SEQUEST-ALL® Granular Functions:

  • Control the naturally existing minerals (such as iron, manganese, calcium, etc.) found in potable water sources – minimizing the potential for rusty and/or dirty water thoughout the water system.
  • Reduce mineral scale buildup (by sequestration / chelation and dispersion) on the interior surface of the water distribution system – decreasing tuberculation while increasing the carrying capacity of the system.
  • Maintain water clarity through sequestration and mineral scale control, resulting in fewer customer complaints and reduced flushing requirements.
  • Inhibit corrosion of steel distribution water lines along with iron and galvanized pipes and residential copper and lead plumbing.
  • Inhibiting lead and copper leaching by forming a protective coating on the interior surface of the pipe effectively lowering lead and copper levels making it an ideal treatment for the Lead and Copper rule.
  • Reduce the demand for chlorine because of the stabilization of minerals and reduction of scale deposits effectively improving disinfection throughout the water distribution system.
  • Gradual removal of exisiting mineral deposits, along with continual inhibition of existing natural minerals within the water system from developing scale deposits formations in hot water lines and residential water heaters.
  • Since Sequest-All® WSF-20 & WSF-36 are formulated with highly stable ingredients, the treatment remains effective over longer periods of time at at higher temperature water than standard phosphate treatments.

SEQUEST-ALL® Granular Application & Dosage:

Sequest-All blended phosphate can be applied to a water system by a chemical injection metering pump once liquified with water. Sequest-All goes easily into solution with agitation in concentrations of up to 5 lbs per gallons of water. Typical potable water treatment dosages range from 0.75 to 3.75 mg/L and higher for non-potable systems. Sequest-All remains completely dissolved and clear throughout.
