Activated carbon in sewage treatment
2020年11月7日Wastewater treatment is a critical component of any industrial process because it must ensure discharge standards and meet process requirements because water needs to be reused at facilities or elsewhere. As the reuse of water becomes more and more important, activated carbon plays an important role because of its versatility.
Industrial wastewater usually contains many impurities, such as dissolved and insoluble substances, degradable or persistent organic substances, heavy metals and salts. Activated carbon eliminates these harmful substances.https://www.yrdcarbon.com/products/
Activated carbon can be used in water and wastewater treatment because of its adsorption characteristics. Adsorption process is usually used in municipal drinking water treatment to remove synthetic organic compounds (SOC), organics causing taste and odor, color forming organics and precursors of disinfection by-products (DBP).
PAC (powdered activated carbon) and GAC (granular activated carbon) have their advantages and disadvantages in the field of wastewater treatment. According to ASTM, PAC is particles passing 80 mesh (0.177 mm) or smaller sieve. According to the specific application, by changing the manufacturing conditions, the pore structure can be changed by giving each product unique adsorption properties.
PAC is usually used in biological processes to remove toxic organic elements. Carbon in the biological treatment process acts as a "buffer", which can resist the influence of toxic organic compounds in wastewater. PAC can stabilize the biological system from discomfort and shock load, and can control color and odor. Because it supports cost reduction in many cases, it can reduce treatment costs and remove soluble organic matter.
When GAC is used, the tower is usually used as a means of contact between the water to be treated and the activated carbon, so that the water enters through the lower part and rises to the top. In this case, the particle size is larger than other particle sizes. The porous nature and large surface area of GAC make it particularly suitable for physical adsorption and other treatment technologies. It is usually used to remove trace elements, especially organic trace elements, that may exist in water and are usually difficult to be biologically treated. In spite of their low concentrations, these elements usually give water an unpleasant smell, color or taste. Therefore, it is obvious that PAC has more advantages than GAC. But GAC has a very attractive option to reuse by reactivating it.https://www.coconutactivatedcarbon.com/
Moreover, as statutory regulations become more stringent, plans to face current and future regulations cannot be ruled out. In order to meet these challenges and regulations, operators should continuously and rapidly find new technologies and their respective suppliers without neglecting appropriate research and testing to ensure the best wastewater treatment methods.
