Decades ago, municipalities started adding ammonia to the chlorinated water treatment to boost the effectiveness in making water safe for consumption. As you can see in the chart above, Florida is one of the largest users. Chloramine is a combination of both chlorine and ammonia designed to strengthen the chlorine, making it last longer through the municipal water system. Chloraminated water is blended at the municipal water treatment site. It is monitored daily and after a large amount of rain, it is then blended a little stronger to handle the extra amount of water in the supply. The ammonia in the water has created new types of problems that commercial equipment must deal with. Chloramines damage gaskets and o-rings and react with sweeteners in fountain syrups to form compounds that impact the taste. The activated carbon filters we used in the past are not as effective in removing chloramine as they were with chlorine. So new types of filters and filter systems have been designed to deal with this problem. We constantly recommended the Everpure Series of CLM filters; the EV9278-11, EV9278-12, EV9278-13, and the EV9278-14.
All are not only rated for Chloramine but are NSF 42 and 53 certified. They have also been specified by Coca-Cola after testing with the new Coke Freestyle unit. For even larger capacity applications, the Everpure CB20 series can supply up to 5 gallons per minute for up to 85,000 gallons of water. If you have a chloramine problem, let us know right away.

Confused about which carbon filter to use? Don’t worry! You’re not alone. Here are a few choices when considering which carbon filter to get. Granular Activated Carbon (GAC) cartridges effectively reduce unwanted tastes, odor and chlorine taste & odor from your drinking water. They are designed to allow maximum contact between the water and carbon, ensuring maximum adsorption. The cartridges pictured to the left are the Pentek GAC cartridges. The construction of these cartridges allow water to enter at one end and pass through the entire length of the carbon bed before exiting the other end of the cartridge, while an internal expansion pad minimizes channeling or bypass. Before the water exits the cartridge, a 20-micron post filter helps reduce carbon fines and other suspended particles from the filtered water. The post-filter is permanently fastened to an innovative support basket ensuring that it is firmly secured and eliminating any potential for bypass. GAC Series cartridges are available in a variety of sizes and flow rates, and effectively provide good general-purpose drinking water filtration. Carbon block cartridges are manufactured using a patented process that yields a cartridge with a nominal 5-micron filtration rating, high dirt-holding capacity. A high porosity design helps prevent the cartridge from plugging before its adsorption capacity is exhausted, maximizing the utilization of the carbon while maintaining low pressure drop. The cartridges pictured to the left are Pentek’s EP carbon block filters. They are protected by Endurawrap®, a uniquely formulated polyolefin bilaminate pre-filter, designed to significantly increase the useful life of the cartridge by trapping sediment that typically plugs carbon block cartridges. EP Series cartridges are manufactured entirely from FDA-compliant materials making them an ideal choice for a wide range of residential, food service, commercial and industrial applications. Coconut based carbon block cartridges are highly effective at reducing unwanted taste & odor and chlorine taste & odor from potable drinking water, and they are equally effective at reducing fine sediment. Coconut based carbon block cartridges are manufactured using a patented process and are made from a water-washed, coconut-carbon formulation. This process and media yield a cartridge with high chlorine taste & odor reduction capacity. The cartridges pictured to the left are Pentek’s CEP-10E and the CCBC-10. They are protected by Endurawrap®, a uniquely formulated polyolefin bilaminate pre-filter, designed to significantly increase the useful life of the cartridge by trapping sediment that typically plugs carbon block cartridges. They are an ideal choice for a wide range of residential, food service, commercial and industrial applications. They also make excellent polishing filters or pre-filters in applications requiring fine filtration and high capacity. For more information about which carbon is best for you, call us at 800-942-7873!
