Sponge iron filter material

Sponge iron filter material (also known as sponge iron deoxidizer) is made of high quality mineral powder, using the REDOX reaction principle, through out in the form of a filter in addition to the lake for pipe, boiler circulating water dissolved oxygen corrosion after dealing with the water dissolved oxygen content can be up to 0.05 mg/L, the deoxidizer has the backwashing frequency is low, high compressive strength, not pulverization, not knot board, specific surface area. The advantages of high activity, the regeneration effect is good.

Sponge iron filter material-WADE

After activation treatment of sponge iron deoxidant, a spongy porous iron grain, sponge iron for the dissolved oxygen in the water filter material (also known as deoxidizer) is made of high quality mineral powder, using the REDOX reaction principle, through out in the form of a filter in addition to the lake for pipe, boiler circulating water dissolved oxygen corrosion after dealing with the water dissolved oxygen content can be up to 0.05 mg/L, the deoxidizer has the backwashing frequency is low, high compressive strength, not pulverization, not knot board, specific surface area. The advantages of high activity, the regeneration effect is good. In after activation treatment of sponge iron deoxidant, a spongy porous iron grain, for the dissolved oxygen in the water and the opportunity of active iron reaction, accelerate the REDOX reaction, and the dissolved oxygen in the water the chemical reaction is as follows: Fe + H2O + 1/2 o2 - Fe2 + + 2 OH - Fe2 + + 2 OH - + 1/2 H2O + 1/4 o2 - Fe (OH) 3 left application: can be used for all kinds of boiler and heat pipe filling water, industrial circulating cooling water, etc. Need to remove dissolved oxygen in water.
【The working principle of sponge iron filter 】 
Room temperature oxygen is a chemical oxygen filter type, is to use the activity of specializing in the production of sponge iron (direct reduced iron) to remove dissolved oxygen in water, sponge iron main component is iron, 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) 2, Fe (OH) 3 is not easy to dissolve in water floc, when with water flow through the rest of the sponge iron particles was stopped, as long as the use of a certain intensity backwashing water can rinse (about 5 minutes). The consumption of sponge iron is very low, according to different water quality and water quantity processing, the general 3-6 months added a can. (after oxygen adding a small amount of iron ions, generally 0.2 0.5 mg/L, for hot water boiler is still in accordance with the provisions of the state of water quality standard, but for the steam boiler or have strict request for feed water of Fe2 + water supply oxygen, can add iron removal equipment, remove the water of Fe2 +, this center equipped with all kinds of ion exchange of iron removal equipment for users to choose.) As water deoxidizer sponge iron is the use of particle size under - 200 mesh Fe3O4 powder bonded together, particle size is about 2-5 mm. Because of its reduction process substitution reaction, form a certain number of gap, the gap and the powder particles bonding, makes the deoxidant high porosity, specific surface
