MCT 504 Potable Water Stabilization

MCT 504 potable and process water treatment is a specially engineered phosphate blend used for water system stabilization. This product is composed of a linear chain poly phosphate that minimizes or controls metal corrosion and scale formation in potable water systems. MCT 504 sequesters soluble iron, manganese, calcium and magnesium and eliminates the red water problems associated with system corrosion and raw water iron. Lead and copper residuals from system leaching is also minimized.

MCT 504 is composed of ingredients that are accepted by the National Sanitation Foundation (NSF) for use in potable water supplies. MCT 504 is approved for maximum use to 23 mg/L in the system. Also, the raw materials are recognized as safe (GRAS) according to the provisions in the code of Federal Register, Section 182, Title 21.

Directions for Use:

MCT 504 should be fed proportional to water flow. An initial starting dosage of approximately 4.5-5.5 gallons of MCT 504 per million gallons of system water is recommended. Typical dosage residuals range for 1-4 ppm phosphate by the orthophosphate test procedure. Increase or decrease dosage depending on severity of system conditions. Test kit code 3114 for orthophosphate is recommended.
