Multi-media filters, also known as mechanical filters, are mainly used to remove suspended matter and solid particles from water. Suspended solids are non-colloidal solid materials that are insoluble in water and which can precipitate when conditions are suitable. The filter is used to intercept the suspended solids, and the weight difference before and after the filter medium intercepts the suspended solids is used as a basis for measuring the function of the filter. The filter medium generally uses a filter medium of D=0.5-1.0 mm. According to the impurity component in the water, single layer filtration, double layer filtration and multi-layer filtration can be used.
(1) Working principle
Multi-media filters (also known as mechanical filters) are beds made of layered anthracite, sand, finely divided garnet or other materials. A typical multi-media filter is shown in the figure:
The top layer of the bed consists of light and coarse grade materials, while the heavy and fine grade materials are placed in the lower part of the bed. The principle is to filter by depth – larger particles in the water are removed at the top layer and smaller particles are removed deeper in the filter media. Thereby the water quality reaches the standard after coarse filtration.
(2) Performance characteristics
The multi-media filter removes large particles of suspended solids in the water, thereby reducing the SDI value of the water and meeting the water quality requirements for deep purification. The device has the advantages of low cost, low operating cost and simple operation; the filter material is backwashed, can be used multiple times, and the filter material has a long service life.
(3) Application range
Multi-media filter is widely used in water treatment process. It is mainly used for pre-treatment of water treatment for turbidity, softening water, electrodialysis and reverse osmosis. It can also be used for sediment removal of surface water and groundwater.
(4) Product introduction
The multi-media filters produced by this product can be divided into manual type and fully automatic type according to the control type. The manual type mainly controls the operation of the filter, the positive washing and the back washing through the adjustment of the valve; and the fully automatic type controls the operation of the filter, the washing and the back washing by the FLECK controller, according to the tank body. The material can be divided into FRP tank, carbon steel tank and stainless steel tank. The inner wall of the tank can be coated with epoxy coating or rubber anti-corrosion according to user requirements.
