Now, air pollution is very serious, and it has become difficult to breathe clean air. In order to improve air quality, various air filters have been produced. Among them, bag-type activated carbon air filters are A very popular one. Many people do not know about bag-type activated carbon air filters. Today, Xiaobian will introduce some knowledge about bag-type activated carbon air filters.

 

In the water quality pretreatment system, the bag-type activated carbon air filter can absorb the residual chlorine that cannot be removed in the pre-filtration to prevent the reverse osmosis membrane of the latter stage from being oxidatively degraded. Polluting substances such as small molecular organics have obvious adsorption and removal effects on odors, colloids, pigments, and heavy metal ions in water, and also have the effect of reducing COD. The SDI value of RO influent can be further reduced to ensure SDI<5 and TOC<2.0ppm.

 

The bag-type activated carbon air filter uses granular activated carbon to further remove residual chlorine, organic matter, and suspended impurities in the effluent of the mechanical filter, providing good conditions for subsequent reverse osmosis treatment. The bag-type activated carbon air filter mainly uses the activated carbon organic flocs with high carbon content, large molecular weight and large specific surface area to physically adsorb impurities in the water to meet the water quality requirements. When the water flows through the pores of the activated carbon, various suspended particles, organic matter, etc. Under the action of van der Waals force, it is adsorbed in the pores of the activated carbon; 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, thereby effectively removing the chlorine and ensuring the residual chlorine in the effluent. The amount is less than 0.1ppm, which meets the operating conditions of the RO membrane. With the passage of time, the retentate in the pores of the activated carbon and between the particles gradually increases, so that the pressure difference between the front and rear of the filter increases until it fails.

 

The bag-type activated carbon air filter pressure vessel is a pressure vessel filled with activated carbon. The work of the bag-type activated carbon air filter is done through a carbon bed. According to the manufacturer of Activated Carbon Pocket Air Filter, the activated carbon particles that make up the carbon bed have a lot of micropores and a huge specific surface area, and have strong physical adsorption capacity. The water passes through the carbon bed, and the organic pollutants in the water are effectively adsorbed by the activated carbon. In addition, there are some oxygen-containing functional groups on the amorphous 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. The bag-type activated carbon air filter is a commonly used water treatment equipment. As a pretreatment of the water treatment desalination system, it can effectively ensure the service life of the subsequent equipment, improve the quality of the effluent, and prevent pollution, especially to prevent the reverse osmosis membrane and ion exchange of the latter stage. Resin and other free state residual oxygen poisoning pollution.

 

Although people’s living standards have improved now, various pollution problems have caused a lot of headaches for many people. In order to solve the pollution problem, various filters have appeared in our lives. Type activated carbon air filter has a very wide range of applications, can help us improve the quality of the environment, is very beneficial to health.
