Filtering with with granular activated carbon (GAC) is a proven method to remove different impurities from water. GAC is particularly effective in color removal and organic content removal. Aqua Clear Water Treatment Specialists Activated Carbon Filters can be used to remove chemicals that give objectionable odors or tastes to water such as hydrogen sulfide or chlorine.
Aqua Clear Water Treatment Specialists GAC Systems do not remove chemicals such as iron and nitrate because they are not attracted to the carbon. They need to be removed by other types of filtration. Aqua Clear Water Treatment Specialists Commercial Reverse Osmosis (RO) or green sand may be needed. RO membranes will also remove certain organic chemicals.
What is Granular Activated Carbon (GAC)
Granular activated carbon (GAC) is produced from raw organic materials (coconut shell or coal) that are high in carbon. Heat is used to activate the surface area of the carbon. Filters made with carbon are sometimes referred to as charcoal filters. Aqua Clear Water Treatment Specialists activated carbon remove certain chemicals that are dissolved in water by adsorbing the chemical in the GAC.
It is imperative to know the type and concentration of contaminants in order to determine the correct size and components of the Aqua Clear Water Treatment Specialists GAC System. All Aqua Clear Water Treatment Specialists GAC Systems require proper installation and periodic maintenance. As time goes by the strength of the GAC to remove chemicals become exhausted and the GAC needs to be changed. GAC exchange rate is based on contaminant levels and water usage.
