Question

what are the different types of sewage water treatment​

Answer 1

Answer:

Wastewater can be treated to three standards:

1. Primary - minimal treatment involving flotation and settlement to separate solids and liquids, and disposal of the clarified but still contaminated effluent (such as septic tanks and composting toilets).
2. Secondary - more advanced treatment using air and biological processes to decompose the solids and chlorine to disinfect the liquid to a standard safe for irrigation (such as aerated wastewater treatment systems).
3. Tertiary - highly advanced systems that use air and biological processes as well as membranes and UV disinfection to treat wastewater to a very high standard (such as membrane filtration and advanced aerated wastewater treatment systems).
