Mixing Chlorine, Flocculation Agent and Antiscalant
3.2.1
First fill of the metering tanks
The first time they are filled, the metering tanks are filled with 30 litres of chlorine-free water.
This is taking from the reverse osmosis at the drinking water sampling tap (1/12).
For the first fill of the metering tank, the system is switched to disinfection mode and set to the
following flow rates:
- Drinking water: 100 l/h
- Concentrate: 600 l/h
During the disinfection operating mode, all confirmation queries are switched off!
Observe the pressure downstream of the fine filer: as soon as it is less than 2 bar
pressure, immediately switch off the system. The high-pressure pump is running dry!
Use the prescribed system yield (50% or 75%) and the water analysis to determine each of the
chemical quantities for a 30 litre metering solution according to Chap. 3.2 to 3.5, add to the tanks
and mix well.
Switch the system to operation mode.
3.2.2 Pre-chlorination
Only use drinking water to dilute the original chlorine product upstream of the
chlorination point. This water is taken from the drinking water tap (1/4.21).
1. Take the system yield (50% or 75%) from the evaluation of the untreated water analysis.
2. Take the analysis values for iron (Fe), manganese (Mn) and ammonium (NH3 or NH4 ) in mg/l
from the untreated water analysis.
3. Iron content:
____ x 0,4 = ______
Manganese content:
____ x 0,6 = ______
Ammonium content:
____ x 8,0 = ______
Basic requirement:
1,2
Total:
==========
4. For 50% yield:
Total x 192 = ____ ml RM 852 per 10 litre metering solution
OR
Total x 51
2
= ____ ml calcium hypochlorite (1ml corresponds to 1.05g) per 10 litres metering solution
