Knowtech, Inc. manufactures a full line of ion exchange systems using cation (a negatively charged ion) / anion (a positively charged ion) exchange resins for a wide variety of water treatment applications. Our systems are also efficient in reducing toxic metals, radium reduction, unwanted color, perchlorates, and DBP precursors.

What does ion exchange remove?
  • Hardness removal (water softener)
  • Nitrates
  • Alkalinity
  • Chloride removal
  • Sulfates
  • Fluorides
  • Organics reduction
  • Silica removal
  • Perchlorate
  • Radium and Uranium removal
  • Arsenic removal
  • Barium removal
  • Boron removal
  • TDS reduction

All Knowtech ion exchange systems incorporate the latest resin technology utilizing the highest quality resins furnished by well-known manufacturers. Our unique Regenerate Distribution System accomplishes complete and uniformed regeneration of the resin. The ion exchange water treatment systems also include state of the art PLC based or digital stager regeneration controls to assure consistency and reliability.
Knowtech, Inc. designs and manufactures both standard and specially engineered ion exchange water filter equipment for an array of applications including deionization (separate and mixed bed), alkalizes, nitrate removal from water (NO3), and condensate polishers.

Advantages of Ion exchange water treatment systems
  • Fast results
  • Short and long-term applications
  • Variety of tank sizes.
  • Allows for quick installations.
  • Requires minimal maintenance

What are ions in the water?
Ions are electrically charged molecules and are formed as pollutants dissolve in water. Natural areas of water have a balance of positively and negatively charged ions. Ions are what determine the TDS and conductivity of the water. The greater presence of ions results in higher TDS and conductivity.

How does ion exchange water treatment work?
Ion exchange water treatment works by removing material from the water through the use of water processes such as water softening systems, and water deionization systems. These systems work by exchanging specific ions for other ions. When it comes to water softeners, magnesium and calcium ions are replaced by sodium ions. As for water deionization systems, the cations are exchanged for hydrogen ions, while the anions are exchanged for hydroxyl ions.
