Activated Carbon in Effluent Treatment

Kalpaka is one among the best activated carbon producers offering KALBON PAC that giving the reliable solutions in the treatment of effluents.

Effluent treatment is a very critical component of any industrial process because it must ensure the discharge criteria and it should meet the process requirement as the water need to be reused at a facility or other. Since reuse of water is becoming increasingly very important, activated carbon plays a crucial role because of its versatility.

Industrial waste water often contains many impurities such as dissolved and undissolved substances, easily degradable or persistent organic substances, heavy metals, and salts. Activated carbon eliminates these unwanted substances.

Activated carbon (also called as active carbon) by its property of adsorption, it is used in both water and wastewater treatment applications. Adsorption processes are commonly used in municipal drinking water treatment to remove synthetic organic compounds (SOCs), taste and odor-causing, color-forming organics, and disinfection by-product (DBP) precursors.

Both PAC (Powder Activated Carbon) and GAC (Granular Activated Carbon) have its own merits and demerits in the field of effluent treatment. As per ASTM (American Society for Testing and Materials) PAC is the particles passing through an 80-mesh sieve (0.177mm) and smaller. Depending on specific application, by varying the manufacturing conditions, the pore structure is changed by giving unique adsorption properties specific to each product.

PAC is normally used in biological processes, where the organic toxic elements are removed. The carbon in the biological treatment process acts as a "buffer" against the effects of toxic organics in the wastewater. PAC stabilizes biological systems against upsets and shock loading, also it controls the color and odor. As it does many at time it supports the cost reduction more over it may reduce disposal costs while removing soluble organics.

In using GAC, a column is normally used as a means of contact between the water to be treated and the activated carbon, whereby the water enters through the lower part and ascends to the top part. In this case, the particulate size is bigger than in the other. The porous nature and large surface area of GAC make it specifically ideal for physical adsorption and other treatment techniques. It is normally used to eliminate trace elements, especially organic trace elements, that may be present in the water and that have usually resisted a biological treatment. Despite their low concentration, these elements often give the water a bad smell, color or taste. Hence it is obvious that PAC is more advantageous over GAC. But GAC has a very attractive option that it can be reused through reactivation.

Moreover, since the statutory regulations are becoming more and more stringent, the planning to face the current and future regulations can never be ruled out. To address these challenges and regulations the operators should look for the new technologies and the respective suppliers continuously and promptly without ignoring proper research and testing to ensure the best ways to treat the effluents.
