The unique, porous structure and vast surface area of activated carbon, combined with attraction forces, allows activated carbon to capture and hold various types of materials onto its surface.Activated carbon comes in many forms and varieties. It is produced by processing a carbonaceous material, most often coal, wood, or coconut husks, in a high temperature environment such as a rotary kiln in order to “activate” the carbon and create the highly porous surface structure.coconut shell granular activated carbon

Various forms of activated carbon exist, each offering different material characteristics that make it ideally suited for specific applications. As such, manufacturers offer a wide array of activated carbon products.Depending on the application, activated carbon may be used in powdered, granular, extruded, or even liquid form. It may be used alone, or combined with different technologies, such as UV disinfection.Water treatment systems typically employ either granular or powdered activated carbon, with granular activated carbon (GAC) from bituminous coal being the most commonly utilized form.


Removal of Contaminants

Activated carbon helps to ensure that water destined for consumption is removed of harmful contaminants such as pesticides, endocrine disruptors, and pharmaceutical products.

Taste and Odor Control

Activated carbon is also employed in reducing components that result in undesirable tastes and odors.

Disinfectant By-Products

Activated carbon has also been more recently utilized in controlling disinfectant by-products, or DBPs at drinking water treatment facilities.

DBPs are formed when the disinfectants used to treat water combine with the natural organic matter (NOM) present in the water to form harmful by-products. Activated carbon has proven to offer an effective approach in removing the precursors (NOM) of disinfectant by-products.


Activated carbon is also employed in both municipal and industrial wastewater treatment facilities. The effluent discharged either as municipal wastewater, or the discharge from an industrial process can contain a variety of components that must be removed before they are discharged into waterways or reused.

In these settings, activated carbon helps to protect waterways from contaminants such as pesticides, fuels, and various solvents, to name a few. Here again, activated carbon captures the targeted components for removal, rendering the water sufficient for discharge or its intended reuse application.

Process Water

In addition to dedicated water treatment facilities, many industrial facilities may host their own on-site operation to treat incoming municipal water for use in their specific industrial process. Process water used in the production of beverages, pharmaceutical products, and the like, must often meet highly strict requirements so as not to damage equipment or result in an inferior product.

Process water applications commonly rely on activated carbon to ensure water quality meets the requirements of its intended use.

For all of these water treatment applications, activated carbon can be employed in a number of ways. In each setting, activated carbon may be used alone, or in combination with other treatment methods, such as UV disinfection and/or particulate filtration systems.wood activated carbon suppliers
