How is the test process of the filter bag dynamic filter performance tester carried out? About the relevant process of the test,1.Initialization treatment: Determination of filter dust performance of initial filter material samples,When the pressure loss reaches 1000,After repeated 30 times, the weight gain of the high-efficiency filter membrane and the dust concentration at the outlet were determined and recorded;2.Aging Treatment: Aging Treatment at 10000 intervals 5S;3.Stabilization treatment: stabilization treatment,Installation process A 10 times filter dust-Cleaning operation;4.Stabilization treatment: 30 dust filtration according to-Ash cleaning operation.It can be used to test the filtration performance of filter material.The device itself is easy to operate,Compact and sturdy design.The filter test dust concentration value can be adjusted quickly and conveniently,The actual use of simulation is high,Simulate a variety of actual conditions.

Is the pre-filter filtering accuracy 90um good or 4um good? It's not that the higher the filtering accuracy, the better. it depends on what kind of requirements you are suitable. It is best to make it clear by yourself. don't choose casually. The smaller the number, the better, indicating that the higher the filtering accuracy, the more dense the filter screen. I would like to ask what equipment is specifically used for. generally, 40um is commonly used.

Development status and advantages and disadvantages of membrane filtration technology, mainly used for sewage treatment The current membrane technology is generally used for fermentation liquid filtration, oil-water separation, seawater dilution, etc,.The reason is that the cost is too high.And not suitable.The film can only be used for filtration,But many sewage is heavy metal or nitrogen exceeding the standard,Too small,Ordinary membrane can't purify,Reverse osmosis membrane can,But the cost is too high and too high,Who can't afford it.You can think of a ton of water, dozens or even hundreds of pieces of waste,Who used it?There is one technology for membrane technology to treat sewage,It's called trunk,But not filtering,Instead, Catalyst is added to the membrane to catalytic degradation of harmful substances in water and so on.Therefore, filtering technology cannot be counted.And liquor is not a very mature technology,It is usually used to treat organic wastewater,There is nothing to do with inorganic wa
