A filter called activated carbon filter is often used in water treatment. This filter device is also the earliest filter device used in large-scale water treatment. This filter device can be used to filter water very efficiently and economically to treat water. Some friends may not understand why this activated carbon can treat water? So let me introduce to you the principle behind it.
In fact, the principle of activated carbon filter operation is very simple. Everyone should be familiar with activated carbon. However, there are many holes on the surface. After the activated carbon is placed in the water, the holes on the surface will form a local Concentration equilibrium state, but if the amount of impurities in the water is relatively large, it will break the equilibrium state of this concentration, so these impurities will be adsorbed into these holes, thus achieving the effect of adsorbing impurities in the water, thus It also achieves the effect of water treatment and water purification. Especially some water contains a lot of organic matter or some water is turbid, such as mountain spring water or water in some rivers and lakes will contain more impurities, so these waters are very suitable for using activated carbon for cleaning. and processing. There are many pores on the surface of activated carbon. After these pores absorb enough impurities, the adsorption capacity of activated carbon will decrease, so it is necessary to replace the activated carbon at this time to ensure that the water can be filtered continuously for a long time.
Activated carbon filter is the general principle of use, so I will simply share it with you here. Since the cost of activated carbon itself is very cheap, the overall use cost of this water filter is not high. In the process of large-scale water treatment, activated carbon can be produced in batches, and then in the process of water treatment, These filters are replaced in regular batches so that higher water filtration treatment results can be achieved at a lower cost. The general filter can be replaced with a new filter when it is used continuously for about three months to half a year. Of course, different filter sizes have different adsorption capacities and service life, so the frequency of replacement of different filters is different when actually filtering and purifying water resources.
