Caption: Water treatment plant. Part of the membrane filter system at a water treatment plant. During this stage of water treatment, known as microfiltration, water is passed through a system of fine membranes. This method removes small organisms, which may be parasitic or toxic when ingested by humans, without using pollutant chemicals. Photographed in Etrembieres, Annemasse, France, in 2007.
