Sponge iron granular for hot water boiler

Product: Sponge iron

Color: Black/ blue

Usage: Boiler / water treatment

Packing: 25 kg/bag or ton bag


Sponge iron is also called direct reduced iron. It uses high-quality ore and for the principle of redox reaction to remove it by filtration. It can remove corrode dissolved oxygen in pipelines, boilers and circulating water. The dissolved oxygen content can reach 0.05 mg / L or less.

Advantage of Sponge Iron

  • Low backwash frequency
  • High compressive strength
  • Large surface area
  • High activity
  • Good regeneration effect

Application of Sponge Iron

  • Hot water boiler
  • Sponge iron is suitable for replenishing water boilers.
  • Low pressure steam boiler feed water.
  • Industrial circulating cooling water replenishment
  • Oilfield water
  • Counterweight/anti-corrosion
