Sponge iron deoxidizer

Sponge iron deoxidizer has good reduction activities, and the characteristics of the high specific surface area, as water deoxidizer sponge granularity for 2-5 mm, high porosity, specific surface area, high activity, easy to react with the oxygen in the water to generate Fe3O3, to reach deaerating purpose, flocks of reaction product is not easy to dissolve in water, be stopped, with a certain intensity backwashing water can rinse clean.

Sponge iron deoxidant belonging interesting filter type oxygen, the nature of the chemical oxygen, it is specializing in the production of sponge iron deoxidant to remove dissolved oxygen in water, the internal structure of the porous, provides the specific surface area of 5-100000 times that of ordinary iron filings, can make the water of oxygen and iron occurs rapidly radical oxidation reaction, the dissolved oxygen stable under 0.05 mg/L, the following equation: fe2 + + 2 h2o + O2 2 Fe (OH) 2, 4 Fe (OH) 2 + 2 h2o + O2 4 Fe (OH) 3 reaction product Fe (OH) 2Fe(OH)3 is a flocculent precipitate that is not easily soluble in water. It is intercepted as the water flows through the remaining sponge iron particles, and can be washed clean with a certain strength of backwash water (about 5 minutes).

Sponge iron deoxidizer consumption is very low, according to the treatment of water and water quality, generally 3-6 months can be supplemented once.
