What is the price of powdered activated carbon?

Powdered activated carbon plays an important role in the modern water treatment industry. Due to its strong adsorption capacity and wide application fields, it has become one of the preferred materials for many companies in water treatment projects. So, how much does powdered activated carbon cost per ton? What are its specific applications in water treatment? JS Activated Carbon will answer these questions in detail for you and help you choose the appropriate type of activated carbon and dosing method.

1. Types and prices of powdered activated carbon

Powdered activated carbon pac can be divided into coal-based powdered carbon, wood-based powdered carbon, fruit shell powdered carbon, etc. according to different raw materials. Powdered activated carbon made from different raw materials has different adsorption properties and prices. Coal-based powdered carbon is the most widely used in the water treatment industry, especially suitable for sewage treatment.

In terms of price, the price of coal-based powdered activated carbon fluctuates greatly, mainly depending on its adsorption performance indicators such as iodine value and pore structure. For example, the price of common 800 iodine powdered activated carbon is about 4,500 to 5,500 yuan/ton, while the price of activated carbon with higher iodine value or other better performance can even be as high as 8,000 yuan/ton or more. This price difference is mainly due to the production process of activated carbon, the cost of raw materials and its adsorption performance.

2. Characteristics and advantages of powdered activated carbon:

Powdered activated carbon has a dark black appearance, high porosity and large specific surface area, which gives it excellent adsorption capacity. In addition, it also has the following significant characteristics:

Good chemical stability: Powdered activated carbon can remain stable in both acidic and alkaline environments, is resistant to strong acids and alkalis, and is suitable for various water treatment processes.

High temperature and water immersion resistance: Powdered activated carbon can operate stably in high temperature environments and will not decompose or deteriorate after long-term immersion in water.

Strong hydrophobicity: The hydrophobicity of powdered activated carbon enables it to better adsorb organic matter, especially when removing harmful chemicals from water.

3. Application of powdered activated carbon water treatment:

Powdered activated carbon is widely used in water treatment, mainly for removing dissolved organic matter, color, odor, etc. in water. During the treatment process, it has a strong adsorption capacity for the following substances:

Organic matter: such as trihalomethanes and their precursors, benzene, phenols and other organic compounds.

Chemical pollutants: such as carbon tetrachloride, pesticides, herbicides, synthetic dyes, etc.

Metal ions: such as mercury, aluminum, iron, nickel, zinc and other heavy metal ions.

These substances are often difficult to remove through simple physical methods during water treatment, while powdered activated carbon can effectively remove these harmful substances due to its rich pore structure and strong adsorption performance. However, it should be noted that powdered activated carbon has a poor effect on the removal of ammonia nitrogen, and it needs to be combined with other processes for comprehensive treatment in the treatment of wastewater containing more ammonia nitrogen.

4. Comparison of different types of powdered activated carbon:

There are many types of powdered activated carbon, mainly due to the different raw materials used in manufacturing. Common raw materials for powdered activated carbon include: wood, coconut shells, fruit shells, coal, etc. Among them, wood powdered carbon and coal powdered carbon are the most widely used in water treatment, but they have significant differences in adsorption performance, price, etc.:

Wood powder charcoal: Wood powder charcoal usually has well-developed pores and is mainly used to adsorb large molecular organic matter. It is suitable for treating more complex organic pollutants. It has a fast adsorption rate and is suitable for quickly dealing with water quality problems when dealing with sudden pollution.

Coal-based powdered carbon: Coal-based powdered carbon performs better in removing low-concentration organic pollutants and has a relatively low price, making it an economical choice for most water treatment plants.

Coconut shell powder carbon: The pore structure of coconut shell powder carbon is very suitable for adsorbing low molecular weight organic matter, and is especially suitable for removing trace organic pollutants.

5. Dosing method of powdered activated carbon:

In the water treatment process, the dosing method of powdered activated carbon directly affects its adsorption effect. There are two main dosing methods: dry dosing and wet dosing.

Wet dosing: Wet dosing is to prepare powdered activated carbon into a suspension and then add it quantitatively. The concentration of the suspension is usually around 5%. Too high a concentration can easily cause equipment clogging. This method has uniform dosing and good adsorption effect, and is particularly suitable for long-term, large-scale water treatment applications.

When choosing the dosing method, attention should also be paid to the selection of the dosing point. Several cubic meters of powdered activated carbon should be added before coagulants and chlorine to avoid reducing its adsorption capacity. In addition, in order to ensure the full play of activated carbon, it is necessary to ensure that there is at least 30 minutes of contact time after addition.

6. The relationship between the particle size and performance of powdered activated carbon:

The adsorption performance of powdered activated carbon is not only related to its raw materials and manufacturing process, but also closely related to its particle size. Generally speaking, the smaller the particles, the larger the specific surface area per unit volume, and the better the adsorption effect, but too large a mesh size will increase the risk of penetrating the filter tank, which may have a negative impact on the water treatment system.

7. The importance of powdered activated carbon:

The application of powdered activated carbon in water treatment is undoubtedly of great significance. Its excellent adsorption performance makes it an effective tool for removing harmful organic matter in water. However, different types of powdered activated carbon vary in price, performance and scope of application. Enterprises need to comprehensively consider water quality characteristics, cost factors and adsorption effects when choosing. At the same time, reasonable dosing methods and appropriate particle size selection can further improve the use effect of powdered activated carbon and ensure high efficiency and stability in the water treatment process.
