Product Description

SLOW PHOS products are a form of slowly soluble poly-phosphate available in small, glassy beads. As their name implies, SLOW PHOS products are engineered to dissolve at a controlled concentration to prevent scale and formation corrosion.


  • Scale Prevention - Used to sequester hardness, inhibit precipitation, and formation of deposits
  • Corrosion Inhibition - Used to form a protective coating on metal surfaces and provide corrosion protection against acidity, alkalinity, and many other mineral salts which may lead to the "rusting out" of water system pipes and equipment
  • Iron Control - Used to sequester dissolved iron up to 10 ppm and prevent the iron from precipitating, staining, discoloring, and distasteful odor
  • Convenience - Offers operator convenience in feeding; only requiring addition of the product at monthly or quarterly intervals; expensive proportioning and feeding equipment is not required


SLOW PHOS can be fed at different concentrations in order to fit particular treatment situations or requirements. Normally a concentration of SLOW PHOS at threshold levels of 0.5-5.0 ppm poly-phosphate will inhibit scale and corrosion.
