Sponge iron products for industrial circulating cooling water

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

Sponge iron is suitable for replenishing water boilers.

Low pressure steam boiler feed water.

Industrial circulating cooling water replenishment

Oilfield water injection.
