ZA-TECH_Capture and immobilize heavy metals


Heavy metals, e.g., Ag, As, Ba, Cd, Cr, Cu, Hg, Ni, Pb, Sb, Se, Tl, and Zn, are metals and metalloids that pose a threat to humans and the environment. They exist in almost all solid wastes and wastewater and are the main concern for waste disposal and reuse. If handled improperly, heavy metals will leach out from waste, migrate via soil, water, and air, and enter the human body through the food chain, leading to detrimental impacts on human health and the ecosystem.

​ZA-TECH™ reagents effectively capture and immobilize heavy metals and metalloids in wastes and wastewater, allowing the treated wastes and wastewater to meet any environmental regulation.


The ZA-TECH™ series reagents also tackle other pollutants in waste and wastewater, including oil and grease, COD, ammonia-N, fluoride, and some POPs.
