Sponge iron is also called direct reduced iron. It uses high-quality ore and uses the principle of redox reaction to remove it by filtration. It can corrode dissolved oxygen in pipelines, boilers and circulating water. The dissolved oxygen content can reach 0.05mg / L or less.
Suitable for hot water boiler
Feedwater for low pressure steam boilers
Suitable for industrial circulating cooling water replenishment
Suitable for oilfield water injection
Features of sponge iron
Sponge iron has low backwash frequency, high compressive strength, no chalking, no compaction, and large specific surface area. High activity and good regeneration effect.
