Liquid heavy metal scavenger is a highly efficient wastewater treatment chemical that rapidly and strongly chelates with various heavy metal ions—such as chromium, nickel, copper, and zinc—in wastewater under a wide pH range and ambient temperature, forming stable, water-insoluble precipitates. Its key advantages include fast reaction kinetics, high removal efficiency, and the ability to significantly reduce heavy metal concentrations in wastewater to meet discharge standards. Additionally, the sludge generated by this scavenger is minimal in volume and highly stable, facilitating subsequent handling and disposal. Moreover, the liquid heavy metal scavenger is easy to use and highly adaptable, making it suitable for widespread application in wastewater treatment across industries such as electroplating, metallurgy, and chemical manufacturing.
Product Introduction：
Liquid heavy metal scavenger is a chemical reagent specifically developed for treating heavy metal-containing wastewater, also known as a heavy metal precipitant or heavy metal ion chelating agent. It is primarily composed of organic molecules with high affinity for heavy metal ions and can strongly chelate ions such as copper, nickel, lead, zinc, and cadmium, forming insoluble chelated precipitates that effectively remove these metals from the environment. Additionally, it can reduce heavy metal ions to metallic deposits through electrochemical reactions, enabling both capture and recovery of the metals.
Product Advantages：
High adsorption capacity with selectivity: It can efficiently adsorb various heavy metal ions and remains effective even at low concentrations of heavy metals in wastewater.
Wide applicability: It can be used under various environmental conditions and is effective across a broad range of pollutant concentrations. It remains reactive over a pH range of 2 to 14, with optimal performance typically observed under alkaline conditions (pH approximately 8–11).
Prevents re-dissolution of heavy metals: It forms stable complexes with heavy metal ions, effectively inhibiting their re-dissolution and re-release, thereby ensuring long-lasting capture performance.
Multifunctional: It not only removes heavy metal ions but also effectively reduces COD, exhibits strong flocculation performance, and simultaneously minimizes sludge generation.
Good safety profile: When the reagent is slightly overdosed, it co-precipitates with the sludge and does not cause sulfide levels to exceed regulatory limits.
Service Industries：
It is widely used in industries that generate heavy metal-containing wastewater, such as mining, non-ferrous metal smelting, electroplating, petrochemicals, battery manufacturing, textile dyeing, ceramics, plastics, printed circuit board (PCB) production, surface treatment, and electronics. It effectively treats the heavy metal-laden effluents produced during manufacturing processes in these industries, consistently bringing all heavy metal concentrations in the treated wastewater into compliance with national discharge standards.
