Ion Exchange
Ion Exchange

Ion exchange is a chemical process applied in water treatment systems that need removal of ionic pollutants, using solid polymeric ion exchange resins. There are two major types of ion exchange resins — cationic resins, which remove positively-charged ions from water, and anionic resins, which remove negatively-charged ions. In some particular applications, chelating resins are used to remove specific pollutants like metal ions present in water from a semiconductor or metallurgical industry.

Preventing Biofouling on Ion Exchange Resins

How do you avoid biofouling on your ion exchange resins?

In water softening applications, ion exchange resins are put through extreme variations in pH during the regeneration process that normally inhibits biofouling. Most problems with biofouling occur because of improper... (More)

What are Ion Exchange Resins and how do they work?

Ion exchange resins are insoluble, porous, solid substances that enable the ion exchange process. They are typically granular, although they can also be produced as a membrane sheet.

Granular resins normally come as tiny spherical beads made of polystyrene that... (More)
