Anonymous users2024-02-07The adsorption principle of activated carbon is to form a balanced surface concentration on the surface of its particles. The size of the activated carbon particles also has an impact on the adsorption capacity.
In general, 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, but powdered activated carbon is easy to flow into the water tank with water, which is difficult to control and is rarely used. The granular activated carbon is not easy to flow due to the particle forming, and the impurities such as organic matter in the water are not easy to block in the activated carbon filter layer, and its adsorption capacity is strong, and it is easy to carry and replace.
The adsorption capacity of activated carbon is directly proportional to the time of contact with water, and the longer the contact time, the better the quality of the filtered water. Note: Filtered water should flow slowly out of the filter layer.
The new activated carbon should be washed before the first use, otherwise there will be inky black water flowing out. Before the activated carbon is loaded into the filter, a sponge with a thickness of 2 3 cm should be added at the bottom and top, the function is to prevent large particles of impurities such as algae from penetrating into it, and after the activated carbon is used for 2 3 months, if the filtration effect decreases, the new activated carbon should be replaced, and the sponge layer should be replaced regularly.

Anonymous users2024-02-06Activated carbon filter is a more commonly used water treatment equipment, as a water treatment desalination system pre-treatment can adsorb the residual chlorine that cannot be removed in the pre-filtration, can effectively ensure the service life of the post-stage equipment, improve the effluent quality, and prevent pollution, especially to prevent the free residual chlorine poisoning pollution of the post-stage reverse osmosis membrane and ion exchange resin.
Precautions for the use of activated carbon carbon filtration products.
1.The core part of the filter is the filter element of the filter, the filter element is mainly composed of the filter frame and the stainless steel wire mesh, the stainless steel wire is a wearing part, which needs to be specially protected, if the stainless steel wire is found to be deformed or damaged, it should be replaced immediately;
2.When the filter works for a period of time, a certain amount of impurities will accumulate inside the filter, then the pressure will increase, the flow rate will also decrease, and the impurities in the filter element need to be removed in time;
3.When cleaning impurities, special attention should be paid to the stainless steel wire mesh on the filter element should not be deformed or damaged, otherwise, the filter installed later, the purity of the filtered medium will still not meet the design requirements, and the compressor, pump, instrument and other equipment will be damaged.

Anonymous users2024-02-05Activated carbon is a very fine carbon particle.
There is a large surface area, and there are even finer pores in the carbon grains – capillaries. This capillary has a strong adsorption capacity and is in full contact with gases (impurities) due to the large surface area of the carbon particles. When these gases (impurities) touch the capillaries, they are adsorbed and purified.
The surface area of activated carbon is very important, and the specific surface area of activated carbon is only true and reliable if the results are detected by the BET method, and there are many instruments in China that can only do direct comparison detection. The specific surface area test at home and abroad adopts the multi-point bet method, and the specific surface area measurement standards formulated at home and abroad are based on the bet test method, please refer to China's national standard (GB T
19587-2004)-Method for determining the specific surface area of solid substances by the principle of gas adsorption. Specific surface area detection is actually more time-consuming work, due to the difference in sample adsorption capacity, the test of some samples may take a whole day, if the test process is not fully automated, then the tester can not leave at any time, and to be highly concentrated, observe the dashboard, control the knob, a little carelessness will lead to the failure of the test process, which will waste a lot of valuable time of the tester. f-sorb

Anonymous users2024-02-041. Composition structure
The activated carbon filter is mainly composed of the tank part and the supporting accessories part, and here we mainly introduce the internal structure of the tank part. According to the general filter structure design, the equipment is mainly composed of a pressure tank, a rubber lining or resin part, a water distributor, a partition, a filter cap, a viewing glass, a packing port, a discharge port, a water inlet, a water outlet and other parts.
Diagram of the internal structure of the activated carbon filter.
2. Working principle
After the raw water enters the activated carbon filter tank, through the water distributor at the top, the raw water fully enters the activated carbon filter layer, and after the filter material of the 1200mm filter layer, the impurities in the raw water such as suspended solids, particulate matter, flocculents, and gels are removed by adsorption filtration, and the water enters the bottom outlet space through the filter cap of the middle partition plate, and is output from the bottom nozzle, and the filtration step is completed since then. When the filter impurities inside the tank increase, manually open each valve or automatically open the activated carbon filter backwash step, so that the activated carbon filter material can restore the filtration activity and continue to filter the raw water.

Anonymous users2024-02-03In a water treatment system, a balanced surface concentration is formed on the surface of activated carbon particles. The size of activated carbon particles has a direct impact on its adsorption capacity. Under normal circumstances, the smaller the particle size of activated carbon, the larger its filtration area.
Therefore, the powdered form of activated carbon has the largest total area, and the adsorption effect is also the best, but the powdered activated carbon is easy to flow into the water tank with the water flow when used, and it is not easy to control, so this method is relatively rare. The granular activated carbon will not be easy to flow because the particles are formed, and the organic matter and other impurities in the water are not easy to block in the activated carbon filter layer, and its adsorption capacity is strong, and it is easy to carry and replace.
The adsorption capacity of activated carbon particles is directly proportional to the time of water contact, and the longer the contact time between activated carbon particles and water, the better the water quality after filtration. It is important to note that the water to be filtered should flow slowly out of the filter layer.
New activated carbon should be washed before first use, otherwise there will be inky black water coming out. Before the activated carbon particles are filled to the filter, a sponge with a thickness of 2 3 cm should be added at the bottom and top, the function is to prevent large particles such as algae from penetrating into it, and after the activated carbon is used for 2 3 months, if the filtration effect is reduced, the new activated carbon should be replaced, and the sponge layer should be replaced regularly.

Anonymous users2024-02-02The activated carbon filter uses granular activated carbon to further remove the residual residual chlorine, organic matter and suspended matter impurities in the effluent of the mechanical filter, so as to provide good conditions for subsequent reverse osmosis treatment.
When the water flows through the pores of the activated carbon, various suspended particles and organic matter are adsorbed in the pores of the activated carbon under the action of van der Waals force; At the same time, the chlorine (hypochlorous acid) adsorbed on the surface of the activated carbon undergoes a chemical reaction on the surface of the carbon and is reduced to chloride ions, so as to effectively remove the chlorine, ensure that the residual chlorine amount of the effluent is less than that, and meet the operating conditions of the RO membrane. Over time, the trapped matter in the pores and between the particles of the activated carbon gradually increases, causing the pressure difference between the front and back of the filter to increase until it fails. Under normal circumstances, according to the pressure difference between the front and back of the filter, the reverse water flow is used to backwash the filter material, so that most of the intercepts adsorbed in the pores of the activated carbon are stripped off and taken away by the water flow, and the adsorption function is restored. When the activated carbon reaches the saturated adsorption capacity and completely fails, the activated carbon should be regenerated or replaced to meet the engineering requirements.

Of course. However, the effect and time of repeated use are greatly reduced. Because the activated carbon adsorbs other substances, it is difficult to remove it by general methods, especially the substances like filtered edibles, such as water, which are more difficult to do, and the industrial use is easier to deal with, because the method of processing activated carbon must use substances such as acid and alkali, if it is not cleaned after treatment, it is better not to use it more safely. >>>More
