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) |
Example: 75 litres ready mixed metering solution (one metering tank) consists of 7.5 x 32 = 240 ml RM 852 or 7.5 x 17 = 128ml (=136 g) calcium hypochlorite and
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 |
3.2.5Flocculation Agent
The exact demand in flocculents can only be determined by test. Therefore a test solution is mixed first, then the raw water is flocked and finally the dosing quantity is evaluated.
3.2.5.1Mixing of the flocking test solution
Auxiliaries:
-Measuring cup with
-Desalinated water (refill water for car batteries)
-Flocculent RM 5001
-Measuring cup 25 ml
-Dropping bottle 50 ml,PE
-Plastic eating spoon.
Work Steps:
1.Give 25 ml flocculent RM 5001 into measuring cup
2.Fill up with desalinated water to 500 ml
3.Stir up thoroughly with plastic eating spoon
4.Give 50 ml of this into a clean dropping bottle, close bottle
