MCT 501C Portable and Process Water Treatment, Unique Blend of Linear Chain Phosphates

MCT 501C Potable and Process Water Treatment is a specially engineered phosphate blend that is used for water system stabilization. MCT 501C sequesters soluble iron, manganese, calcium and magnesium and eliminates the red water problems associated with water systems. MCT 501C also controls or eliminates corrosion and scaling problems and provides the added advantage of slowly removing accumulated soft deposits that tend to restrict or reduce water flow.

MCT 501C is typically used by:

  • Municipal Water Systems
  • Independent Water Systems
  • Institutions
  • Hospitals
  • Industry
  • Private Water Systems

MCT 501C is composed of ingredients certified by NSF for potable water treatment application. MCT 501C is approved to 25 ppm in the system.

Directions for Use:

MCT 501C is a liquid product and should be fed proportional to water flow. Typical dosages range from 1.0-5.0 ppm phosphate by the orthophosphate test procedure. An initial starting dosage of approximately 6 – 7 gallons MCT 501C per million gallons of system water is recommended. Increase or decrease dosage depending on severity of systems conditions. Test kit code 3114 for orthophosphate is recommended.
