Activated carbon filter working principle (the role of activated carbon filter)
Activated carbon is widely used in our life, and its good adsorption ability is very popular. Activated carbon filter is a kind of tank filtration apparatus, the outside is generally fiberglass material, the inside is filled with activated carbon, which can filter the microorganisms in the water and part of the heavy metal ions, and can reduce the color of the water. So what is the working principle of this activated carbon filter? The principle of adsorption of activated carbon is that a layer of balanced surface concentration is formed on the surface of its particles. The size of the activated carbon particles also has an effect on the adsorption capacity. Generally speaking, the smaller the activated carbon particles, the larger the filtration area. Therefore, the total area of powdered activated carbon is the largest, and the adsorption effect is the best, but powdered activated carbon is easy to flow into the tank with the water, which is difficult to control and rarely used. Granular activated carbon due to particle molding is not easy to flow, organic matter in the water and other impurities in the activated carbon filter layer is not easy to block, its adsorption capacity is strong, easy to carry and replace.
