Activated carbon
Activated carbon is commonly used to adsorb natural organic compounds, taste and odor compounds, and synthetic organic chemicals in drinking water treatment. Adsorption is both the physical and chemical process of accumulating a substance at the interface between liquid and solids phases. Activated carbon is an effective adsorbent because it is a highly porous material and provides a large surface area to which contaminants may adsorb. The two main types of activated carbon used in water treatment applications are granular activated carbon (GAC) and powdered activated carbon (PAC).
GAC is made from organic materials with high carbon contents such as wood, lignite and coal. The primary characteristic that differentiates GAC to PAC is its particle size. GAC typically has a diameter ranging between 1.2 to 1.6 mm and an apparent density ranging between 25 and 31 lb/ft3), depending on the material used and manufacturing process. The bed density is about 10 percent less than the apparent density and is used to determine the amount of GAC required to fill a given size filter. The uniformity coefficient of GAC is quite large, typically about 1.9, to promote stratification after backwashing and minimize desorption and premature breakthrough that can result from mixing activated carbon particles with adsorbed compounds with activated carbon particles with smaller amounts of adsorbed compounds. Iodine and molasses numbers are typically used to characterize GAC. These numbers describe the quantity of small and large pore volumes in a sample of GAC. A minimum iodine number of 500 is specified for activated carbon by AWWA standards.
ACTIVATED CARBON FILTERS: Function
Activated carbon filters provide one of the most effective methods for removing odours and gaseous contaminants. Among their most common uses are in museums and galleries to remove sulphur dioxide, nitrogen dioxide and nitric oxide that cause serious damage to exhibits; kitchen extract systems to remove odours; the printing industry for the removal of ozone; and many industrial processes for both odour and gas removal.
ACTIVATED CARBON FILTERS: Selection & Operation
Activated carbon comes in two forms: base carbon and impregnated carbons. While base carbons are suitable for most applications, impregnation will enhance its ability with respect to certain types of gaseous contaminant. Selection therefore requires notification of the types of contaminant to be removed, along with details on air flow and filter measurements to determine the most appropriate format.
