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.
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%.
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.
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.
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%.
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.
