To meet the treatment requirements of the customers, manufacturers provide full line of adsorption equipment. These adsorption equipment include standard products as well as custom designed systems having variety of ranges in size. This air pollution control equipment is designed to be user friendly. The smaller cleaning equipment is portable and can easily be serviced on-site or disconnected and later reactivated. The larger adsorption system is designed to be installed quickly and easy to operate as the focus is on carbon reactivation, recovery and replacement. The manufacturers provide a spectrum variety of these industrial products like vapor phase adsorber, liquid phase adsorber, carbon adsorber and adsorption air cooled dryer. The consumers look for air quality control, pilot testing, soil vapor extraction, de-colorization, product purification and wastewater treatment in the required product. Some adsorption heat pump is effective in removing the solvent from the waste stream, but is unable to desorb (recover) the solvent from the activated carbon.
