Powdered activated carbon is a kind of high-quality sawdust, coconut shell, coal and other raw materials after finishing processing made of activated carbon powder,so divided into wood powder activated carbon and coal powder activated carbon. Powdered activated carbon is a common type of activated carbon, usually composed of many small carbon particles. It has a high specific surface area and porosity, can absorb harmful substances in water. Powdered activated carbon is usually used in water treatment, gas treatment, metal extraction and other processes to remove suspended matter, organic matter, chlorine and other harmful substances. Because of its high adsorption performance, powdered activated carbon is widely used in water treatment, especially in the field of hard water and sewage treatment.
Powdered activated carbon is a common adsorbent, with the following characteristics:
Widely used: powdered activated carbon in a variety of fields have a wide range of applications, such as gas adsorption, water treatment, sewage treatment, sugar industry, pharmaceutical industry.
High Efficiency: powdered activated carbon has a high specific surface area and pore structure, can improve the adsorption efficiency, to achieve rapid adsorption and separation of pollutants.
Environmental Protection: because the powdered activated carbon can be regenerated, it can avoid the waste of resources and environmental pollution caused by one-time use.
Gas adsorption: activated carbon powder can be used for a variety of gas adsorption, such as oxygen, nitrogen, carbon dioxide and so on. In industrial production, activated carbon powder is widely used in air purification, wastewater treatment, gas separation and other fields.
Water treatment: activated carbon powder has a high specific surface area and pore structure, can be used in water treatment to remove organic matter, chlorine and other harmful substances, in order to achieve the goal of water purification. In addition, activated carbon powder can also be used in wastewater treatment, ion exchange and other water treatment processes.
The following factors should be considered when selecting powdered activated carbon:
Appearance: powdered activated carbon presents a gray, brown or black powder.
Specific surface area: the larger the specific surface area, the stronger the adsorption capacity. Therefore, it is necessary to select powdered activated carbon with high specific surface area.
Porosity: the larger the porosity, the stronger the adsorption capacity. Therefore, it is necessary to select powdered activated carbon with high porosity.
Chemical stability: in some cases, need to use a high chemical stability
The use of powdered activated carbon can be adjusted according to specific application scenarios and needs. Here are some common ways to use it:
Gas Treatment: the right amount of powdered activated carbon into the gas, through adsorption, filtration and other means to remove harmful gases, to purify the gas.
Waste water treatment: the right amount of powdered activated carbon into the waste water, can be used to remove organic matter, chlorine and other harmful substances, to purify water.
Water treatment: the right amount of powdered activated carbon added to tap water, can be used to remove the water odor, residual chlorine and other harmful substances, in order to achieve purification of water quality.
The following factors should be considered when choosing the suitable particle size powdered activated carbon:
The particle size of powdered activated carbon also affects its adsorption performance and application effect. Generally speaking, it is necessary to select powdered activated carbon with suitable particle size in order to achieve the best adsorption effect.
Application scenario: different application scenarios require different particle sizes of powdered activated carbon. For example, water treatment and gas treatment require powdered activated carbon with smaller particle sizes, while metal extraction requires powdered activated carbon with larger particle sizes.
Raw water quality: the raw water quality of different powder activated carbon particle size will have an impact. For example, if the raw water contains a large amount of suspended solids and organic matter, a smaller particle size of powdered activated carbon should be selected; if the raw water contains more chloride ions and other anions, it is necessary to select a larger particle size of powdered activated carbon.
Waterworks status: the type and amount of water purifier used in waterworks also affects the particle size of powdered activated carbon required. For example, powdered activated carbon with higher porosity may be selected if the waterworks use advanced oxidizers, or smaller porosity if the waterworks use precipitating agents
In water treatment, it is necessary to choose the smaller particle size powdered activated carbon because the smaller particle size powdered activated carbon has the following advantages:
Faster adsorption rate: the adsorption rate of powdered activated carbon is related to its particle size. Smaller particle size means larger specific surface area and more pores, so powdered activated carbon can absorb harmful substances in water more quickly.
Stronger adsorption capacity: with the same specific surface area, the smaller particle size has larger porosity and more surface energy, so it can provide more adsorption sites and improve adsorption capacity.
Better Chemical Stability: harmful substances in water treatment are usually chemically active organisms and microorganisms that react easily with metal ions. Smaller particle sizes can reduce the surface area of particles in contact with these harmful substances, thereby improving their chemical stability.
The activated carbon powder can be regenerated by gasification, pyrolysis and other ways to achieve sustainable use.
Pyrolysis regeneration: the saturated powdered activated carbon heated to high temperature, so that the adsorption material desorption, and then use cooling gas cooling, can be reused.
Water vapor regeneration: saturated powdered activated carbon exposed to high temperature and high humidity environment, the use of water vapor will be adsorbed substances, and then use dry gas cooling, can be reused.
Packaging form: in the choice of powdered activated carbon, but also need to consider its packaging form. Commonly used packaging forms including cartons, plastic bags, pallets, etc. , need to be selected according to actual needs. In conclusion, the above factors should be taken into account when choosing powdered activated carbon to ensure that it has high adsorption performance and application effect, and has economic and practical characteristics.
