Water filtration by gravity - how it works

The system of gravity filtration is a type of filtration system used to purify water. This system uses gravity to pass the water through different successive filters to eliminate impurities and contaminants. The gravity filtration system is generally composed of Several tanks or bins arranged in series. The first tank contains the water to be treated, which is then pumped or paid in the second tank, where it passes through a filter to eliminate suspended particles. L'filtered water is then transported to the third tank, where it passes through another filter to eliminate microorganisms, bacteria and other contaminants. This process can be repeated several times until water is clean enough to be used or stored. The gravity filtration system is often used to Purify rainwater or spring water before making it drinkable or making domestic uses.
