Disposal considerations
Comply with local conditions when disposing of the liquid. 320 grams of 50% potassium hydroxide are required for each kg. of
product to obtain a pH of 7-8.
Dispose of contaminated packing by emptying it as much as possible and then rinsing it. Now the packing can be disposed of as
normal household waste or can be collected for recycling.
11.2.9
Quantity of anti-scale product to be used
The pumps that introduce anti-scale product into the wash water have performance values that average around 1.7 ml/second. This
means that 1.7 ml of liquid is diluted in the water for every second of operation.
For example if there are 6 liters of water and the hardness of the water suggests using 1 ml/l concentration then dosage must be
equal to 6 ml of liquid. Consequently the anti-scale pump must be programmed for an operation of approximately (6/1.7=) 4 seconds.
The required concentration depends on the hardness of the water according to the following table:

(French degree)
