As we all know, activated carbon products have a wide range of applications, if the activated carbon used in pesticides, pharmaceuticals and other chemical industries is recycled and recycled, and then used in household water purifier filters, it is a very dangerous and irresponsible thing, and this behavior will bring harm. Activated carbon filter manufacturers teach you how to identify the method of regenerating and recovering activated carbon, and we must resolutely prevent such accidents from occurring.

First of all, we don't care about the level of the indicator. From the appearance alone, due to the activated carbon filter element manufacturers to recover the waste carbon raw materials, specifications are not exactly the same, may be mixed with coconut shell charcoal, apricot shell charcoal, walnut shell charcoal, peach shell charcoal, coal charcoal and other substances, the simple regeneration of the product particle size is uneven, the wall thickness of the particles will be significantly different, among which the wall thickness of apricot shell charcoal, walnut shell charcoal is thinner, although the wall thickness of peach shell charcoal is thick, but careful observation of the local surface will have pits on the surface of the peach shell, 20~40 mesh small granular carbon identification has a certain difficulty.

In general, the degree of variability of the particles is large. If you look at the surface chromaticity of the particles, the surface of the product regenerated at high temperature is gray and dark, and the cross-section of the particles is not bright, and there will be fine cracks when you look closely. If the edges and corners of the recycled carbon are not distinct from the appearance and shape, there is a slight smooth transition, mainly because the particles rub against each other during use, and the industrial water treatment filter tank will often be flushed and backflushed, and the particles will lose their sharp edges and corners due to mutual wear during the filtration process, which is particularly obvious. Some recycled carbon does not undergo high-temperature activation treatment, only for simple pickling, alkali washing, water washing, a small amount of particles in the treated recycled carbon surface is dark yellow, and some will have a small amount of quartz sand particles.
