Description
Heavy Metal Precipitator
Product Description
It is a high-performance, eco-friendly, and non-toxic chemical designed to effectively remove heavy metals from industrial wastewater. It reacts with a wide range of monovalent and divalent heavy metal ions—such as Fe²⁺, Ni²⁺, Pb²⁺, Cu²⁺, Ag⁺, Zn²⁺, Cd²⁺, Hg²⁺, Ti⁺, and Cr³⁺—to form stable, insoluble compounds that settle out of solution. These precipitates are highly stable and will not redissolve, eliminating the risk of secondary pollution.
Applications
It is suitable for a wide range of industries, including:
-
Coal-fired power plants – Removal of heavy metals from desulfurization wastewater (wet FGD systems)
-
Waste incineration plants – Flue gas treatment for heavy metal removal
-
Industrial wastewater treatment in:
-
Metallurgy
-
Electroplating
-
Electronics
-
Chemical manufacturing
-
Printing
-
Circuit board production
-
Mining
-
Other chemical processing industries

Usage Instructions
-
Analyze the concentration of heavy metal ions in the wastewater. Perform lab-scale dosing tests to determine the optimal dosage. (Recommended dosage: 20–300 ppm)
-
Adjust pH of the wastewater to 7–10 using NaOH before adding it for best performance.
-
Dilute It with water in a dedicated dosing system. Combine with coagulants and flocculants for enhanced treatment.
-
Stirring time: About 30 minutes to ensure full reaction and precipitation.
