The multi-media filter is a water filtration system that uses multiple layers of filter media to remove particles and impurities from water. Unlike single-media filters that use only one filter material, multimedia filters combine different materials, each with a specific function, to achieve more efficient filtration. For example, quartz sand removes suspended matter from water, activated carbon decolorizes and removes suspended matter from water, manganese sand removes iron and manganese and suspended matter from water, fiber balls and walnut shells remove oil from water, etc. The most common multimedia filter consists of sand and anthracite as the filtration media. The sand has smaller grains and is heavier than the anthracite. This ensures that the sand layer settles beneath the anthracite and provides finer filtration. A well operated Multimedia Filter can remove particulates down to 20 microns. This multi-layered approach allows multi-media filters to remove a wide range of particle sizes, from large sediments to fine particulates, resulting in cleaner and clearer water.

1.Filter Tank: This component will house the filtration media, it is either stainless steel, FRP or epoxy coated steel. Metallic tanks can handle higher temperatures and pressure
2. Media: This is the filtration media that includes different layers of gravels, quartz sand, and anthracite. This will depend on the quality of the filtered water that is needed.
3. Internal upper and bottom distributors: The bottom distribution system will prevent the media from escaping, while the upper distribution system will distribute the flow harmonically during the service cycle. The materials of construction can either be schedule PVC or stainless steel. If your application has a high temperature water, we recommend stainless steel internals, tank and face piping.
4. Valves: The valves open and close according to the different cycles. They could be automatic electric or pneumatic valves for automatic water filters, or manual valves for manual filters. For seawater, it is recommended to use nonmetallic valves. Some industries do not allow electric valves.
5. Controller: This component will control the automation of your filter. This could be a PLC. This is usually a preference based on the main control in the facility or the building.
6. Face piping: Face piping will connect all valves that control the different cycles. It could be schedule PVC, stainless steel or epoxy coated carbon steel. The material of the piping depends on the temperature or operating pressure, and if it’s an indoor or outdoor application.
