In drinking water filtration, wastewater treatment; Filter gravel, natural quartz particles from 1 mm to 32 mm, which are formed as a result of the decomposition of igneous, metamorphic rocks rich in quartz, are used. In filtration, filter gravel and filter sand are used in many water treatment plants to remove ferric (hydr) oxide from water and are changed periodically.
Filter Gravel provides highly effective filtration due to its ability to hold back impurity-containing sediments. Filter grit size varies from 1 mm to 32 mm.
“Filter gravel is produced from natural quartz sands after washing and screening processes in accordance with TS EN 12904 standards and classified in desired dimensions. Filter gravel and quartz sands are insoluble and do not lose mass in acid tests.”
In drinking water treatment plants, filter gravel is gradually placed before the filter sand is placed. It is used as a drainage material around the well in water drillings.
