A tank filtering device, the outer shell is usually made of stainless steel or fiberglass, and the interior is filled with activated carbon, used to filter pollutants in the water. Free substances, microorganisms, some heavy metal ions, and can effectively reduce the color of water. The system uses a nutshell activated carbon filter. The activated carbon can not only adsorb electrolyte ions, but also perform ion exchange adsorption.
The adsorption principle of activated carbon is to form 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, powdered activated carbon has the largest total area and the best adsorption effect. However, powdered activated carbon can easily flow into the aquarium with water, making it difficult to control and rarely used. Granular activated carbon is not easy to flow due to the shape of the particles, and impurities such as organic matter in the 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 time it is in contact with water. The longer the contact time, the better the quality of the filtered water. Note that the filtered water should flow out of the filter layer slowly. New activated carbon should be washed clean before first use, otherwise ink black water will flow out. Before the activated carbon is installed into the filter, a ~cm thick sponge should be spread at the bottom and top to prevent algae and other large particle impurities from penetrating in. After using the activated carbon for ~ months, if the filtration effect decreases, new activated carbon should be replaced. The sponge layer should also be replaced regularly.
The activated carbon filter pressure vessel is a pressure vessel filled with a coarse quartz sand cushion and high-quality activated carbon.
A layer of balanced surface concentration is formed on the surface of activated carbon particles, and organic impurities are adsorbed into the activated carbon particles. The adsorption effect is very high in the early stage of use. However, over time, the adsorption capacity of activated carbon will weaken to varying degrees, and the adsorption effect will also decrease. If the water in the aquarium is turbid and contains high levels of organic matter, the activated carbon will quickly lose its filtering function. Therefore, activated carbon should be cleaned or replaced regularly.
