and Function

5.1 Basics

5.1.1 Application of Chlorine

Dioxide in Water Treatment

Properties of chlorine dioxide

❏ Strong and fast oxidizing and disinfecting agent

❏ Wide range of application in drinking-, service-, cooling- and waste water

treatment

❏ chemically instable compound

- can explosively decompose to chlorine and oxygene when being under

pressure, heated or exposed to UV rays

- has to be produced on demand at the place of use

➜

Observe chap. 2.3 (Averting dangers)!

Advantages of chlorine dioxide in comparison to chlorine

❏ Over the whole pH range of drinking water (pH 6.5-9), chlorine dioxide has a

good to very good bactericidal, virucidal and sporicidal effect.

(The disinfecting effect of chlorine is reduced when the pH value rises!)

❏ No forming of haloforms (trihalomethanes) with decomposable water

contents

❏ No forming of chloramines with ammonia or aminocompounds

❏ Strongly reduced formation potential of higher-molecular organic halogene

compounds

❏ Good stability in water

- suitable bactericidal and bacteriostatic protection of water networks.

5.3 Course of Function

❏ For preparing a chlorine dioxide solution, four components are necessary:

- Chlorine gas

- Solution water

- Sodium chlorite

- Dilution water

The amounts of these components are determined by the preparation

method and may therefore not be changed. The flow rates of the single

components are monitored by rotameters.

❏ In the injector, the chlorine gas is mixed with the solution water and flows

into the reactor.

❏ The sodium chlorite is also being dosed into the reactor.

❏ In the reactor, the reaction of chlorine solution and sodium chlorite takes

place, forming chlorine dioxide.

❏ The solution formed in the reactor flows into the solution tank and is being

mixed with the dilution water. This produces a ready-to-use chlorine dioxide

solution.

❏ The ready-to-use solution can now being withdrawn from the solution tank.

❏ The extraction injector continuously sucks residual chlorine gas out of the

reactor and leads it to a carbon filter.

❏ The solution tank is equipped with level sensors.

In automatic operation, the system is

- switched on when the min. level is reached.

- switched off when the max. level is reached.

- switched off if at least one of the component's flows is out of the

permissible limits. This switching-off takes place after a time delay.
