Worldwide, water treatment plants use filter media in the process of treating water from natural sources and making it drinkable before transporting it to residential localities. The main types of media which are used commonly are anthracite, sand, garnet and support gravel. Filtration may be single media filtration or multi media filtration. The advantages of multimedia filtration are that it gives higher flow rates, consumption of backwash water is reduced and the filtration runs between backwashes is longer. However it is important to replace filter media at regular intervals to maintain the quality of water and there are numerous contractors for water plant media filter replacement who not only replace filter media but are also experts in troubleshooting any other problems which mat arise in filtration plants.
