If you’re in the water treatment business, you’re sure to be familiar with granular activated carbon (GAC), as it has be used for decades to control odor and taste problems, remove specific contaminants and act as a filtration media. Over the years water treatment technology has progressed, but GAC has remained a steadfast part of the treatment process. In fact, as ozone, ultraviolet (UV) light, and biologically enhanced activated carbon (BAC) have joined the ranks of common treatment methods, GAC has shown just how versatile, synergistic, and effective it really is. CH2M HILL has done numerous studies and designed over a billion gallons per day of GAC plant capacity that showcase the synergistic effects of GAC. We are pleased to share the results of a few of these efforts with you in our article, “GAC Treatment: A Versatile Technology Stands the Test of Time,” featured in the January edition of American Water Works Association’s Opflow magazine, so you can learn more about all that GAC continues to provide the water treatment industry.
Tony Myers is a drinking water treatment expert involved in the study, design and construction of many water treatment plants over the past 27 years.
Roger Scharf is a staff engineer working on water, wastewater and water resources projects. He has five years of experience working on taste and odor identification and removal from drinking water.
