Granular Activated Carbon Filter (GAC)


Product Details:



A Granular Activated Carbon (GAC) filter is a type of water filtration system that uses activated carbon granules to remove contaminants from water. Here are the key details of a GAC filter:

  1. Activated Carbon Media: The primary component of a GAC filter is granular activated carbon, which is a highly porous form of carbon with a large surface area. This porous structure allows the activated carbon to adsorb a wide range of contaminants from water, including chlorine, volatile organic compounds (VOCs), chemicals, pesticides, and unpleasant odors.

  2. Filtration Mechanism: As water passes through the GAC filter, contaminants in the water are attracted to the surface of the activated carbon granules and become trapped within its pores through a process called adsorption. This effectively removes impurities from the water, resulting in cleaner, clearer, and better-tasting water.

  3. Versatility: GAC filters are versatile and can be used for various water treatment applications, including point-of-use filtration (e.g., under-sink filters, countertop filters) and point-of-entry filtration (e.g., whole-house filtration systems). They are also commonly used in commercial and industrial settings for water purification.

  4. Removal of Chlorine and VOCs: One of the primary benefits of a GAC filter is its ability to remove chlorine and VOCs from water. Chlorine is commonly added to municipal water supplies for disinfection, but it can impart an unpleasant taste and odor to the water. GAC filters effectively reduce chlorine levels, resulting in improved water quality and taste.

  5. Reduction of Odors: In addition to chlorine, GAC filters can also remove other organic compounds that contribute to unpleasant odors in water. This helps enhance the overall aesthetic quality of the water, making it more palatable and enjoyable to drink.

  6. Longevity and Maintenance: The lifespan of a GAC filter depends on factors such as water usage, the concentration of contaminants in the water, and the size of the filter. Generally, GAC filters have a longer lifespan compared to some other types of filters, but they still require periodic replacement to maintain optimal performance.

  7. Pre- and Post-Filtration: GAC filters can be used as standalone filtration units or as part of a multi-stage filtration system. In some cases, GAC filters are used as pre-filters to remove sediment and larger particles before water passes through finer filtration stages. They can also serve as post-filters to further polish the water and remove any remaining impurities.

Overall, a Granular Activated Carbon (GAC) filter is an effective and versatile solution for improving water quality by removing chlorine, VOCs, odors, and other contaminants from water. It provides an affordable and reliable means of achieving cleaner and better-tasting water for various residential, commercial, and industrial applications.
