Twin Bed Deionization CartridgesAries FilterWorks twin bed deionizaton cartridges use ResinTech® cation and anion resins in a two bed, layered cartridge. These resins, combined with the cartridge manufacturing of Aries FilterWorks, provide consistent water quality with the backing of a strict quality control program. Standard Twin Bed and High Capacity configurations are available depending on the effluent range required.About Twin Bed DeionizationHigh purity mixed bed cartridges removal all minerals and can be very corrosive to materials such as copper, aluminum, and certain types of stainless steel. Layered cartridges are an ideal alternative to mixed bed cartridges providing moderate ionic removal without the corrosive characteristics. Standard twin bed cartridges use a layer of strong acid cation (SAC) and strong base anion (SBA) resin. “High Capacity” twin bed cartridges are made up of strong acid cation (SAC) and weak base anion (WBA) resins. Using these resins provide lower grade water compared to the standard twin beds as the weak base resin ignores carbon dioxide and silica ions yielding more capacity. Using premium ResinTech® resins ensures consistent quality and performance.
