Activated carbon filter element is a filtering medium mainly used for air purification and water purification. The main function of activated carbon filter is to adsorb organic matter and fine dust particles in air and water, and filter out these substances. Activated carbon filter generally consists of several layers: the bottom layer is a sponge like porous carbon layer, the middle layer is a non-woven filter layer, and the upper layer is a fibrous porous filter layer.

It mainly relies on internal pores to form a network structure when adsorbing substances such as organic matter and fine dust particles. It is generally made of materials with large surface area, high porosity, high strength, and complex structure. Activated carbon filter has the advantages of uniform pore size distribution, large porosity, small pore size, large specific surface area, and strong adsorption performance. It is widely used in the fields of air purification and water treatment.

background

The hygiene standards for drinking water in China were promulgated and implemented in 1989, and have not been modified for many years. As of May 2019, 12 provinces (autonomous regions, municipalities directly under the central government) have revised the hygiene standards, mainly adding indicators such as removal of color and odor, disinfection by-products, residual chlorine, and chloramine, to provide safer and higher quality drinking water for the public. Activated carbon is a commonly used water purification material. Due to its high adsorption capacity, it can effectively remove suspended solids (such as sediment, rust, etc.) and organic matter (such as bacteria) from water. In addition to the aforementioned pollutants, the activated carbon filter can also remove some toxic and harmful gases from water; Some difficult to degrade organic and inorganic substances, as well as some heavy metal ions; At the same time, it can also kill some bacteria.

Performance characteristics

1. The activated carbon filter has strong adsorption capacity, long service life, and large flow rate.

2. Activated carbon filter is a new and efficient industrial deodorant with strong adsorption ability, which can be used for the adsorption of harmful gases such as formaldehyde, ammonia, benzene, and can remove various odors, such as rotten egg odor and fishy odor.

3. The activated carbon filter element does not contain any chemical additives, has no secondary pollution, and can be reused.

operational principle

When water flows through the activated carbon filter, impurities, bacteria, viruses, etc. in the water are adsorbed on the surface of the activated carbon filter, and the odors and harmful substances in the water are decomposed into substances that are harmless to the human body.

When water flows through the activated carbon filter, as the water flow continues, the impurities and harmful substances adsorbed in the activated carbon filter slowly flow away under the action of the water flow, while the remaining water is reused.
