CAPACITY CALCULATION
The volume of mains water that a tank can demineralize is calculated based on the basic capacity of the tank.
Flash presentation >>
The tank capacity is calculated by dividing the total salt content of the saline water converted into °GH into the basic capacity.
Example:
SILEX 21 has a basic capacity of 22,700 litres °GH.
The total salt content of the water corresponds to 20°GH.
Calculated capacity:
22,700 divided by 20 = 1,135 litres.
N.B.: If the plant is to polish demineralized water to obtain the lowest possible conductivity and silica content, the capacity must be calculated by one of our technicians.
