What are the differences between the quartz sand filter and activated carbon filter
quartz sand filter and activated carbon filter appearance look the same, is a manhole, in and out of the gate, the discharging mouth, leg, and its external pipeline operation is the same. Feeling that gives a person is a thing, if there is no nameplate, I'm afraid I don't know what kind of filter. So, quartz sand filter can replace activated carbon filter, in turn, activated carbon filter can replace quartz sand filter. The answer is certainly, no good. To answer this question from the quartz sand filter material and activated carbon filter material removal of impurities of mechanism. Within the
quartz sand filter, filled with quartz sand, particle is in commonly 0. 5 - 1. 1 - 2毫米 3 - 2毫米 4 mm, his action principle, mainly by filling of fine quartz sand compacted by intercepting intercept role to the particulate impurities in water of water soluble organic matter, the impurities such as ion effect is very small. He mainly intercept solid particles does not dissolve in water. Why must use quartz sand, ordinary sand? This is because the quartz sand high hardness, strong. Run or backwashing, are wash not easily broken. Think about it, if it is using ordinary quartz sand, run very has produced particles extruded and a broken body, as the water enters the trail process, they polluted the water. Moreover, backwashing and is due to the effect of friction, quartz sand is easily broken, so broken quartz sand by backwashing water drop, so that the filter before long, the packing is much less. So, be sure to quartz sand for water treatment. Not take it for granted said river sand line not line, we river sand a lot over there. It is ok to pack. The sand is not good.
activated carbon filter, internal filling, activated carbon filter, mainly through a huge amount of microporous activated carbon, the microporous has a strong adsorption, can adsorption of organic matter in water, colloid, impurities, such as ion adsorption, its action principle is the principle of quartz sand filter function is intercept intercept, so this is the most essential difference between activated carbon filter and quartz sand filter, activated carbon filter material has good and bad, LiangSanQianYiDun also has on the market, tens of thousands of also have a ton of activated carbon, is the essential difference between the first, the activated carbon iodine value, iodine value is related to the adsorption capacity of water, iodine value, the greater the adsorption capacity. Second, activated carbon filter material strength, poor activated carbon intensity is low, activated carbon is easily broken, so a lot of hours after activated carbon filter backwashing water are black.
