The difference between the front filter 20 cm and 40 microns There is a little difference between CM and Micron. generally Micron is the unit of filtering accuracy. what you said is that the filter is 20 cm long and the filtering accuracy is 40um.
Working Principle of filter The working principle of the filter is: when the filter works,The water to be filtered enters through the nozzle,Flow through the filter screen,And enter the pipe required by the user through the outlet used for the process cycle.The particulate impurities in the water are trapped by the filter.With this continuous cycle,More and more particles have been intercepted,The filtering speed is getting slower and slower.Imported sewage is still entering continuously,The filter holes will become smaller and smaller,Causes a differential pressure between the inlet and outlet.When the difference reaches the set value,The differential pressure transmitter sends an electrical signal to the controller.The control system starts the drive motor,The drive shaft rotates through the transmission parts,At the same time, the sewage outlet is opened and discharged from the sewage outlet.When the filter is cleaned,The differential pressure drops to the minimum,And the system returns to the in
Ask you about the deep treatment process of prawn and domestic sewage treatment plant: which is used for ordinary fast filter and continuous sand filtration? Advantages and disadvantages of two processes and economy 10 Ordinary fast filter and continuous sand filtration are two mature processes that are widely used at present,Difficult to distinguish,All have their own advantages and disadvantages.Economy,Easier to manage.Single,Water quality is different from standard.Sewage treatment is relatively thorough,Water quality can meet national standards.The investment is relatively large,Management is cumbersome.If it's just a general domestic sewage treatment,It is recommended to use ordinary fast filter.If there is industrial sewage,Or use continuous sand filtration.Application Scope of active sand filter I. continuous sand flow filter: Based on countercurrent principleIt is a continuous filtration equipment integrating coagulation, clarification and filtration,It is widely used in the fields of drink
