rohm and haas ion exchange ion exchange introduction 1 fd sep 2008 ion exchange for dummies an introduction water water is a liquid. water is made of water molecules (formula h2o). all natural waters contain some foreign substances usually in small amounts.
this information is required to calculate the exchange capacity of the anion resin. depending on the regeneration method & the ratio of alkalinity ions to the total anion load the capacity can range from 5000 to 12000 grains of alkalinity removal per cubic foot of resin.

cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons and a nonmetal gains those electrons. the electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound such as sodium chloride. a metal reacts with a nonmetal to form an ionic bond.
the two types of ion exchange units are water softeners and anion exchange devices. water softeners remove cations (positively charged ions such as calcium and magnesium) and replace them with sodium. anion exchange devices remove anions (negatively charged ions such as arsenic and nitrate) and replace them with chloride.
