Technologies: Activated Carbon Adsorption

Activated carbon technology is utilised by Wehrle for the removal of non-biodegradable COD and halogenated hydrocarbons (AOX). For example, wastewater from medicine production can be treated with a combination of biological and activated carbon processes, thereby ensuring the complete removal of endocrine mimicking compounds. In the chemical industry, activated carbon can be employed to remove non-biodegradable COD. Another application is the polishing of membrane bioreactor-treated leachate from landfill sites.

The adsorption of organic contaminants using activated carbon is based on a physical process that takes place on the surface of the activated carbon. Due to a highly developed pore system, activated carbon has an extremely large inner surface area. The concentration gradient of the material that is adsorbed is the driving force behind the adsorption process. Once the activated carbon is completely loaded it can be removed and replaced with fresh activated carbon.

Wehrle uses activated carbon both as a primary treatment process and a secondary one following biological pretreatment.
