Can the iron powder reduction process still be used?
Thread Content
The iron powder reduction process is an obsolete method in production processes, but can it still be used for wastewater treatment?
The dissolution rate of iron powder is unstable; it is not as effective for coagulation and sedimentation as the use of iron salts, whose amount can be adjusted as needed. Therefore, iron salts offer more stable reduction, making color removal or heavy metal removal pointless in this context. However, when dealing with *** types, such as electroplating anti-staining salts, iron powder must be used to reduce them to aniline in order to carry out biochemical reactions. Therefore, iron powder reduction is used in processes where reduction is necessary.
