Granular Activated Carbon (GAC) Filter

Granular Activated Carbon (GAC) Filter

Activated carbon works via a process called adsorption, wherein a highly porous pattern in the granulated carbon media adsorbs and entraps contaminants from the water. The contaminant particle is diffused into a pore and become adsorbed. The higher the contaminant concentrations the greater the removal capacity of the activated carbon, however, it may require longer contact time with the media.

The same operation principle as the Multimedia Filter is applied to Activated Carbon Filter. Water flows from the top of the vessel passing through the activated carbon bed, treated water is collected from the bottom and backwash is initiated once the pressure drop increased or the efficiency of the filter declines.

Applications

Another element is added to the filtration process using activated carbon, in granular form, as a filter media. GAC filtration is very effective in eliminating impurities and contaminants causing bad taste and foul odors, sediments, chlorine other organic compounds.

GAC Filters are commonly used for water purification, air filtering and other industrial gas processing:

  • Drinking water
  • Condensate water treatment
  • Applied after multimedia filter to protect RO membranes from chlorine
  • Industrial water treatment
  • Polishing filter for iron removal
  • VOCs & H2S gas removal
