Metal chelating agents
CMA products are high-molecular-weight, water-soluble heavy metal chelating agents. They are used to treat general wastewater containing heavy metals. It utilizes the chelated sulfide groups within the structural molecules to form stable colloidal plumes with heavy metals. Then, coagulants and polymers are used to bridge the mixture, forming stable and large flocs, thereby achieving rapid coagulation and sedimentation.
The CMA-3000 and CMA-5000 series products are compound formulations primarily composed of thiocarbamates. These series products, mainly sodium thiocarbamate salts, exhibit excellent chelation and removal effects for low concentrations of heavy metals and have extremely low heavy metal re-dissolution rates.
The CMA-700 series products are compound formulations of inorganic sulfide salts. They have extremely high capture and removal efficiency for metal ions such as copper, nickel, zinc, and lead.
