The standard dosage, applicable to the majority of systems, is 15-30 ml of Vaptreat per ton of distillate produced. This is based on the rated production capacity of the evaporator.
Example: In a 25 ton/day evaporator. Treatment used = 25 x 30 ml = 750 ml of Vaptreat per day.
Setting the Flow Rate
The treatment is added to the dosage tank and mixed with water. Example: With the 0.75 litres of Vaptreat add sufficient water to make up 50 litres of liquid.
Flow rate calculation:
Flowrate = 50 Litres/24 x 60= 35 ml/min setting
This will last 24 hours.
A metering pump can also be supplied for use with Vaptreat if required.
N.B. The brine density should not exceed 1.038 g/cm3. The scaling potential increases rapidly over this level. An increase in the amount of Vaptreat used will assist in retaining potential scale forming salts in suspension.
For example:
If the density rises to 1.050 g/cm3 the dosage should be 60 ml/ton of rated capacity.
