4、 Product Description:

Activated carbon filter is also called carbon filter. Activated carbon is a kind of very small carbon particle with a large micropore per unit area. Usually we call it capillary pore. This kind of capillary has a strong adsorption capacity. Due to the large surface area of carbon particles, it is in full contact with impurities in water. These impurities can be adsorbed in micropores to remove colloids and other impurities in water. Activated carbon can also adsorb Cl ions and ozone in water, and has certain adsorption capacity for organic matters in water. It can obviously adsorb pigments in water. In water treatment industry, we generally require that the iodine value is above 700mg, so the adsorption capacity of activated carbon is strong. The work of activated carbon filter is completed by carbon bed. The activated carbon particles which make up the carbon bed have many micropores and huge specific surface area, and have strong physical adsorption capacity. Water passes through the carbon bed, and organic pollutants in the water are effectively adsorbed by activated carbon. In addition, there are some oxygen-containing tube energy groups on the non crystalline part of the surface of the activated carbon, so that the organic pollutants in the water passing through the carbon bed are effectively adsorbed by the activated carbon. Activated carbon filter is a kind of commonly used water treatment equipment. As the pre-treatment of water treatment desalination system, it can effectively guarantee the service life of the later stage equipment, improve the water quality of the effluent, prevent pollution, especially prevent the free residual oxygen poisoning pollution of the later stage reverse osmosis membrane, ion exchange resin, etc.. 　

gd55光大彩票5、 Equipment principle:

1. Working principle:

gd55光大彩票◇ The adsorption principle of activated carbon is to form a layer of equilibrium surface concentration on its particle surface. The size of 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 powder like activated carbon has the largest total area and the best adsorption effect, but the powder like activated carbon is easy to flow into the water tank with water, difficult to control and rarely used. Granular activated carbon is not easy to flow due to particle forming, and impurities such as organic matters in water are not easy to block in the filter layer of activated carbon, which 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 is, the better the filtered water quality will be. Note: the filtered water should flow out of the filter layer slowly. The new activated carbon should be washed clean before the first use, otherwise there is ink black water flowing out. Before the activated carbon is put into the filter, 2-3cm thick sponge shall be laid at the bottom and top to prevent the algae and other large particle impurities from penetrating. After the activated carbon is used for 2-3 months, if the filtering effect decreases, the activated carbon shall be replaced with a new one, and the sponge layer shall 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. A layer of equilibrium surface concentration is formed on the surface of activated carbon particles, and then organic impurities are adsorbed into the activated carbon particles. The adsorption effect is very high at the initial stage of use. However, as time goes on, the adsorption capacity of activated carbon will be weakened to some extent, and the adsorption effect will also decline. If the water quality in the aquarium is turbid and the organic matter content in the water is high, the activated carbon will lose its filtration function soon. Therefore, the activated carbon should be cleaned or replaced regularly.

2. Adsorption principle:

◇ Activated carbon is a kind of very small carbon particle with a large surface area, and there are even smaller pores in the carbon particle capillary. This kind of capillary has a strong adsorption capacity. Due to the large surface area of carbon particles, it can fully contact with gas (impurities). When these gases (impurities) are adsorbed on the capillary, they play a role of purification. The research on the surface area of activated carbon is very important. The specific surface area data of activated carbon is only true and reliable if it is detected by BET method. There are many instruments in China that can only do the direct comparison method. The multi-point BET method is adopted for the specific surface area test at home and abroad. The standards for the determination of the specific surface area developed at home and abroad are based on the bet test method. Please refer to the national standard of China (GB / T 19587-2004) - the method for the determination of the specific surface area of solid substances based on the principle of gas adsorption bet. The specific surface area test is actually a time-consuming work. Due to the different adsorption capacity of samples, the test of some samples may take a whole day. If the test process is not fully automated, the tester can not leave at any time, and should focus on the instrument panel, control knob, a little inattention will lead to the failure of the test process, This wastes a lot of valuable time for testers. The F-Sorb 2400 specific surface area tester is an instrument that can truly realize the detection function of BET method (with direct comparison method), more important F-Sorb 2400 specific surface area tester is the only fully automatic and intelligent specific surface area testing equipment in China so far. Its test results are highly consistent with the international ones, and its stability is also very good. At the same time, it reduces human error and improves the accuracy of test results.
