Answer 2

Answer:

The sewage processes refers to a method where sewage water is separated from other solid house waste from sewage system. The waste water that remains behind after the treatment process is disinfected with chemicals that kill microbes and toxins.

Effluents, the waste water is released to water bodies within as fresh water because it's not potable. It undergoes primary treatment in the primary settling tank where the solids in the waste stream settle out as sludge and water. Primary treatment removes toxic chemicals from water.

In the secondary treatment, oxygen is added to the waste water to speed up the growth of micro organisms. The microbes consume the wastes and settle to the bottom of the tank. A significant portion of toxic chemicals are removed in the process.

The remaing waste water is disinfected and treated before is released into the receiving water bodies.
