Activated carbon (AC) is a common component in many water treatment devices. It removes a wide variety of organic-based contaminants, as well as some inorganic contaminants such as free chlorine and monochloramine. It is common to use AC ahead of reverse osmosis and ion exchange resins to prevent oxidation and organic fouling and to decrease maintenance frequency.
Activated Carbon Properties
Activated carbon properties determine filtration performance
CA Ware Coconut Shell Carbon Block Cartridges from H20 Filter Warehouse offer an inexpensive alternative to cartridges made with bituminous coal. Many people have switched from the more expensive coal cartridges to the 10 in. by 2.5 in. micron carbon block filter cartridges—CBC-10(5). Cartridges are available for immediate shipment.
This proprietary custom-made carbon formulation consists of powdered KDF media bonded onto the surface of granular activated carbon (GAC). This media controls the buildup of bacteria, algae and fungi, which is often associated with bad tastes and odor in GAC filters. It has enhanced filter performance compared with traditional GAC filters and minimal carbon fines are released.

Water Quality Products invited Joseph F. Harrison, P.E., CWS-VI, technical director of the Water Quality Association (WQA), to give an overview of current industry issues and what to expect at the upcoming Mid-Year Leadership Conference, to be held Sept. 5-7 in Nashville, Tenn.
Water Quality Products invited Derek Rowley, product manager for Pentair Filtration, to comment on the carbon anti-dumping issue as it relates to Pentair Water and the water treatment industry as a whole.
Drinking water treatment professionals have long held fast to the belief that granular activated carbon (GAC) based on bituminous coal provides the best performance for their demanding application. That’s why, when an article in 1999 cited evidence that a lignite-based GAC outperformed a bituminous-based carbon, industry experts were surprised and more than a bit skeptical.

Like an international cookbook, the attendees of the Ninth Annual International Activated Carbon Conference (IACC) from around the world contributed to a recipe for a successful future for the activated carbon industry. Speakers brought their new ideas and on-going practices together. This annual conference had guests from all over the United States, Canada, Australia, Sri Lanka, Indonesia, Mexico, South Africa and India. The conference connects buyers, sellers and users of activated carbon and related materials and services.
