What are the conditions for installation and operation of multi-media filter?

Want the stability of multi-media filter operation, there are many factors are very important, quality is a very important point, of course, and installation work for the normal use of multi-media filter also has a great impact, this is also a very important point, some conditions in the installation process to be guaranteed, so what are the conditions of the installation and operation of the media filter?

1. in the filling of the filter material, carefully check the tightness of the filter cap, to ensure that all the filter cap are tight, can be filled with filter material.

2. in the construction of the concrete foundation, according to the filter foot hole position reserved holes, and in the foundation to reach the design of the light can be carried out after the multi-media filter hoisting and nozzle assembly work.

3. In the early stage of use, the local water quality is studied to determine the types of pollutants in the water, and then the varieties of coagulants that need to be added without rating and the amount of dosage, and the opening degree of drainage gate valve when backwashing.

4. in the use of multi-media filter, we should pay attention to the turbidity of the water can not be higher than the standard specified in the design, and in strict accordance with the requirements of the design to carry out the backwash work, otherwise it will cause the shortening of the operation cycle, but also lead to the formation of mud balls in the filter layer, serious will also affect the quality of the water.

5. in the direct filter, the coagulant configuration into the corresponding concentration, before the pump to add.

6. When multiple sets of multi-medium filters are used in parallel, the inlet and outlet pipes should be equipped with gate valves.

The above is the installation and operation of the multi-media filter all content, I hope to help you, the structure of the multi-media filter is simple, convenient operation, in many aspects have a good application.
