Answer:
Reverse osmosis
Explanation:
In order to purify the water which has been contaminated with salt and microorganisms, reverse osmosis will be the best way. In reverse osmosis a pressure is applied on the salt side of the impure water using a pump. Doing this prompts the pure water to leave the salt side so pure water moves another side of the semi permeable membrane. The semi permeable also filters the microorganisms. Hence, pure water can be obtained easily from this impure sample. The RO at our houses use this process to purify water.
