Directions for use
Evaporator Defoamer is used in conjunction with Vaptreat antiscalant when foaming problems occur in the evaporator. Foaming problems can occur with certain design of evaporators and under certain conditions like elevated sea water temperature. Evaporator Defoamer is used to combat such problems and prevent foaming and carry-over. Vaptreat is formulated with a defoamer in the product, however under certain conditions additional defoamer is required to maintain maximum operating efficiency of the plant.
Dosing Instructions
The standard dosage is 1% of the descalant dose.
for example, if the daily consumption of Vaptreat is 10 L, the recommended dose of Evaporator Defoamer is 0.1L. The maximum dosage of defoamer should not exceed 1 PPM based on rated output of the evaporator.
Dosing Method
Evaporator Defoamer has limited solubility in water. The best dosing method is to mix the product with the antiscalant and water in a dosing tank. The amount of defoamer in the mixture should not exceed 1% of the water added.
