Multi Media Filters are used for purpose of removing suspended solids, turbidity and impurities like iron and manganese. System is generally consisting of different sized gravels and anthracite inside the body. Sometimes special filling materials will be used according to water quality to be filtered. For example, for more turbid waters or surface water filtration like river or seawater,
turbidexantharicite or garnet - turbidex - anthracite combination will be used. Second duty of Multi Media Filters is to protect the equipment that will be located downstream. Multi Media Filters are used as a pre-treatment step for process water and drinking water applications or sometimes used for removal of turbidity coming from wastewater treatment systems.
