History of Deionizers

Basics of Deionization by Ion Exchange

THE PAST:

In the early 1800s, several scientists discovered the ion exchange process. The ion exchange industry in the United States was born in the early 1900s when cation exchangers were first synthesized.

ALL NATURALLY-OCCURRING WATER:

All naturally-occurring water contains dissolved mineral salts. In solution, salts separate into positively-charged cations and negatively-charged anions. Deionization can reduce the amount of these ions to a very low level through the process of ion exchange.

OUR UNITS PRODUCE LABORATORY GRADE DEIONIZED WATER:

Our units produce laboratory grade deionized water used in everything from auto detailing and manufacturing to kidney dialysis. Deionization is a method used by laboratories to produce purified water. The definition of pure is the "removal of ions," and the term is generally used with respect to the removal of ions from water. Deionization is commonly achieved by passing the water through successive ion exchange columns. In one column, ions are exchanged for H+ ions. In another column, anions are exchanged for OH- ions. Following a reaction of H+ with OH- ions, no ions remain in solution. This is produced through ion exchange. Simply said, water flows over porous beads that are positively and negatively charged, and the minerals (or total dissolved solids) are removed. These ion exchange columns are porous beads called exchange resins.
