Chlorine removal

Carbon is generally used to remove chlorine form water supplies.  Many of our systems incorporate carbon into their designs, and chlorine injection systems are frequently used in conjunction with an automatic backwashing carbon filter to remove the injected chlorine.  Carbon has a very high holding capacity for chlorine & chloramines – making it both an affordable and practical method of chloride removal.  If you are supplied with municipal water, and your city is using chloramines rather then more traditional treatment with chlorine, then you may want to consider a larger backwashing carbon filter as described below.  Chloramines require more contact time to be effectively removed from the water, and our smaller cartridge based filter may not perform effectively at higher flow rates.  A larger backwashing carbon filter can provide the longer contact times required for better chloramine removal.

Backwashing carbon filter (low levels of H2S)
An automatic backwashing carbon filter will provide good service for taste and odor removal.  However, a carbon filter is only suitable for removing a mild sulfur odor.  Carbon filters require that the filter media be replaced every two to three years (depending on the level of sulfur in your water) at a cost of approximately $100 to $150.  If you feel that you have higher levels of sulfur in your water, you should consider one of the below  solutions, as changing carbon filter media too frequently will be cost prohibitive.

Cartridge based sediment pre-filter
Another method to remove chlorides from water is with use of a cartridge based  whole-house filter.  Our carbon cartridge filter system use a “radial” (RFC) flow design, providing lower pressure drop when compared to GAC (granular activate carbon) cartridge filters.  The RFC cartridge will also filter sediment and provide improved taste and odor control.  For ¾” piping applications consider the a 20”x 2.5” diameter RFC cartridge set.  For larger flow 1” or 1 ¼” piping applications, go with the 10” length x 4” diameter RFC cartridge filter set.  Cartridge are provided in set of three, and typical cartridge filter replacement is every 4 months (a set of three cartridges is normally a one year supply).  See our Cartridge Water Filter page for more information.
