4.2 Chlorine dioxide (ClO
2
) in water treatment
Chlorine dioxide is a potent, fast-acting oxidizing and disinfectant agent,
with the following properties:
n
A good effect against bacteria, viruses, spores and algae
n
Full disinfecting power across a broad pH range (5 – 11)
n
A higher disinfecting power than chlorine
n
The odour and taste threshold of ClO
2
is higher than chlorine
n
Its use does not produce any trihalomethanes (THM) or chloramines
n
ClO
2
has a better repository effect than chlorine
4.2.1 The applications of chlorine dioxide
n
Process water treatment
n
Raw water treatment
n
Legionella prevention
n
Emergency chlorinating systems
n
Water works
n
Breweries
n
Beverage manufacturer
n
Treating food
n
Controlling bio films as on e.g. cooling water systems
4.2.2 The preparation of chlorine dioxide
EASYZON produces chlorine dioxide via the acid-chlorite method using
diluted chemicals. Both chemicals are mixed with water in a reactor and
react to produce chlorine dioxide.
