CHAPTER 5 WATER TREATMENT PLANT
www.cpheeo.gov.inSlow Sand filtration was the first type of porous media filtration used in water treatment. This process is known for its simplicity and efficiency. During the initial operational period of slow sand filters, the separation of organic matter and other solids generates a layer of biological matter on the surface of the filter media.

transportation.ky.govSilt fences have a useful life of one season. Their principal mode of action is to slow and pond the water and allow soil particles to settle with some minor filtration through the fabric. Silt fences are not designed to withstand high heads of water, and therefore should be located where only shallow pools (i.e., 1.5 feet or less) can form.
