3.2.4Metering Amounts and Mixing of the Post Chlorination

The chlorine quantity given matches a chlorine content of 0.3mg/l in the drinking water.

The following quantities of RM 852 or calcium hypochlorite are each required for 10 litres of metering solution:

-

RM 852 Sterilization Agent:

32 ml

-

Chlorinated Lime:

17 ml (= 18 g)

The quantities must be adjusted accordingly for higher or lower chlorine contents.

Example: Chlorine content: 1.2 mg/l

-

RM 852:

4 x 32 ml = 128 ml

-

Chlorinated Lime:

4 x 17 = 68 ml
