Description
Gravel is a coarse sedimentary material commonly used in water treatment processes. It consists of small, rounded stones or pebbles, typically made of granite, limestone, or other durable rock types. In water treatment, gravel is employed as a filtration medium in various applications, such as rapid gravity filters, multimedia filters, and packed bed reactors. Its porous nature and large surface area make it an excellent choice for removing suspended particles, sediments, and impurities from water. Gravel acts as a support medium, providing structural stability to the filtration system while allowing water to flow through and facilitating the removal of contaminants. It is often combined with other filtration media, such as sand or activated carbon, to enhance the efficiency of the water treatment process.
