Sponge filter (also known as oxygen scavenger) using high-quality ore, the use of oxidation-reduction reaction mechanism, through the way of filtering sediment addition exclusion, on the pipe, corrosion of the boiler is circulating water dissolved oxygen dissolved oxygen content in the treated water can be achieved 0.05 mg / L below the backwash of the oxygen scavenger with low frequency, high compressive strength, no powder, no end plates, large surface area. High activity and good regeneration effect. 

 After treatment, the sponge iron activated oxygen scavenger, was porous sponge iron particles, the dissolved oxygen in water to provide for the active iron and react with the opportunity to accelerate the redox reaction, it dissolved oxygen in water chemistry as follows: Fe + H2O +1 / 2O2 → Fe2 + +2 OH-Fe2 + +2 OH-+1 / 2H2O +1 / 4O2 → Fe (OH) 3 ↓ Applications: can be used for a variety of boilers, heat pipes supply water, industrial cooling need to remove dissolved oxygen, water and other places. 

 Features: 

 1. Room temperature operation, without heating, to overcome the heat, vacuum and heating energy consumption of the shortcomings of oxygen; 

 2. Land, space is small, easy to install, to overcome the heat, the inconvenience of installing high vacuum deaerator; 

 3 is insoluble in water, soft floc, when it accumulated to a certain extent, you can drain through the backwash, the sponge iron capacity to return to the initial oxygen. 

 How it works: sponge iron oxygen scavenger is activated by high activity after the filler is a porous sponge-like iron tablets, to provide dissolved oxygen to react with the active iron conditions, when water containing oxygen through the sponge iron when the oxygen in the water and the occurrence of complete oxidation of iron, thereby eliminating the dissolved oxygen content in water.
