- Transparent cup, 1 litre with marking at 0.5 litre 6.277-001.0

- Dropping bottle with test solution 6.394-426.0

- Plastic eating spoon.

1.

Measure pH-value of water, has to be between 6 and 9

2.

Pour 0.5 Liter raw water into cup

3.

Give 10 drops of flocking test solution into spoon

4.

Fill flocking test solution into cup, at this stir strongly for 5 seconds

5.

Leave cup: flocking has to start within 1 minute and settle significantly.

If no flockung has start repeat test and change quantity of flocking test solution (first
more test solution, if not successful repeat with less test solution).

If analysis is not possible on the spot, take out 2 litres of test solution and store in refrigerator at
ca. 4°C until analysis. Cooling maintains cloudiness by suspended matter.

Shake well before measurement in laboratory.

Adjustment of dosing pump flocking means:

- Stroke: 40%

- Frequency: 70%.

The required amount of flocculation agent RM 5001 is then calculated as follows:

- For 50% yield: number of drops x 120 = ml RM 5001 per 10 litres metering solution

- For 75% yield: number of drops x 80 = ml RM 5001 per 10 litres metering solution

The flocculation test gave 11 drops of flocculation test solution to 500ml up to ideal flocculation,
the yield is 75%:

11 drops x 80 = 880 ml RM 5001 per 10 litres of metering solution
