Shenyang sponge iron prices, sponge iron boiler oxygen product

Sponge iron due to a large surface area, surface area can be high, there is a strong electrochemical enrichment strong reduction, physical adsorption and flocculation and other superior physical and chemical properties, so the boiler water oxygen, phosphorus wastewater, organic wastewater, wastewater treatment of electroplating wastewater and nitrates in certain applications and research. But all reports, the sponge material for water treatment, mostly for industrial use sponge iron, due to the different production purposes, mainly to consider raising industrial sponge sponge iron metallization ratio, lower impurity content and other aspects of sponge iron, while the the degree of crystallization associated with the treatment of the reduced iron grains have sufficient surface area and strength, etc. are not considered. Therefore, the sponge iron industry in general is not very high surface energy, and easy chalking, low contaminant removal efficiency. Sponge iron filter (also called oxygen scavenger) using sponge iron upon activation, the use of oxidation-reduction reaction principle, through the filter precipitate way except to exclude oxygen circulating water used in pipes, boilers and circulating water when , the dissolved oxygen content of the treated water can be reduced to 0.05mg / L or less, and the oxygen scavenger having backwash frequency is low, high compressive strength, not powder, not compacted, large surface area. High activity, regeneration and good, full compliance with state water quality standards for boilers. Sponge iron Main technical characteristics: 1, room temperature operation, without heating, to overcome the heat, vacuum oxygen and weaknesses of heating energy; 2, an area accounting for a small space, easy to install, to overcome the heat, high-mounted vacuum oxygen inconvenience; 3, the dissolved oxygen after treatment is not dissolved in water soft floc, when it accumulated to a certain extent, they can drain through the backwash, make sponge iron recovery to the initial oxygen capacity.

Sponge packaging and storage: 25kg / bag (woven bag lined with polyethylene plastic film). Note that during storage, moisture, sun, water, try to avoid packaging damaged, so as not to affect the oxygen effect. With the continuous progress of science and technology, people development and utilization of mineral containing cadmium increasingly widespread, a large number of waste containing cadmium in the form of waste discharged into the environment, causing serious environmental pollution, to the ecological environment and human health caused serious threats.
