UVU is very different from most universities as we do not teach from a textbook. Most instructors have a PhD in engineering and 20-40 years of experience. Course content is developed from scratch and is based on the instructorâs experience. The textbook serves as a reference and some reading assignments are made.
Deionization (DI Water or Demineralization) simply means the removal of ions. Ions are electrically charged atoms or molecules found in water that have either a net negative or positive charge.
The ion exchange technology is used for different water treatment applications: 1  Softening (removal of hardness). 2  De-alkalisation (removal of bicarbonate). 3  Decationisation (removal of all cations). 4  Demineralisation (removal of all ions). 5  Mixed bed polishing.6  Nitrate removal. 7  Selective removal of various contaminants.he ion exchange technology is used for different water treatment applications: 1  Softening (removal of hardness). 2  De-alkalisation (removal of bicarbonate). 3  Decationisation (removal of all cations). 4  Demineralisation (removal of all ions). 5  Mixed bed polishing. 6  Nitrate removal.
