Question

discuss the methods involved and the mode of action in wastewater treatment plant​

Answer 1

Answer:

Wastewater treatment plants (WWTP) use a combination of physical, chemical, and biological processes to treat and remove pollutants from wastewater before it is released into the environment.

Explanation:

The treatment process typically involves four stages: primary treatment, secondary treatment, tertiary treatment, and disinfection. The primary treatment process involves the removal of large solid materials and grit through physical processes such as screening and sedimentation. In secondary treatment, biological processes such as activated sludge and trickling filters are used to remove organic matter, suspended solids, and dissolved nutrients.

Tertiary treatment involves further removal of contaminants using processes such as sand filtration, membrane filtration, and chemical coagulation. Finally, disinfection is used to kill any remaining pathogens before the treated wastewater is discharged into the environment.

The mode of action in the treatment process involves the removal of contaminants through various physical, chemical, and biological processes. Physical processes such as screening, sedimentation, and filtration remove solid materials, while chemical processes such as coagulation and flocculation remove dissolved contaminants. Biological processes such as activated sludge and trickling filters use microorganisms to break down organic matter and convert it into harmless byproducts.

Overall, wastewater treatment plants play a critical role in protecting public health and the environment by removing pollutants and contaminants from wastewater before it is discharged into the environment. The treatment process involves a combination of physical, chemical, and biological processes, each with its own unique mode of action.
