elements.

1.10 Chemicals

1.10.1 Chlorine dioxide concentration
In the reaction tank of the disinfection system, diluted sodium
chlorite and diluted hydrochloric acid are mixed to create a
chlorine dioxide concentration of approximately 20 g per litre of
water. The chlorine dioxide solution is diluted again, and dosed
into the main line to be disinfected, according to the
requirements. According to the German drinking water ordinance
(TrinkwV 2001), the chlorine dioxide concentration in drinking
water must not exceed a maximum of 0.4 mg per litre of water.
The following safety instructions must be observed:
Warning

may result in serious damage to the equipment and
personal injury.
It is forbidden to dismantle, modify, change the
structure of, bridge, remove, bypass or disable
components, including safety equipment.
Warning
Risk of explosion when using chemicals in too high a
concentration.
Only use sodium chlorite in a diluted concentration of
7.5 % by weight in accordance with DIN EN 938.
Only use hydrochloric acid in a diluted concentration
of 9.0 % by weight in accordance with DIN EN 939.
The safety data sheets from the supplier must be
observed.
Warning
Risk of explosion and serious damage to equipment
and personal injury as a result of operating faults due
to confusing the chemical containers or suction lines.
Do not confuse the containers.
Observe the red and blue markings on chemical
pumps, suction lines and chemical containers: Red =
HCl, blue = NaClO .
