Stanrose® Vaptreat

Stanrose® Vaptreat is a concentrated liquid blend of polymer and antifoam agents for controlling scale and foam in evaporators. Stanrose® Vaptreat is Approved by the Norwegian National Institute of Public Health for application in evaporator systems that are used to produce potable water.

Common Name

Vapour Treatment

Product Code

STAN-SSC209

Features and Benefits

Stanrose® Vaptreat prevents scale by crystal distortion, dispersion, and absorption of scale forming minerals. Crystal distortion
As soluble minerals are forced out of solution during evaporation hey go through an intermediate crystal stage before forming dense deposits.
Stanrose® Vaptreat reacts with the crystals causing them to be distorted and irregularly shaped. The distorted crystals do not form dense and uniform deposits which would adhere to evaporator surfaces.
Ensures that the evaporator works at maximum efficiency by keeping heat transfer surfaces free of scale
The antifoaming properties ensure that distillate quality is high as carry over is eliminated
Will gradually remove existing scale when dosed at twice the normal rate
Concentrated, safe liquid, easy and economical dosing

Technical Properties

Appearance pale yellow liquid
Flash Point none
PH of 1% solution 9.2
Specific Gravity 1.09

Recommended Uses

Stanrose® Vaptreat should be fed continuously to the evaporator inlet line. Stanrose® Vaptreat can be diluted with fresh water and the feed solution introduced with an eductor or an positive displacement metering ppm.

Method of Application

The specially selected polymers in Stanrose® Vaptreat combined with the potential scale forming salts in the brine to prevent them from adhering to heat transfer surfaces. These solids are held in suspension and removed with the evaporator brine.
The operating efficiency of the plant is maintained for maximum water production. The intervals between cleaning are greatly increased.
The product to use for acid cleaning is Stanrose® Descaler, which will remove old scale prior to treatment with Stanrose® Vaptreat .
Evaporators have a tendency to produce foam while operating - the de-foaming properties of Stanrose® Vaptreat will stop this foaming and carry-over will be eliminated. Distilled water quality is maintained.
Dosing Method
The standard dosage, applicable to the majority of systems, is 15-30 ml of Stanrose® 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 Stanrose® 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 Stanrose® 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 Stanrose® 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 Stanrose® 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.
Dosage :
The recommended dosage rate for Stanrose® Vaptreat is 5 to 10 ppm based on type, usage and operating conditions of the evaporator. Your Stanrose® service engineer will readily guide you on the correct dosage. It is preferred that the evaporator be clean and free of deposits before Stanrose® Vaptreat is introduced .
Stanrose® Vaptreat will clean up moderate amount of existing deposits. Double the dosage rates previously recommended during the clean up period.

Storage and Handling

No special precautions required. Use the same care as in handling other chemicals used for maintenance.
Store in a dry place, keep container closed when not in use. Avoid contact with skin. Wash with large quantities of water.
In case of contact with eyes, treat with large volumes of water and see a physician.
Avoid contact with eyes and skin. In case of contact rinse with plenty of water. Wear suitable protective clothing, gloves and eye/face protection.
Keep away from heat, sparks and open flame. Ensure that the working area is well ventilated.
Store at moderate temperatures in dry, well-ventilated area.
