Carbon Adsorption Systems
Carbon Adsorption Systems
Also known as Dry Scrubbers, Carbon Adsorbers, or Physical Adsorption Systems
KCH designs and manufacturers a Carbon Adsorption System which is one of the most effective in removing total odors and VOCs from municipal and industrial processes. Designed for continuous use and built to withstand the elements, our Activated Carbon, Zeolite, or Activated Alumina-based Adsorption Systems can be used exclusively or in conjunction with other Air Pollution Control Technologies, such as Wet Chemical Scrubbers or Biotrickling Filters. Where certain applications require adsorption in combination with chemisorption, KCH offers a chemical impregnated adsorption media to achieve ultimate performance.
The standard KCH Carbon Adsorption System is comprised of a vertical, cylindrical vessel with a domed or conical top. They are constructed in our facility from POLYLAST®, POLYSTRONG®, or other corrosion-resistant materials. KCH Vessels feature exceptional corrosion resistance and UV resistance, making them ideal for long-term intended service life and outdoor installations as required. KCH also provides dual bed carbon adsorbers and radial flow carbon adsorbers. Activated Carbon is often used for odor control at Municipal Waste Water Treatment Facilities and Lift Stations.

HOW IT WORKS
Carbon adsorbers use a dry media to capture odor or VOC’s from an airstream through physical adsorption of the contaminant by a highly porous media. Typically a three foot deep media bed is supported above the air inlet. Air travels vertically through the media and exhaust out the top. The media comes in powdered, granular, extruded, and pelletized form and can be made from coal, coconut shells, zeolite, or other porous material. It can be impregnated with chemicals to increase its adsorption qualities.
KCH offers Single Bed Carbon Adsorbers, Dual Bed Carbon Adsorbers, or Radial Flow Carbon Adsorbers in standard sizes. Radial type carbon adsorbers can maximize airflow volume in a much smaller foot print.
Please contact a KCH Representative for your specific application.
KCH Activated Medias
Depending on the application for adsorption, KCH provides 5 different types of activated media. We often also use a proprietary blend of medias for added capacity to adsorb a combination of vapors. Below is our standard media for H2S Applications. Please contact KCH Sales for additional types.
