Product Description
Heavy Metal Chelating Agent is a specialized water treatment chemical designed for the removal of heavy metal ions from industrial wastewater.
It can react with heavy metal ions to form stable, low-solubility compounds that can subsequently be separated from water through precipitation, flocculation and solid-liquid separation.
The product can be used for wastewater containing heavy metals such as copper (Cu), nickel (Ni), zinc (Zn), lead (Pb), cadmium (Cd), mercury (Hg) and other metal ions, subject to the actual wastewater composition and treatment conditions.
It is suitable for applications including electroplating, mining and metallurgy, electronics, metal processing and chemical industrial wastewater treatment.
Hanhai Chemical supplies different Heavy Metal Chelating Agent grades according to the type of heavy metal, concentration, wastewater chemistry and treatment target.

Applications
Electroplating Wastewater
Electroplating wastewater may contain copper, nickel, zinc, chromium and other metal contaminants, depending on the plating process.
Heavy Metal Chelating Agent can be incorporated into an appropriate treatment process to promote the removal of selected dissolved heavy metal ions.
The product type and dosage should be selected according to wastewater composition and the target metal.
Mining & Metallurgical Wastewater
Mining, mineral processing and metallurgical operations can generate wastewater containing various dissolved metals.
Heavy Metal Chelating Agent can be evaluated as part of a treatment program for mine water, mineral processing wastewater and metallurgical wastewater where heavy metal removal is required.
This application is particularly relevant when conventional precipitation alone does not provide the required treatment performance.
Electronics Wastewater
Wastewater generated by electronics and related manufacturing processes may contain copper, nickel and other metal ions.
A suitable chelating agent can help convert selected dissolved metals into forms that are easier to remove through subsequent separation processes.
Metal Processing Wastewater
Surface treatment, metal finishing and related industrial processes may generate wastewater containing different heavy metal ions.
The treatment program should be selected according to the metal species, concentration and existing wastewater treatment process.
Chemical Industrial Wastewater
Heavy Metal Chelating Agent can also be evaluated for selected chemical industrial wastewater where residual heavy metals require further removal.
Laboratory testing is recommended before determining the final chemical dosage and treatment conditions.
How Heavy Metal Chelating Agent Works
Heavy metal ions dissolved in wastewater can be difficult to remove completely through simple physical separation.
A Heavy Metal Chelating Agent reacts with selected metal ions and promotes the formation of low-solubility metal-containing compounds.
These compounds can then be aggregated and separated from the treated water.
A typical process may be:
Heavy Metal Wastewater → pH Adjustment → Heavy Metal Chelating Agent → Flocculation → Sedimentation / Filtration → Treated Water
Depending on the wastewater, the treatment system may also use:
- PAC (Polyaluminium Chloride)
- PAM (Polyacrylamide)
- PFS (Polyferric Sulfate)
- pH adjustment chemicals
- Other coagulants and flocculants
The optimum treatment process should be determined according to the actual wastewater.

FAQ
What is a Heavy Metal Chelating Agent?
A Heavy Metal Chelating Agent is a water treatment chemical used to react with selected heavy metal ions in wastewater and facilitate their subsequent removal through precipitation and solid-liquid separation.
Which heavy metals can it remove?
Depending on the selected product and wastewater conditions, it can be used for treatment involving metals such as copper, nickel, zinc, lead, cadmium and mercury.
Actual removal performance should be confirmed through wastewater testing.
Can it be used for electroplating wastewater?
Yes. Electroplating wastewater is one of the important application areas for heavy metal removal chemicals.
The product should be selected according to the plating process and metal composition of the wastewater.
Can it be used for mining wastewater?
It can be evaluated for mine water, mineral processing wastewater and metallurgical wastewater containing suitable heavy metal contaminants.
Can it be used together with PAM?
Yes. In an appropriate treatment process, PAM can be used to support floc formation and solid-liquid separation after the heavy metal treatment stage.
Can it be used together with PAC or PFS?
Depending on the wastewater, PAC or PFS may be incorporated into the coagulation and flocculation process.
The optimum combination should be confirmed by testing.
What dosage should I use?
There is no universal dosage.
Dosage depends on the heavy metal species, metal concentration, pH, competing substances and required treatment level.
Jar testing or laboratory testing is recommended before determining the final dosage.
Can you guarantee the final heavy metal concentration?
Treatment performance depends on wastewater composition, operating conditions, dosage and the overall treatment process.
For a specific discharge target, wastewater testing should be performed before determining the treatment program.
