About Twin Bed Deionization 
High 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.
