Activated carbon in the water pretreatment system, the activated carbon filter can adsorb the residual chlorine that cannot be removed in the previous stage to prevent the subsequent reverse osmosis membrane from being oxidatively degraded, and also adsorb the polluting substances such as small molecule organics leaked from the previous stage. It has obvious adsorption and removal effect on odors, colloids, pigments and heavy metal ions in water, and it also has the effect of reducing COD.
The principle of adsorption of activated carbon is: a layer of balanced surface concentration is formed on the surface of the particles, and then the organic substance impurities are adsorbed into the activated carbon particles, and the initial adsorption effect is very high. But over time, the adsorption capacity of activated carbon will be weakened to varying degrees, and the adsorption effect will also decrease. If the water in the aquarium is turbid and the organic content in the water is high, the activated carbon will soon lose its filtering function. Therefore, the activated carbon should be cleaned or replaced regularly.
The size of the activated carbon particles also affects the adsorption capacity. In general, the smaller the activated carbon particles, the larger the filtration area. Therefore, the total area of powdered activated carbon is large and the adsorption effect is good, but the powdered activated carbon easily flows into the aquarium with water, which is difficult to control and is rarely used. Granular activated carbon is not easy to flow due to the formation of particles. Impurities such as organic matter in water are not easy to block in the activated carbon filter layer. It has strong adsorption capacity and is easy to carry and replace.
The adsorption capacity of activated carbon is directly proportional to the contact time with water. The longer the contact time, the better the filtered water quality. Note: The filtered water should flow out of the filter layer slowly. New activated carbon should be washed and cleaned before the first use, otherwise black ink will flow out. Before the activated carbon is installed in the filter, a 2 to 3 cm thick sponge should be added to the bottom and top to prevent large particles such as algae from penetrating into it. After using the activated carbon for 2 to 3 months, if the filtering effect decreases, it should be replaced. The new activated carbon and sponge layer should be replaced regularly.
Activated carbon filter pressure vessel is a pressure vessel filled with coarse quartz sand cushion and high-quality activated carbon.
