Stanrose® Fostreat BWT
Stanrose® Fostreat BWT is a dry powdered phosphate based treatment used to precipitate calcium hardness as a non adherent sludge. Stanrose® Fostreat BWT is a free-flowing white powder which is readily soluble in water. When Stanrose® Fostreat BWT is added to the boiler water under proper conditions it supplies the necessary phosphate to chemically react with calcium hardness to prevent the formation calcium carbonate, sulphate and/or silicate scales. The reaction between calcium and phosphate produces a finely divided non adherent sludge (calcium phosphate) which remains suspended in the boiler water and removed through blowdown.
Features and Benefits
Scale problems eliminated. Sludge problems greatly reduced.
Easily dissolves in water to prepare feed solutions.
100 % active material.
Dry product minimizes shipping cost.
Feed solutions up to one pound per gallon possible.
Dosage Chart :
1. Find your boiler operating pressure on left.
2. Find your phosphate test results as ppm PO4 across the top.
3. Read across from your operating pressure until you reach the column with your ppm PO4 results. This square will give
you the correct dosage of Stanrose®
Fostreat BWT to reach the correct protection for your boiler.
Dosage table in grams/ton is described in technical data sheet.
Stanrose® Fostreat BWT is used in controlled amount so as to maintain a free phosphate residual in the boiler water. The control limits for phosphate normally are in the 20 to 60 ppm range. Exact parameters will be sent by our representative for your installation. The feed rate for Stanrose® Fostreat BWT will vary depending upon the calcium hardness of the make up water.
Method of Application
Dissolve in warm water and slug feed intermittently to the boiler feed water line or with a continuous feed pump to the boiler. Fostreat can be mixed with other treatment chemicals used for internal treatment. Material of construction of the feed equipment are not critical, but dissimilar metals should be avoided.
Storage and Handling
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.
