What is one way that industrial effluents are typically treated before release into the environment?

Industrial effluent refers to the wastewater, liquids, or gases produced as a byproduct of industrial processes. Industrial effluents often contain a wide range of pollutants, including heavy metals, acids, and other toxic materials, which can be treated through various methods such as the oxidation process. Oxidation occurs in two ways chemical and biological process.

Chemical oxidation: This process involves adding chemicals, such as hydrogen peroxide or ozone, to the wastewater to oxidize and destroy pollutants.

Biological oxidation: This process uses microorganisms, such as bacteria, to break down the pollutants in the wastewater through a process called biodegradation.
