Material Safety Data Sheet





ALKEN® TREATMENT 63 is a blend of selected phosphates which react to precipitate the calcium hardness in the boiler as a sludge and prevent calcium carbonate, sulfate and/or silica deposits. This formula contains silica to assure precipitation of magnesium as a fluid sludge. The finely divided non-adherent calcium phosphate and magnesium silicate sludge remains suspended in the boiler water until removed via the blowdown. ALKEN® TREATMENT 63 contains the best and most highly concentrated phosphates to assure maximum results with a minimum of treatment.



  • Prevents calcium scale deposits.
  • Forms nonadherent sludge.
  • Cost-effective. A phosphate precipitation program can be the most economical where significant hardness levels exist in the feedwater.
  • Clear and easy dosage control.


ALKEN® TREATMENT 63 dosages depend upon many factors including the chemical characteristics of the makeup water, boiler operations, percentage of condensate return, etc. Approximate requirements can be estimated as ¾ pound of treatment per pound of hardness entering the boiler. Individual dosage recommendations are made for each installation by your ALKEN® representative, based on his survey. Dosage is controlled by a simple color comparison test.


ALKEN® TREATMENT 63 is compatible with most boiler water chemicals and can be blended with them in the treatment feed tank. ALKEN® TREATMENT 63 may be fed in a number of ways depending upon the makeup water characteristics and the boiler operations. Specific recommendations will be made by your ALKEN® representative for each installation.


Store ALKEN® TREATMENT 63 in cool dry place. Store in a tightly closed container at moderate temperature, do not freeze.. Wash thoroughly after handling. Use only in a well ventilated area. Avoid contact with skin, eyes, and clothing. Do not inhale or ingest. Consult current Material Safety Data Sheet for handling and storage precautions


ALKEN® TREATMENT 63 is packaged in LDPE lined fiber drums, which conform to Performance Oriented Packaging Specification. ALKEN® TREATMENT 62 is shipped in the following sizes: 100 lbs. (13 gallon drum) and 300 lbs. (35 gallon drum).

Update: 02-19-2007
