In the tertiary treatment of industrial wastewater, powder activated carbon is often used for advanced treatment to reduce the COD value, achieve the purpose of wastewater reuse, reduce the waste of water resources, reduce the cost of enterprises, and achieve reuse.
Powdered activated carbon has a huge specific surface area and developed pore structure. By treating the water quality of industrial wastewater by physical adsorption, organic matter and heavy metals in wastewater can be effectively removed and decolorized. The operation is relatively simple.
The iodine adsorption value of powder activated carbon produced by activated carbon manufacturers is 900~1200mg/L, which can be customized according to customer needs. The adsorption value of methylene blue is greater than 180mg/L, the purification efficiency is high, and the adaptability is strong.
It is worth noting that powdered activated carbon is not easy to be recycled after use, and it is difficult to regenerate. Generally used for intermittent water treatment processes with heavy pollution.
Powdered activated carbon can be used alone as a process to treat industrial wastewater, or it can be used in combination with other processes to achieve wastewater purification. Separate treatment requires the use of a large amount of powdered activated carbon, which is relatively expensive. Generally, enterprises use other means to reduce pollution, and then use powdered activated carbon for fine treatment to meet industrial wastewater reuse standards or discharge standards.
