What are the Features of Dual Media Filters?
The main purpose of a sand-anthracite filter, dual media filter, or a multi-media filter, is to remove turbidity and suspended particulates, as small as 10–20 microns. Dual media filters offer very effective particle removal, when a high filtering rate is present.
In this blog, we will discuss about some features of the dual media filters (DMF).
Wastewater treatment using DMF
Wastewater treatment facilities are important since ordinary water contains contaminants,which can be harmful to people, animals, and the environment.Indian wastewater treatment plants use media filtering as an automated technique. Here, the procedures for absorption are both chemical and physical.
Stages of media filtration
The four crucial stages of media filtration are dispersal, sedimentation, blockage, and pouring.
The use of dual media filters is a practical remedy for contaminated water. Thick organic substances, as well as many other pollutants, are thought to be perfectly removed with this technique. However, this approachtotally removes liquefied solids.
Process of wastewater treatment using DMF
Water flows through a medium with slightly smaller pores in a dual media filter. The biggest molecules are released by anthracite. With the aid of the adhesion and straining mix properties of garnet and sand, the subsequent layer removes particles. Dual media filters use an automatic back washing method, to help manage unit efficiency.
From bottom to top, the dual media bed is categorized as follows:
1: This standardized filter media composition enables the sand anthracite filter, to operate for longer periods of time before a backwash is necessary. There are two essential components to a multi-media or sand anthracite filter.
• Composite pressure vessel, with a multiport valve.
•Sand and coal beds.
2: The bottom colleting system and intake distributor are mounted inside the dual media filter. Frontal pipe work and isolation valves are used to enclose the system, from the outside.
3: To prepare the water for various uses, suspended particles are removed with sand, and odours, colours, and other elements are removed with anthracite. The sand-anthracite filter will occasionally backwash, which alters the water flow through the filter.
Important features of dual media filters
• 20 Microns FRP, MSRL, MSEP, and SS,

• There are manual, semi-automated, and automated features available.
Application of DMF or dual media filters
• Side stream cooling tower filtration.
• Water treatment.
• Wastewater treatment.
• Water used in boilers.
Conclusion
In less developed countries, a lack of water is a major factor in the slow rate of population increase, and water pollution is bad for people's health and hygiene. Only a small portion of the world's water, which makes up three-fourths of its total volume, is suitable for human consumption. Therefore, it is important to encourage the reuse of water in industry and agriculture.
Reuse of water is impossible without adequate treatment. As a result, water and wastewater treatment plants are essential. Contact Netsol Water for water and wastewater treatment plant design, construction, and manufacturing.
