Activated Carbon In Water Purification

Activated Carbon In Water Purification

Do you all know the water you can drink? Water is a substance that coffee needs, and clean water is an indispensable thing in people's lives. No matter how high quality water is, we can get the highest quality water. It is a combination of various technologies. The improvement of living standards determines consumers' better choices for tasting colorless and peculiar smells. More and more industrial processes also require cleaner water quality.

Some bats in the water are a serious hazard to human health and animals, concerning the quality of urban production. Microtoxins, disinfection by-products, drug residues, waste batteries and substances combined in raw water can even affect fertility. There are more and more requirements for improving water quality, and proactive solutions are needed. Only with our high-level technical manufacturing capabilities can we achieve improved water purification functions.

The biological activity of rainwater runoff, groundwater seepage or surface water source water is enhanced. As the amount of natural organic matter rises, in several areas of reservoirs and river raw water supply, there has been a large number of algae degradation, resulting in earthy mildew taste and other odor problems. This time is when our activated carbon leaves the factory. The activated carbon has a strong adsorption capacity and can effectively adsorb organic matter, pollutants, impurities, and unwanted gases in the water.

The effect of activated carbon

The process of activated carbon water filter adsorbing impurities in water is appropriately complicated, including the combined effects of ion attraction, molecular effect force (van der Waals force), and chemical impurities. The difference in the process of activated carbon will also cause its adsorption capacity to be different. The activated carbon adsorption method uses the porous properties of activated carbon to make one or more impurities in water adsorbed on the surface of the activated carbon and removed. Such as removing organic matter, colloidal particles, microorganisms, residual chlorine, smell, etc. in the water. Adsorption is composed of two rate methods: rapid dispersion and slow dispersion. Rapid dispersion can exert an adsorption capacity exceeding 60% to 80% within a few hours. It is the dispersion of solute molecules along the macropores with lower resistance in the carbon molecular structure. When the solute molecules enter the pores connected to the large pores, they receive a lot of resistance due to their small pore size, and then cause slow dispersion. The adsorption capacity of activated carbon is not only related to the specific surface area, but also inseparable from the pore structure of the pores.Macropores provide a way for solute molecules to disperse, make them enter the pores and then reach the intention of adsorption, so the adsorption force of solute molecules is mainly affected by macropores. The organic matter contained in the water contains not only small molecules, but also a wide range of macromolecules. The area occupied by pores exceeds 95% of the surface area, and the amount of adsorption depends on the pores. Therefore, in the process of sewage treatment, it is necessary to select suitable activated carbon to meet the different needs of different adsorbents. The adsorption of solute molecules is mainly the molecular effect force, that is, the van der Waals force plays a key role. Different activated carbon has different pore diameters and different distribution areas, so activated carbons of different types have different adsorption capabilities for different solute molecules. Physical adsorption is related to such factors as the affinity of activated carbon for solutes, the solubility of solutes, the size of solute molecules, the dispersion of activated carbon's pores, and the surface area.

Activated carbon for water treatment
1, activated carbon sewage purification

 There are several types of adsorption methods for activated carbon, which are fixed bed, touch adsorption, moving bed and moving bed methods. In the meantime, there is only one adsorption method for powdered activated carbon, which is also its characteristic location. Powdered activated carbon is in the process of doubts about sewage treatment. According to the different conditions of water quality, increase the metering and input. There are projects with large changes in sewage quality. Particularly good results. At the same time, powder activated carbon can also be used for dry or wet cast according to different needs. Wet cast can deal with some usual sewage questions, and dry cast can be used for sewage emergency treatment. At the same time, it is also necessary to determine the type of powdered activated carbon based on the difference in the quality of the raw water, especially the molecular mass of the organic matter in the water. In the emergency treatment of sewage, activated carbon can be injected into the raw water in front of the sedimentation tank, so that it can be fully touched and adsorbed. After the adsorption is full, it can be removed by the method of deposition. Powdered activated carbon is widely used in urban sewage treatment in Europe, the United States and other countries. In the early 1980s, the United States used about 2.6×105t of powdered activated carbon in sewage treatment every year, and it has a trend of increasing year by year.

2.Biological activated carbon

Activated carbon plays an insignificant effect in sewage treatment due to its excellent adsorption ability. Its common molecular structure and specific table activity, strong acid and alkali resistance, high temperature and high pressure resistance and other general functions have attracted everyone’s attention. The position is rising day by day. However, activated carbon also has a series of questions about easy absorption and high regeneration cost. In order to effectively deal with this question, everyone combined the principle of biodegradable waste with the principle of activated carbon adsorption, and invented the biological activated carbon purification technology.

 Bio-activated carbon purification technology includes two effects of biodegradation and activated carbon adsorption, which not only increases the fullness of activated carbon, but also strengthens its adsorption function, so it has attracted attention. Now many countries in the world have adopted this new skill.
