms, along with trapped particulate matter. This layer plays a crucial role in the filtration process, as it helps to remove pathogens and other contaminants from the water.
