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.

Calculation of total salt content of the inlet water, converted into °GH

 Cation load °GH. Calculation °GH Calcium Ca2+ mg/l x 0,140 = Magnesium Mg2+ mg/l x 0,230 = Sodium Na+ mg/l x 0,122 = Ammonium NH4+ mg/l x 0,156 = Anion load Chloride Cl- mg/l x 0,079 = Sulphate SO42- mg/l x 0,058 = Bicarbonate HCO3- mg/l x 0,046 = Nitrate NO3- mg/l x 0,045 = Silicic Acid SiO3 mg/l x 0,047 = Uncombinex Carbonic Acid CO2 mg/l x 0,064 = The total salt content – German degree °GH
