Which oxidizing agent is used to treat industrial wastewater?

Hydrogen peroxide is an effective oxidizing agent used in industrial wastewater treatment primarily due to its ability to break down organic contaminants and reduce chemical oxygen demand (COD). As an oxidizer, it facilitates various chemical reactions that help convert harmful substances into less toxic or harmless compounds.

Additionally, hydrogen peroxide has the advantage of decomposing into water and oxygen, making it environmentally friendly. This process is particularly useful in situations where the formation of harmful byproducts must be minimized, such as in the treatment of specific industrial wastes.

While sodium hypochlorite, chlorine gas, and ozone are also recognized as oxidizing agents in wastewater treatment, they each have limitations or specific contexts in which they are more suitable. For example, sodium hypochlorite and chlorine gas can contribute to the formation of harmful chlorinated byproducts, and ozone, while very effective, is often more costly and requires specific handling protocols. Therefore, hydrogen peroxide stands out as a viable option for efficient and environmentally conscious treatment of industrial wastewater.
