Final answer:
Regulated Metal Deposition (RMD®) is a treatment technique used to regulate the concentration of metals in water sources to prevent contamination. It is used in industries such as mining, metallurgy, solid waste disposal, and battery manufacturing.
Step-by-step explanation:
Regulated Metal Deposition (RMD®) is a treatment technique used in certain industries to reduce the level of contaminants, specifically metals, in water sources. It is typically used to regulate the concentration of dissolved iron and molybdenum relative to dissolved carbon. This technique is important in preventing the potential contamination of groundwater due to industrial activities like mining, metallurgy, solid waste disposal, and battery manufacturing.
