Principle

Different Filtration Media

Water quality management demands a versatile approach, especially when dealing with a variety of impurities. Multi-Media Filters (MMFs) are the cornerstone of sophisticated water treatment processes, offering a customizable solution that caters to a wide spectrum of filtration needs. By utilizing different filter media such as Quartz Sand, Activated Carbon, and Manganese Sand, MMFs are capable of removing a diverse array of contaminants, ensuring the highest water quality for industrial, municipal, and agricultural applications.

Quartz Sand is a classic filtration medium known for its hardiness and effectiveness in removing suspended solids and turbidity from water. Its high purity and mechanical strength make it an ideal first layer in MMFs, acting as a pre-filter to protect subsequent layers from large particle contamination.

Activated Carbon is renowned for its adsorptive qualities, making it an excellent choice for removing organic compounds, chlorine, and odors from water. Its porous structure provides a vast surface area that traps contaminants, ensuring taste and odor improvement, and making it indispensable in the treatment of municipal drinking water and industrial process water.

Manganese Sand is specifically effective in removing iron and manganese, elements commonly found in groundwater sources. These metals can cause staining, pipe blockage, and other water system issues. Manganese sand acts as an oxidizing agent, transforming soluble iron and manganese into insoluble oxides that can be easily filtered out.

How the filter system work?

Multi-media filters (Mechanical filter) use one or more filter media -quartz sand, anthracite, manganese sand, etc. to pass highly turbid water , which are mainly used in water treatment to remove turbidity, soften water, and pre-treatment of pure water. The turbidity of the effluent can reach below 5mg/L.

Product features

1. Application: widely used in water treatment processes and can be used alone, but most of them are used as pre-filtration for advanced water quality treatment (exchange resin, electrodialysis, reverse osmosis).

2. The multi-media filter is a commonly used pretreatment device for deep purification of water quality. Different filter materials can be added according to process requirements.
3. Material: FRP, A3 steel anti-corrosion or rubber lining, and all stainless steel.
There are two types of operation modes: full-automatic and manual.
4. The filter media:
The relative density of anthracite is 1.4-1.6, the particle size is 0.8-1.8mm;
The relative density of quartz sand is 2.6-2.65, and the particle size is 0.5-1.2mm;
In addition to the above two medias, such as manganese sand and magnetite has a relative density of 4.7-5.0 and a particle size of 0.5-4 mm.

Water treatment solutions

By combining these media in a layered bed, MMFs offer a comprehensive filtration solution. The larger particles are trapped by the coarser layers on top, while finer particles are captured by the finer layers below. This graded-bed design allows for more efficient filtration and longer filter runs, reducing backwash frequency and saving on maintenance costs.

Our Multi-Media Filters are designed with flexibility in mind, allowing for the customization of media layers based on the specific impurities present in the water source. This tailored approach ensures that each filtration system operates at peak efficiency, providing clear, safe, and pure water for any application.

Whether you're dealing with industrial wastewater, municipal drinking supplies, or agricultural irrigation systems, our Multi-Media Filters can be configured to meet your unique water treatment challenges. With our expertise and quality products, you can trust that your water filtration requirements are in good hands.
