              Multimedia filter is a kind of filter device that uses one or several kinds of filter media to remove suspended impurities and clarify water through granular or non-granular materials with a certain thickness under a certain pressure. The commonly used filter materials are quartz sand, anthracite, manganese sand and so on.
              Multimedia filter system sets up a dosing system, the dosing agent is polyferric sulfate. Polyferric sulfate has remarkable effects on turbidity removal, decolorization, deoiling, dehydration, sterilization, deodorization, algae removal, COD, BOD and heavy metal ions removal, etc. The dosing point is set on the jellyfish tube of multi-media filter to set up a pipeline mixer for lifting. High effect.
              In view of the existing problems in operation, Zibo Multimedia Filter Company recommends the following measures:
              Upgrade the original system. The operation of the desulfurization wastewater treatment system should be checked for the turbidity of the water coming from the desulfurization wastewater, and the operation of the desulfurization wastewater treatment system should be adjusted and revamped accordingly. In the range of design parameters, the backwashing flow rate of Zeda multi-medium filter should be increased, so as to avoid the residual sediment in the filter layer and prevent the sediment and filter material. Caking into lumps. At the same time, consider increasing air washing to ensure the effect of backwashing; re-screen the filter material to optimize the particle size distribution; control the flow rate and pressure during operation; do not drain the water in the filter during non-operation, and retain a certain height of water cushion. Through a series of adjustment of operation mode, we found a relatively ideal operation mode, the water quality improved, and reached the standard of reused water quality.
              In the design of multi-media filter, the unattended operation mode can be directly considered. It is generally put into operation and backwashed, which is convenient for operators to operate. In wastewater treatment of power plants, multi-media filters can pretreat wastewater, realize the reuse of water resources, and also bring economic benefits.
