1、 Product function

Multi media filtration is one of the means to remove suspended solids and peculiar smell in water. It is an important unit in water purification, advanced sewage treatment, sewage reuse and water supply treatment. Its function is to further remove the pollutants in the water. It achieves the purpose of water purification through the interception, sedimentation and adsorption of filter materials.

2、 Scope of application

1. For industrial water, domestic water and municipal water supply systems requiring effluent turbidity ≤ 5mg / L and meeting drinking water quality standards;

2. Removal of suspended solids and solids in industrial sewage;

3. It can be used as pretreatment equipment in ion exchange softening and desalination system and coarse filtration equipment for industrial water supply with low water quality requirements;

And used in swimming pool circulating treatment system, cooling circulating water purification system, etc.

3、 Product features

1. Multi filter layer structure, which can realize on-line backwashing.

2. Stainless steel, carbon steel and FRP can be selected according to the system water pressure and tank material.

5、 Working principle

The multi-media filter uses quartz sand and anthracite as the filter medium. The filter material has the advantages of high strength, large treatment flow and   stable effluent quality. The function of quartz sand is mainly to remove suspended solids, colloids, sediment and rust in water. The water pump is used to pressurize the raw water to pass through the filter medium to remove the suspended solids in the water, so as to achieve the purpose of filtration.
