The role of multi-media filters Remove impurities such as mud sand, suspended matter, colloid and algae from the water,Reduce mechanical damage and pollution to reverse osmosis membrane elements.A multi-media filter uses one or more filter media,At a certain pressure, water with high turbidity is passed through granular or non-granular materials of a certain thickness,So that the process of effectively removing suspended impurities to clarify water,The commonly used filter material has quartz sand,Anthracite,Manganese sand, etc,It is mainly used for removing turbidity from water treatment,Softened Water,Pre-treatment of pure water, etc,The turbidity of the effluent can reach less than 3 degrees.Multi-media filter (filter bed ),Both two or more media are used as the media filter of the filter layer,In the industrial circulating water treatment system,It is used to remove impurities and absorb oil from sewage,Make the water quality meet the requirements of recycling.The role of filtering,It is mainly

What are the principles and functions of the filter? When the filter works,The water to be filtered enters by the water outlet,Flow through the filter,Through the export to enter the pipeline required by the user to carry out the process cycle,The particulate impurities in the water are trapped inside the filter.Such a constant cycle,More and more particles have been trapped,The filtering speed is getting slower and slower,The imported sewage is still entering continuously,The filter holes will be smaller and smaller,Thus, there is a pressure difference between entering and exporting,When the tolerance difference reaches the set value,The differential pressure transmitter transmits the electrical signal to the controller,The control system starts the drive motor to drive the shaft rotation through the transmission assembly,At the same time open sewage outlet,Discharged from the sewage outlet,When the filter is cleaned,The pressure drop to the minimum,The system returns to the initial filter,The syst
