The answer is Bacterial pollution will be reduced the most.

Explanation:

Sewage is the waste water from the house hold after being used for different purposes. Mostly sewage water contains the waste from Toilets, Kitchen and laundry. Raw sewage waste contains a lot of harmful bacteria such as E-coli and its contamination can cause many diseases like hepatitis A, Diarrhea, Salmonella etc. When this sewage is dumped directly to the water bodies it pollutes the environment and cause health issues to the organisms living there.

Waste water treatment plants remove the harmful chemicals and bacteria from sewage and make it safe for the environment. Few methods used to kill bacteria from sewage waste are chlorination, Ozonation, Filtration, and UV radiations.
