Explain to everyone about the design principle of multi-media filter

   Multi-media filter refers to a process that uses one or more filter media to effectively remove floating impurities and clarify water. Commonly used filter materials include quartz sand, anthracite, manganese sand, etc., which are mainly used for the removal of water treatment.

The meaning of filtration is that in the water treatment process, filtration generally refers to the process of using quartz sand to clarify water. The porous material used in filtration is called filter material. Quartz sand is a very common filter material. The filter material has granular, Powdery, fibrous, commonly used silica sand, anthracite, activated carbon, magnetite, garnet, ceramics, plastic balls, etc.

The multi-media filter (filter bed) uses two or more media as the media filter of the filter layer to remove impurities in the sewage in the industrial circulating water treatment system, so that the water quality meets the requirements of recycling, especially the effective removal of sedimentation technology The tiny particles and bacteria that cannot be removed also have a certain removal effect on BOD and COD.

   1. Multi-media filter composition

   Multi-media filter is mainly composed of filter body, auxiliary pipeline and valve.

   Among them, the filter body mainly includes the following components: a water distribution unit and a supporting component.

   Second, the basis for the selection of the filter material of the multi-media filter

   1. There must be sufficient mechanical strength to avoid immediate wear and tear during backwashing.

  2. Good chemical stability.

  3. It does not contain harmful and toxic substances that are harmful to human health, and does not contain substances that are harmful to production or affect production.

  4. The choice of filter material is to choose a filter material with large decontamination ability, high production water volume, and good effluent water quality.

In the filter material, jade mainly plays a supporting role. In the filtering process, the gap between each other is stable and the gap is large. In the positive washing process, the filtered water is easy to pass smoothly; similarly, in the backwashing process, the backwash water and The backwash air passes smoothly. According to the conventional arrangement, the jade is divided into four specifications, and the paving method is from bottom to top to become larger and smaller.

   Three, the relationship between the particle size of the filter material and the filling height

  The ratio of the height of the filter bed to the average particle size of the filter material is 800~1000 (design basis), and the size of the filter material particle size is related to the filtration accuracy.
