Wastewater treatment agent

Wastewater treatment agents refer to chemicals used to treat harmful substances in wastewater, in order to achieve purification and discharge requirements. Common wastewater treatment agents include the following categories:

Oxidants: Oxidants can be used to decompose organic substances in organic wastewater, such as hydrogen peroxide (H2O2), potassium permanganate (KMnO4), etc. They can oxidize organic matter and convert it into harmless substances such as carbon dioxide, water, and inorganic salts.

Reductant: Reductant can be used to reduce heavy metal ions in wastewater, converting them into insoluble precipitates and precipitating them, such as sodium sulfite (Na2SO3), sodium thiosulfate (Na2S2O3), etc.

Flocculant: Flocculant is used to aggregate small suspended particles in wastewater, forming larger flocs for easy sedimentation or filtration, such as polyaluminum chloride (PAC), polyacrylamide (PAM), etc.

Chelating agent: Chelating agent can form stable complexes with metal ions in wastewater, reducing the activity and harmfulness of metal ions, such as EDTA (ethylene diamine tetraacetic acid).

PH regulator: In the process of wastewater treatment, by adjusting the pH value of the wastewater, the solubility, ionization degree, and activity of substances can be changed, such as limestone (CaCO3), sulfuric acid (H2SO4), etc.

Biological treatment agents: Biological treatment agents are mainly used for the biodegradation of organic substances in wastewater, which are decomposed and converted into harmless substances through the action of microorganisms, such as activated sludge, bacterial culture agents, etc.

The above only lists some common types of wastewater treatment agents and representative chemicals. In practical applications, it is necessary to select appropriate reagents based on factors such as the characteristics, treatment requirements, and process flow of wastewater, and follow relevant environmental regulations and standards for wastewater treatment. It is recommended to follow the instructions and consult professional advice when using wastewater treatment agents.
