The main function of activated carbon block filters is that it can absorb excess organic matter,some nitrogenous wastes and pigments in the water! In recent years, the Chinese Ministry of Health has begun to control COD in water when treating water filtration, because excessive organic matter will lower the Oxygen content of the water.
Many clients only know that activated carbon can treat sewage, circulating water, boiler water and purified drinking water, but they do not understand the specific working principle of activated carbon blocks. Today we will analyze the adsorption principle of activated carbon block and the reasons that affect the adsorption capacity of activated carbon filter.
The Adsorption Principle of The Activated Carbon Filter
The adsorption principle of the activated carbon filter is that the surface of the carbon block has a surface with a balanced density, which can adsorb organic substance impurities into the activated carbon particles. In the early stage of use, it has a strong adsorption effect. However, after a long period of time, the adsorption capacity of the activated carbon filter cartridge will be weakened to a certain extent, and the adsorption effect will also decrease. In turbid water with high levels of organic matter, activated carbon filters will quickly lose their filtration function. Therefore, the activated carbon cartridges should be cleaned or replaced regularly.
4 Reasons That Affect The Adsorption Capacity of Activated Carbon Block
1.The size of activated carbon particles
Generally speaking, the smaller the activated carbon particles, the larger the filtration area. Therefore, the powdered activated carbon has a large total area and good adsorption effect, but the powdered activated carbon is easily flowed into the water because it is not formed, and is rarely used in daily water filtration equipment. Sintered activated carbon blocks are not easy to flow due to particle formation, and impurities such as organic substances in water are not easily blocked in the activated carbon filter, and are easy to carry and replace.
2.The quality of the water
When in acidic water, the adsorption capacity of activated carbon rods for anionic substances is relatively weakened; when in alkaline water, the adsorption capacity of activated carbon rods for cationic substances is weakened.
3. The temperature of the water
The higher the water temperature, the stronger the adsorption capacity of the activated carbon block filter, and the better the effect of removing the pollutants in the water; if the water temperature is above 30 °C, the adsorption capacity of the activated carbon water filter core reaches the limit, and its performance may gradually decrease.
4. Time of contact with water.
The adsorption capacity of the activated carbon filter is proportional to the time of contact with water. The longer the contact time, the better the water quality after filtration.
