The limitations include the high costs associated with the necessary equipment and technology.

How does neutralization contribute to waste treatment?

Neutralization helps balance the pH of waste, making it less harmful.

What is the purpose of coagulation and flocculation in waste treatment?

Coagulation and flocculation are used to remove suspended particles from the waste.

In what way do oxidation and reduction processes help in environmental safety?

Oxidation and reduction processes break down hazardous substances, such as heavy metals and organic compounds, thereby reducing their toxicity.

What specific pollutants can advanced oxidation processes address effectively?

Advanced oxidation processes can effectively address pollutants that are very difficult to treat or decompose.

What are the key concepts summarized at the end of the video?

The key concepts include neutralization, coagulation and flocculation, oxidation and reduction, and advanced oxidation as methods for safe waste treatment.
