Product overview:

Full automatic multi-media filter, also known as mechanical filter, is mainly used to remove suspended substances and solid particles in water. Suspended solids are non colloidal solid substances that are insoluble in water and can precipitate when conditions are appropriate. The filter is used to intercept the suspended solids, and the weight difference before and after the filter medium intercepts the suspended solids is taken as the basis to measure the function of the filter. Generally, filter media with D=0.5-1.0mm are used as filter media. Single layer, double layer and multi-layer filtration can be used according to the impurity composition in water.

Working principle:

Multi media filter (also known as mechanical filter) takes layered anthracite, sand, finely crushed garnet or other materials as the bed. A typical multi media filter is shown in the figure below:

The top layer of the bed consists of light and coarse materials, while the heavy and fine materials are placed at the bottom of the bed. Its principle is to filter by depth - larger particles in the water are removed at the top layer, and smaller particles are removed at the deeper part of the filter medium. Thus, the water quality can reach the standard after coarse filtration.

Performance characteristics:

The multi-media filter can remove large suspended particles in water, thus reducing the SDI value of water and meeting the water quality requirements of deep purification. The equipment has the advantages of low cost, low operation cost and simple operation; The filter material is backwashed, can be used for many times, and has a long service life
