摘要：

This disclosure provides methods and compositions for removing COD-causing contaminants from water, such as cosmetic product production wastewater and personal care product production wastewater. The methods involve controlling system parameters in order to hold iron as an iron(II) species. Iron(II) has increased solubility and therefore is more active against the specific contaminants present in the wastewater.
