Water purification materials plant in Gongyi City Hanbang production of sponge iron filter (oxygen scavenger) at room temperature is massive, is an environmentally friendly water treatment media. High activity obtained by activation treatment, large surface area of ??sponge iron filter type oxygen scavenger. The effect of treatment of industrial water at room temperature (or soft) have achieved under ideal (residual oxygen content: 0.03-0.05mg / L), the product facilities with less investment, easy maintenance, low transportation costs, and good effect of oxygen, can preservative widely used in boilers and water recycling equipment, which is a highly cost-effective energy-saving products. Oxygen Principle: the specific surface area has enormous sponge to filter, when water containing dissolved oxygen by sponge iron, oxygen in the water and sponge iron oxidation occurs completely raw. The chemical reaction is as follows: 2Fe + 2H2O + O2 --- 2Fe (OH) 2 2Fe (OH) 2 + H2O + 2O2 --- 2Fe (OH) 3 the reaction product of Fe (OH) 3 is insoluble in water, soft fluff which, when it accumulated to a certain extent, you can through the backwash drain, return to the initial oxygen scavenging capacity. Applications: http://www.zzshb.com/ sponge iron filter (oxygen scavenger) applies to all kinds of boilers, heat exchangers, heat pipes water, industrial cooling water and oil field water. Features: 1, long life, non-toxic, do not pollute the environment, water oxygen content stabilize at 0.05mg / L or less, and in full compliance with national low-pressure boiler water quality standards (GB1576-2001) requirements. 2, room temperature operation, no heating, low running costs, overcome the shortcomings of thermal oxygen, vacuum oxygen required heating energy consumption. 3, with less oxygen scavenger consumption generally 1 ton of water 25g. 4, backwashing low frequency, good regeneration.
