SEQUEST-ALL® EMC Granular Water Treatment


Sequest-All® EMC is a proprietary blend of various high quality domestically (US) produced potassium phosphates, polyphosphates and stabilizers specifically formulated to maximize the sequestration of natural mineral ions especially iron, manganese. Sequest-All® EMC granular is designed to successfully treat potable and non-potable water systems to furnish the following system benefits. Sequest-All® EMC granular is uniquely designed to function effectively at high water temperatures and extended performance life.

SEQUEST-ALL® EMC Granular Functions:

  • Our most specifically designed mineral sequesterant of naturally occurring minerals (such as iron, manganese, calcium, etc.) found in potable and irrigation water sources. Sequest-All® EMC minimizes the potential for rusty and/or dirty water though out 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.
  • Sequest-All® EMC is also a very effective deflocculant that breaks up aggregates into fine particles. This function helps to remove particles from surfaces to provide a cleansing action throughout the water system. It is an ideal treatment to use in Industrial cleaning operations
  • Reduce the demand for chlorine because of the stabilization of minerals and reduction of scale deposits – effectively improving disinfection throughout the water distribution systemwhile providing effective corrosion inhibition.
  • 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® EMC is 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® EMC Granular Application & Dosage

Sequest-All® EMC blended potassium phosphate can be applied to a water system by a chemical injection metering pump once liquified with water. Sequest-All® EMC 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® EMC remains completely dissolved and clear throughout in your solution tank.
