Water Quality Products invited Joseph F. Harrison, P.E., CWS-VI, technical director of the WQA, to give an overview of the issues discussed at the association’s Mid-Year Leadership Conference held Sept. 6 to 8, 2006, in Park City, Utah.
Activated carbon is an excellent adsorbent due to its large surface area and the fact that the diverse surfaces can take on many different types of contaminants.
Broad spectrum removal filter media—overview
Various authors have studied the use of activated carbon and for the most part have concluded activated carbon is not a cost-effective solution. However, these authors have failed to realize the limitations of carbon validation methods or the fact that not all carbons are alike, especially when chemical reactions control the process.
The 8th Annual International Activated Carbon Conference (IACC-8) and optional training courses took place on Sept. 18—23. This article provides a brief review of some of the activities and summaries of the speakers’ topics.
Granular activated carbon (GAC) is commonly used for removing organic constituents and residual disinfectants in water supplies. This not only improves taste and minimizes health hazards, it protects other water treatment units such as reverse osmosis membranes and ion exchange resins from possible damage due to oxidation or organic fouling. 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.
Many filtration products are available. Asking the correct questions is important in obtaining an optimum product for the desired application.
Activated carbon is like a radio: everyone knows it works, but few people know exactly how. This article is a brief summary of the sources of carbons, the activation process, the principle of adsorption, and the range of current applications.
