“Chlorine Definitions“
„Effective chlorine“ (total chlorine)
The sum of the elementary chlorine (free effective chlorine), available in the water at
the point of time of analysis and its sterilizing acting compounds (bound effective
chlorine) is called „effective chlorine“ (total chlorine).
„Free effective chlorine“
Chlorine, which is available in a water in form of dissolved elementary chlorine (free
chlorine), hypochlorous acid or hypochlorid ions, is called as „free effective
chlorine“.
„Bound effective chlorine“
Chlorine, which is available in a water in form of oxidizing acting chlorine substitution
compounds (anorganic and organic chloramines) is called as „bound effective
chlorine“.
Calculation as follows:
total chlorine
-free effective chlorine
= bound effective chlorine

IV 1.5. Controls during operation
All units operated with fuel must be checked at regular intervals on fuel and oil level
during operation, so that a perfect operation is guaranteed. If the precoat pump
would fail due to a leakage of fuel, the complete backwashing and precoating
process would have to be repeated.
The same situation would occur with the electrical pumps. The current generators
have to be checked continuously.
