heavy metal removal

Heavy metal removal is the process of eliminating toxic metals like lead, mercury, and cadmium from water, soil, or air to make the environment safer. Techniques include filtration with specialized filters, chemical treatments that cause metals to settle out or change into harmless forms, and biological methods using plants or microbes to absorb metals. Effective removal reduces health risks and protects ecosystems. The choice of method depends on the type and concentration of metals, as well as the specific context of contamination.
