Industrial wastewater and hazardous waste require specialized treatment due to their unique composition and potential environmental impact. Unlike municipal or residential wastewater, which typically contains organic matter and nutrients, industrial wastewater often contains heavy metals, toxic chemicals, and complex organic compounds that can be harmful if not treated properly.

Furthermore, hazardous waste may include substances that are flammable, corrosive, or reactive, necessitating strict regulations and advanced treatment methods to ensure that they are safely processed before being released back into the environment. This specialized treatment often involves processes such as chemical neutralization, advanced filtration, and biological treatment specifically designed to handle the pollutants in these types of wastewater.

On the other hand, municipal and residential wastewater usually undergoes standard treatment processes, while stormwater runoff, although potentially containing pollutants, is typically managed through separate systems designed for that purpose, rather than the specialized facilities required for industrial and hazardous waste.
