High quality sponge iron filter for water treatment with sponge iron



Sponge iron can be widely used in the corrosion of boiler and circulating water equipment, it is a kind of cost-effective energy-saving product.
Using a sponge iron with a large surface area as the filter material, the oxygen and sponge iron in the water will have a complete oxidation reaction when the water containing dissolved oxygen is passed through the sponge iron.
The chemical reaction is as follows: Fe 2 + 2 H2O + O2-2 Fe (OH) 2, 2 Fe (OH) 2 + 2 H2O + O2-2 Fe (OH) 3, the reaction product Fe (OH) 3 soft floc is insoluble in water, when it is accumulated to a certain extent, can through the backwash drainage, restore to the original deoxidization ability.
 
Specific application of the following aspects:
1. Water supply for hot water boiler;
2. Suitable for water supply of low-pressure steam boiler;
3. Suitable for water supply of industrial circulating cooling water;
4. Apply to oilfield waterflooding


precautions for sponge iron use
 
After oxygen increased a small amount of iron ions in water, 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 iron ions in the water.
Note: the technical features of sponge iron deaerator are adopted:
1. The normal temperature operation realizes the removal of oxygen and water without heating, which can overcome the shortcomings of heat energy, vacuum deaerating and heating energy dissipation.
2. The water supply can be supplied at any time, without the need for oxygen tank, the preparation time is not required, and the work efficiency is improved.
3. Small space, easy installation, low installation of equipment, simple process, high requirement of high level, eliminate the inconvenience of high installation.
4. In addition to the stable and reliable effect of oxygen, the dissolved oxygen content in the water is stable and is not equal to 0.05 mg/L, which meets the water quality standard of the low pressure boiler.
