When choosing activated carbon, many customers tend to focus only on price for cost reasons, ignoring the importance of quality. However, high quality activated carbon can greatly improve the adsorption effect and reduce the long-term use cost, as well as reduce the impact on the environment. HUAMEI Activated Carbon will analyse in detail why cheaper activated carbon is more expensive, and the difference between high quality activated carbon and low quality activated carbon.

1. Cost comparison between high-quality activated carbon and low-quality activated carbon

Poor-quality activated carbon usually attracts consumers, especially customers with limited budgets, with a lower per-unit cost (or even false indicators). However, such short-term savings often lead to higher costs in long-term use. The main problems with low-quality activated carbon include high ash content and high density, which means that bad quality activated carbon weighs much more than good quality carbon in the same volume of carbon box, which increases transport costs. In addition, lower-quality activated carbon has poor adsorption capacity and a short service life, requiring frequent replacement and increasing disposal costs.

On the other hand, although the price per ton of high-quality activated carbon is higher, its ash content is low, density is less, and the adsorption effect is significantly better. Under the same conditions, the service life of premium activated carbon is longer, which reduces the frequency of replacement and thus lowers the long-term cost of use. Considering the purchase, transport and disposal costs, the cost-effectiveness of high-quality activated carbon is higher. After market research, the use of high quality activated carbon can reduce the total cost by about 20%.

2. Difference in adsorption performance: high iodine value VS low iodine value activated carbon

The iodine value of activated carbon is an important indicator of its adsorption capacity. Generally, the higher the iodine value, the stronger the adsorption capacity of activated carbon. Activated carbon with a high iodine value has a larger specific surface area and stronger adsorption capacity, which can more effectively remove harmful substances in the air, such as VOCs, harmful gases and pollutants.

3. The following is a comparison of the adsorption performance of high iodine value and low iodine value activated carbon:

High iodine number activated carbon (iodine value ≥ 800mg/g):
It can adsorb more pollutants, and the purification effect is remarkable. Fast adsorption speed, can remove a large number of harmful substances in a short time. Long service life, reducing the frequency of replacement, reducing the long-term cost of the enterprise. It is suitable for high-efficiency filtration and deep purification, and is widely used in industrial waste gas treatment, drinking water purification and other fields.

Low iodine number activated carbon (iodine number ≤ 500mg/g):
Limited adsorption capacity, only suitable for lightly polluted environment. Frequent replacement is required, which increases the cost of use and the complexity of operation. Poor effect on large air volume processing system, unable to meet the demand for high efficiency filtration.

Research shows that the adsorption effect of low iodine value activated carbon is about 1/3 of that of high iodine value activated carbon, so although it is cheaper, it is far inferior to the latter in terms of adsorption effect, service life and overall cost.the adsorption effect of high-quality activated carbon is better, which can reduce the emission of harmful substances and the risk of environmental pollution. Secondly, high-quality activated carbon can be desorbed and used again through regeneration technology after adsorption saturation.

4. How to identify high quality activated carbon?

In order to avoid purchasing poor-quality activated carbon, enterprises need to master some simple and effective identification methods during the procurement process.

Appearance observation: high-quality activated carbon is usually dark black in colour and has a short and straight shape, while low-quality activated carbon shows a greyish or rusty colour and has a long and curved shape.
Weight comparison: under the same volume, high-quality activated carbon is less dense and lighter in weight, while low-quality activated carbon is obviously heavier due to its higher density.

Bubble test: When the activated carbon is put into the water, high-quality activated carbon will produce continuous tiny bubbles, accompanied by "hissing" sound, and float up and down in the water. Inferior activated carbon sinking speed, less or no bubbles, no obvious movement after settling.

Physicochemical testing: Through laboratory testing, the iodine value of high-quality activated carbon should be more than 800mg/g, and the ash content is less than 15%; while the iodine value of poor-quality activated carbon is usually less than 500mg/g, and the ash content is more than 15%.

5. Summary

High-quality activated carbon has significant advantages in adsorption performance, service life and environmental protection benefits, etc. Although the initial purchase cost is higher, its cost performance is obviously better than that of low-quality activated carbon in the long run. The adsorption effect of activated carbon with high iodine value is significantly better than that of activated carbon with low iodine value, and it can remove pollutants more effectively, prolong its service life, reduce the frequency of replacement, and lower the cost of long-term use.

Therefore, when purchasing activated carbon, enterprises should avoid focusing only on the price, but should comprehensively consider the performance, adsorption capacity and environmental benefits of activated carbon, and choose high-quality activated carbon, which not only helps enterprises to improve production efficiency, but also meets the requirements of environmental protection regulations and realises sustainable development.

Introduction to Activated Carbon

Activated carbon as a widely used material in various fields, especially in environmental applications. Huamei Activated Carbon Company is an important and influential activated carbon manufacturer in China.
Activated carbon is a remarkable material that finds extensive applications in multiple domains. It is particularly crucial in environmental sectors due to its exceptional adsorption properties.
Activated carbon is available in different forms, including powdered, granular, and as part of composites like polyamide - activated carbon. Powdered activated carbon has an extremely fine particle size, offering a vast total surface area and consequently, an extremely high adsorption capacity. However, its small particles can slow down filtration processes and often require pressurization or depressurization during filtration operations. Granular activated carbon, on the other hand, is made from powdered activated carbon and has a slightly smaller total surface area compared to its powdered counterpart. Still, it maintains a significant adsorption capacity and is easier to handle during filtration.
The adsorption capacity of activated carbon makes it an invaluable tool in environmental applications. For instance, in wastewater treatment, it can adsorb a wide range of contaminants, including organic compounds and certain inorganic substances. In air purification systems, it helps remove harmful gases and odors. With a specific surface area that can exceed 1000 m²/g, a small amount of activated carbon can have a tremendous impact on purifying the environment.

Activated Carbon in Wastewater Treatment History

1. Early Adoption

In 1965, a significant milestone was reached with the establishment of the first full-scale advanced wastewater treatment plant incorporating granular activated carbon (GAC). This marked the beginning of a new era in wastewater treatment. The use of GAC in this plant demonstrated its potential to effectively remove contaminants that were difficult to treat with traditional methods.

2. Widespread Use

As time passed, GAC beds became increasingly common in tertiary treatment. Tertiary treatment is the final stage in the wastewater treatment process, aimed at removing residual contaminants and polishing the water to a higher quality. GAC is highly effective in this stage as it can adsorb a wide range of organic compounds and certain inorganic substances that may have survived previous treatment stages.
The widespread use of GAC in tertiary treatment is due to several factors. Firstly, its high adsorption capacity allows it to remove even trace amounts of contaminants, ensuring that the treated water meets stringent environmental standards. For example, studies have shown that GAC can effectively remove pesticides, pharmaceuticals, and personal care products from wastewater.
Secondly, GAC beds are relatively easy to operate and maintain. They can be designed to fit into existing treatment plants with minimal modifications, making them a cost-effective solution for upgrading wastewater treatment facilities.
Moreover, the use of GAC in wastewater treatment has gained widespread acceptance due to its environmental benefits. By removing contaminants from wastewater, it helps protect aquatic ecosystems and reduces the risk of waterborne diseases.
In conclusion, the history of activated carbon in wastewater treatment is a story of innovation and progress. From its early adoption in 1965 to its widespread use in tertiary treatment today, activated carbon has proven to be an invaluable tool in purifying wastewater and protecting the environment.

Applications in Industrial Wastewater Treatment

1. As a Separate Unit Process

Activated Carbon for Wastewater Treatment can function as a crucial separate unit process in industrial wastewater treatment. In many industrial settings, where the wastewater contains a complex mixture of contaminants, activated carbon can be employed to target specific pollutants that are difficult to remove by other means. For instance, in the electronics industry, wastewater may contain heavy metals and organic solvents. Activated carbon can effectively adsorb these contaminants, reducing their concentration to levels that meet regulatory standards.
Studies have shown that in some cases, the use of activated carbon as a separate unit process can achieve removal efficiencies of up to 90% for certain contaminants. This high removal efficiency makes it an attractive option for industries looking to comply with strict environmental regulations.

2. As an Advanced Treatment Step

After biological treatment, activated carbon can be used as an advanced treatment step to remove refractory organics. Biological treatment is often effective in removing biodegradable organic matter from wastewater. However, some organic compounds are resistant to biological degradation and can remain in the effluent. Activated carbon can adsorb these refractory organics, further improving the quality of the treated water.
For example, in the pharmaceutical industry, wastewater may contain complex organic compounds that are difficult to remove by biological treatment alone. By adding an activated carbon treatment step after biological treatment, these refractory organics can be effectively removed, ensuring that the effluent meets the stringent environmental standards required for discharge.
The placement of activated carbon as an advanced treatment step also offers several advantages. It can enhance the overall treatment efficiency of the wastewater treatment system and reduce the risk of environmental pollution. Additionally, it can help industries reduce their reliance on chemical treatment methods, which can be expensive and environmentally unfriendly.

Advantages and Considerations

1. Advantages

Activated carbon offers several significant advantages in wastewater treatment. One of the most notable is its high treatment degree. Due to its exceptional adsorption properties, it can effectively remove a wide range of contaminants, including organic compounds, heavy metals, and certain inorganic substances. This results in highly treated water with a significantly reduced pollutant load. For example, in some industrial wastewater treatment applications, activated carbon can reduce the concentration of contaminants to levels that are well below regulatory limits.
In addition to its high treatment effectiveness, activated carbon also provides stable water quality. Once the adsorption process is established, it can consistently remove contaminants over an extended period. This stability is crucial for industries that require a reliable source of clean water for their processes. Unlike some other treatment methods that may be affected by changes in water composition or flow rate, activated carbon maintains its performance, ensuring a consistent output of high-quality treated water.

2. Cost Considerations

While activated carbon is highly effective in wastewater treatment, its use comes with certain cost considerations. The initial cost of purchasing activated carbon can be significant, especially for large-scale treatment operations. Different types of activated carbon, such as powdered, granular, and composite forms, have varying price ranges depending on their adsorption capacity and other properties. For example, granular activated carbon is generally more expensive than powdered activated carbon due to its easier handling and longer lifespan.
In addition to the purchase cost, there are also expenses associated with the replacement and regeneration of activated carbon. Over time, the adsorption capacity of activated carbon diminishes as it becomes saturated with contaminants. Regular replacement or regeneration is necessary to maintain its effectiveness. The cost of regeneration can vary depending on the method used and the type of contaminants adsorbed. Some regeneration methods may involve thermal treatment or chemical washing, which can add to the overall cost of wastewater treatment.
Moreover, the handling and disposal of spent activated carbon also pose cost challenges. Spent activated carbon is classified as a hazardous waste in some cases due to the presence of adsorbed contaminants. Proper disposal methods must be employed to ensure environmental compliance, which can be expensive. For example, some industries may need to engage specialized waste management companies to handle the disposal of spent activated carbon.
Despite these cost considerations, the benefits of using activated carbon in wastewater treatment often outweigh the costs. The high treatment degree and stable water quality it provides can lead to significant savings in the long run by reducing the risk of environmental fines, improving process efficiency, and protecting aquatic ecosystems.

Conclusion

Activated carbon plays a crucial role in wastewater treatment. Its unique adsorption properties make it an invaluable tool for removing a wide variety of contaminants, ensuring cleaner water and a healthier environment.
Throughout history, activated carbon has evolved from its early adoption in 1965 to becoming a staple in tertiary treatment and industrial wastewater processes. Its ability to function as a separate unit process or an advanced treatment step gives industries multiple options for customizing their wastewater treatment systems.
The preparation of sludge activated carbon not only provides a sustainable solution for dealing with waste sludge but also offers a new source of high-performance activated carbon. Microwave radiation methods, in particular, show great promise for efficient and eco-friendly production.
The treatment principles and adsorption mechanisms of activated carbon, including physical adsorption and chemical adsorption, work in tandem to purify wastewater. The large specific surface area and porous structure of activated carbon enable it to attract and hold contaminants, while chemical adsorption provides an additional mechanism for removing certain difficult-to-treat substances.
Despite the cost considerations associated with activated carbon, its advantages in terms of high treatment degree and stable water quality cannot be ignored. As environmental regulations become more stringent and industries strive for sustainable operations, the demand for effective wastewater treatment solutions like activated carbon is likely to increase.
Looking to the future, activated carbon holds great potential for further innovation and application. Research and development efforts can focus on improving the adsorption capacity, reducing production costs, and developing more efficient regeneration methods. Additionally, the integration of activated carbon with other treatment technologies may offer even more effective solutions for complex wastewater treatment challenges.
