6x12 Coconut Shell Granular Jacobi Actonivated Carbon
Activated carbon, is a specially treated carbon that heats organic raw materials (rice husks, coal, wood, etc.) in the absence of air to reduce non-carbon components (this process is called carbonization), and then reacting with the gas, the surface is corroded to produce a microporous structure (this process is called activation).
Because the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, resulting in numerous small pores on the surface of activated carbon. The diameter of micropores on the surface of activated carbon is mostly between 2-50nm. Even a small amount of activated carbon has a huge surface area. The surface area per gram of activated carbon is 500-1500m2. Almost all applications of activated carbon are based on this characteristic of activated carbon.

Application in the water treatment areas :
1. Tips for using granular activated carbon for water treatment in waterworks
Waterworks that use surface water as their water source generally have a 1.5 meter deep granular activated carbon filter material tank, with a designed filtration rate of 9.5m/h. Activated carbon filter is used for the advanced treatment process of tap water, which can effectively remove chromaticity, odor, odor, and organic pollutants in tap water, thereby improving the water quality of tap water. Due to the limited adsorption capacity of granular activated carbon, the activated carbon will reach a saturation state after a certain period of adsorption use.
Therefore, it is necessary to regularly rinse the raw water quality during use. Generally, it is rinsed once every six days, and the backwash strength needs to reach a filter expansion rate of over 30%. After repeating this process for a period of time, the formation of a biofilm on the surface of the carbon is dominated by biodegradation.
2. Application of Activated Carbon in industrial swage Treatment
Activated carbon has strong physical and chemical adsorption functions, and also has detoxification effects. The detoxification effect is to use its huge area to adsorb toxins into the micropores of activated carbon, thereby preventing the absorption of toxins. Meanwhile, activated carbon can combine with various chemical substances to prevent their absorption.
（1）Activated carbon treatment of chromium containing wastewater
Activated carbon has a well-developed microporous structure and a high specific surface area, which has strong physical adsorption ability and can effectively adsorb Cr (VI) in wastewater. There are a large number of oxygen-containing groups on the surface of activated carbon, such as hydroxyl (- OH) and carboxyl (- COOH), which have electrostatic adsorption function and generate chemical adsorption on Cr (VI). It can be fully used to treat Cr (VI) in electroplating wastewater, and the adsorbed wastewater can meet the national discharge standards.
（2）Activated carbon treatment of cyanide containing wastewater
In industrial production, cyanide or byproduct cyanide is used in industries such as wet extraction of gold and silver, production of chemical fibers, coking, synthetic ammonia, electroplating, and gas production. Therefore, a certain amount of cyanide containing wastewater must be discharged during the production process, and activated carbon can be used for effective adsorption.
（3）Activated carbon treatment of mercury containing wastewater
Activated carbon has the ability to adsorb mercury and mercury containing compounds, but its adsorption capacity is limited and is only suitable for treating wastewater with low mercury content. If the concentration of mercury is high, it can be treated with chemical precipitation method first. After treatment, the mercury content is about 1mg/L, and can reach 2-3 mg/L at high temperatures. Then, activated carbon can be used for further treatment.
（4）Treatment of Phenolic Wastewater with Activated Carbon
Phenolic wastewater is widely sourced from petrochemical plants, resin plants, coking plants, and refining plants. Through experiments, it has been proven that activated carbon has good adsorption performance for phenol, and an increase in temperature is not conducive to adsorption, resulting in a decrease in adsorption capacity; But the time to reach adsorption equilibrium by increasing the temperature is shortened. There is an optimal value for the amount and adsorption time of activated carbon, and the removal rate does not change significantly under acidic and neutral conditions; Under strong alkaline conditions, the removal rate of phenol sharply decreases, and the stronger the alkalinity, the worse the adsorption effect.
（5）Activated carbon treatment of wastewater containing methanol
Activated carbon can adsorb methanol, but its adsorption capacity is not strong and is only suitable for treating wastewater with low methanol content. The engineering operation results show that the COD of the mixed liquid can be reduced from 40 mg/L to below 12 mg/L, and the removal rate of methanol can reach 93.16% to 100%. The effluent quality can meet the water quality requirements of the reused boiler desalination system.
How to choose high quality coconut shell activated carbon
Choosing high-quality coconut shell activated carbon requires considering several key factors. Activated carbon is widely used in various applications, such as gold extraction ,water purification, air filtration, gas adsorption, and more. Here are some important factors to consider when selecting high-quality coconut shell activated carbon:
1.Source of Coconut Shell:
The quality of the activated carbon is heavily influenced by the source of the coconut shells. Ensure that the coconut shells used are of high quality and free from contaminants, as this can impact the final product's effectiveness.
2.Activation Method:
The activation process greatly affects the characteristics of the activated carbon. There are two common activation methods: physical activation (e.g., steam activation) and chemical activation. Steam activation is preferred as it produces high-quality activated carbon with larger surface areas and excellent adsorption properties.
3.Surface Area and Pore Structure:
The efficiency of activated carbon depends on its surface area and pore structure. Higher surface area and a well-developed pore structure (micropores and mesopores) contribute to better adsorption capacity. The surface area is usually measured in square meters per gram (m²/g).
4.Adsorption Capacity:
The adsorption capacity of activated carbon determines its ability to remove impurities. It is measured by parameters like iodine number (mg/g) and methylene blue (mg/g). Higher values indicate better adsorption capabilities.
5.Particle Size:
The particle size of activated carbon can impact its performance in specific applications. Finer particles generally have more surface area and are more suitable for liquid phase applications, while coarser particles are often used in gas phase applications.
6.Ash Content:
Low ash content is essential for high-quality activated carbon. Excess ash can lead to undesirable side reactions and reduce the active sites available for adsorption.
7.pH and Moisture Content:
The pH and moisture content can influence the chemical properties and stability of activated carbon. Ensure that the pH is within an appropriate range, and the moisture content is minimized for better storage and handling.
8.Certification and Testing:
Look for activated carbon that meets international standards, such as ASTM (American Society for Testing and Materials) or ISO (International Organization for Standardization). Manufacturers may provide test reports showing key parameters like surface area, adsorption capacity, and impurity levels.
9.Application-Specific Considerations:
Different applications have specific requirements. Ensure the activated carbon you choose is well-suited for your intended use, such as drinking water treatment, air purification, or gold recovery.
10.Supplier Reputation:
Choose a reputable supplier with a track record of providing high-quality activated carbon. Customer reviews and testimonials can give insights into the supplier's reliability and product quality.
Remember to thoroughly research and compare different products and suppliers before making a purchase. By considering these factors, you can increase the likelihood of selecting high-quality coconut shell activated carbon for your specific needs.
