Activated Carbon (AC) Filters -
Activated carbon filtration is most effective in removing organic contaminants from water. Because organic chemicals are often responsible for taste, odour and colour problems, activated carbon filtration can generally be used to improve aesthetically objectionable water that is treated to attract certain contaminants. When water passes through this type of filter, the carbon particles attract and remove contaminants (including dissolved substances such as hydrogen sulphide, heavy metals such as lead, mercury and copper and chlorine).
There are two types of activated carbon filters - Granular and Solid Block:
- Granular activated carbon (GAC) filters use a cartridge packed with granules of activated carbon. When water passes through the filter, the filter's numerous carbon granules trap particles and remove substances dissolved in the water (such as chlorine, heavy metals and harmful organic compounds).
- Solid-Block Activated Carbon filters have activated carbon not in the form of small granules, but instead is composed of activated carbon particles that have been compressed into a dense material through which water travels. With very small pores and a larger surface area for the carbon to absorb particles, there is a better chance of trapping contaminants such as pesticides, chlorine, lead and asbestos than there is with other filters.
Whole house tank-type units containing granular activated carbon provide chlorine-free water at spigots. Single faucet devices, often installed under the sink at the kitchen tap, can provide chlorine-free water for drinking and cooking.Ask one of our certified water treatment specialists about our many carbon filter choices and which one is right for you.
