Coal activated carbon powder is a finely ground material derived from coal through a process of high-temperature activation in the absence of oxygen. This treatment creates a porous structure with a large surface area, allowing the powder to effectively adsorb contaminants from both gases and liquids. It is widely employed in water and wastewater treatment, air purification systems, and various industrial processes where its ability to remove pollutants, odors, and impurities is highly valued. The fine particle size of coal activated carbon powder facilitates rapid adsorption kinetics, making it a versatile and efficient solution in environmental and purification applications.
This blog will forcus to introduce the different application of coal activated carbon powder.
Coal can be processed into the different types of granular, pellet, and powder activated carbon. The most cost effective is coal-based activated carbon powder, which has low competition, large sales volume, and sufficient supply.
It has wide applications.
Waste incineration
In the past, people adopted the method of filling and medicament to eliminate garbage, which was destroyed in decades and caused pollution. Since 1990, waste incineration has been applied, and the cost of waste disposal has increased from 54RMB/t to 67RMB/t. The reason is the rise of raw materials and the government improves the environmental requirements.
China's emission standard: national standard GB18485-2014
Emission standard: dioxin 0.1Ng
Mercury: 0.05mg/Nm3
Cadmium: 0.1mg/Nm3
Lead: 1mg/Nm3
SO2: 20mg/Nm3
CO: 50mg/Nm3
HCL: 250mg/Nm3
HF (hydrogen fluoride): 80mg/Nm
After incineration, it will produce ammonia, nitrogen, sulfur and nitrogen oxides will be produced
Kitchen waste: Dioxins
Metals: Fe, Pb, Cr, Hg, Cu
Leather: sulfur, hydrogen, HCL
Rubber: HF
For waste incineration, zhulin carbon can provide 800-900 iodine value coal activated carbon powder, which can absorb various waste gas by spraying way.
Wastewater treatment
For example, it is often applied in industrial (Coke Factory) waste water biological treatment pools, it is used as an adjunct to the bacteria and COD that perform biological treatment.
The coal activated carbon powder will be added to equalization tank. Flow equalization tanks are most often located at the wastewater treatment plant and are designed to provide storage to accommodate the variable flow into the tank and output a steady state condition that would flow into the treatment plant, which optimizes the efficiency of the treatment process.
The wastewater mainly contains phenolic pollutants, cresol and ethyl phenol. And most is mainly acidic. The PH of coal activated carbon is alkaline, which is neutral to the acidity and neutralization of wastewater.
Wastewater contains more negative ions, hydroxy-OH. Coal is conductive and has more positive ions, which can lead neutralization of positive and negative ions.
The following is our activated carbon for COD and ammonia nitrogen removal index:
Item in waste water | Before | After |
COD content | 300-400mg/l | <80mg/l |
Ammonia nitrogen content | 300-400mg/l | <25mg/l |
Soil improvement:
- Removing geosmin
- PFAS removal for soil purfication
Urban sewage treatment, water plant:
removing organic matter (humic acid), that is, adjusting the pH value, residual chlorine, reducing turbidity, decoloring, removing heavy metals.
