Yes, but it is complicated. Eh, pH, ORP, microbe population, sulfate, organic carbon and iron are all variables on heavy metal removal. Understand the existing biological and physico-chemical properties of a site-specific conditions before attempting to change them. You will probably have to work within the existing pH range, especially with groundwater. Working with Jan […]
The particle size for Ferox- ZVI is in the table below: The our 5 micron ZVI is analyzed by FSSS uses surface area measurements to determine the average particle size of the sample based on air permeability, material density (7.86 kg/dm3 in the case of iron), and resulting pressure changes in the packed sample container. […]
Of course, ZVI is well known for its ability to degrade cVOCs, but it also has shown good degradation of a variety of COCs, such as TPH, TNT, chloroform, etc. Researchers have shown some of the novel chemistries that ZVI can do. These reactions include the anaerobic reactions with sulfidated-iron and the aerobic reactions with […]
What is the difference between Sodium and Potassium Permanganate? Introduction Permanganate is a powerful oxidant which chemically reduces chlorinated ethene compounds quickly and effectively without forming daughter products such as dichloroethene and vinyl chloride. It can be provided as sodium and potassium salt. Both versions are equally as effective if in the same molar quantities. […]
