Media Filter:Also known as a mechanical filter, it is a typical multi-media filter with a bed layer composed of layered materials such as anthracite, sand, fine crushed garnet, or other media.
Depending on the filter media and function, various types are available, including quartz sand filters, iron and manganese removal filters, activated carbon filters, fluoride removal filters, fiber ball filters, and others.
Filter vessels are available in different materials, including FRP (Fiber-Reinforced Plastic), carbon steel, and stainless steel.
The filter unit primarily comprises the following components: vessel shell, water distribution assembly, support assembly, backwash air header, filter media, and external air release valve, among others.
A multi-media filter utilizes one or more types of filtration media to pass high-turbidity water through a bed of granular or non-granular materials under pressure, effectively removing suspended impurities and clarifying the water. Commonly used filter media include quartz sand, activated carbon, anthracite, and manganese sand. It is widely used for turbidity removal in water treatment, softening, and as pretreatment for pure water systems, with effluent turbidity capable of reaching below 3 NTU.
