Liquid Regeneration of Spent Activated Carbons

New liquid phase-based processes to regenerate spent AC have been conducted. Two liquid processes, competitive adsorbate displacement and supercritical fluid (SCF) regeneration, will be discussed.

About The Author: 

Henry Nowicki, Ph.D., is the principal investigator for developing these liquid-based processes for regeneration of spent AC. He also is president of PACS and provides major organic and inorganic testing, ASTM activated carbon testing, BET surface areas and research and development for the AC industry. PACS provides 57 different public training courses including three courses related to activated carbon adsorption. He may be reached at 724-457-6576; e-mail hnpacs@aol.com

Exploring the Multifunctional Nature of Activated Carbon Filtration

Granular activated carbon (GAC) is commonly used for removing organic constituents and residual disinfectants in water supplies. Activated carbon is a favored water treatment technique because of its multifunctional nature and the fact that it adds nothing detrimental to the treated water.
