Water treatment systems contain filters that break down and remove toxins in water lines. Filtering units range from small, single cartridges that treat water for an espresso machine to multi-cartridge systems that filter for large commercial facilities. Chemicals, such as chloramines, chlorine and ammonia can build up as scale and eventually damage equipment. Water treatment systems are used in beverage dispensers, ice machines, coffee brewers, warewashing machines, etc. Not only do water filters stop toxins from entering the body, but they also work to enhance flavors and eliminate bad tastes and odors. It is necessary to replace filtration cartridges regularly bases on water quality. Equipment such as steamers and ice machines should be cleaned thoroughly and sanitized before installing water filtering systems.
