What Are The Characteristics Of Activated Carbon Filter

What are the characteristics of activated carbon filter
The way activated carbon adsorbs is by forming a layer of balanced surface concentration on the surface of its particles. The size of activated carbon particles also affects the adsorption capacity. Generally speaking, the smaller the activated carbon particles, the larger the filtration area. Therefore, the total area of powdered activated carbon field, adsorption effect field is good, but powdered activated carbon is easy to flow into the water tank, difficult to control, rarely used. Granular activated carbon because of particle forming is not easy to flow, organic matter and other impurities in the water in the activated carbon filter layer is not easy to block, its adsorption capacity is strong, easy to carry and replace.
Form a layer of balanced surface concentration on the surface of activated carbon particles, and then the organic matter impurities adsorbed to activated carbon particles, the adsorption effect is very high at the beginning of the use. But for a long time, the adsorption capacity of activated carbon will be weakened to varying degrees, and the adsorption effect will also decline. If the water quality in the aquarium is cloudy, the content of organic matter in the water is high, activated carbon will soon lose the filtration function. Therefore, activated carbon should be cleaned or replaced regularly.
The adsorption capacity of activated carbon is directly proportional to the contact time with water, the longer the contact time, the better the water quality after filtration. Note: The filtered water should flow slowly out of the filter layer. The new activated carbon should be washed clean before the first use, otherwise there is ink black water flow out. Activated carbon in the filter before loading, should be at the bottom and the top of the 2 ~ 3 cm thick sponge, the effect is to prevent algae and other large particles of impurities infiltrate into the activated carbon, the use of 2 ~ 3 months, if the filter effect decreases should be replaced with new activated carbon, sponge layer should be replaced regularly.
Activated carbon filter pressure vessel is a kind of pressure vessel filled with coarse quartz sand cushion and high quality activated carbon.
