Humber/Ontario Real Estate Course 2 Exam Practice

Owner Jones is discussing equipment used in his cottage to remove solids and minerals from well water. If the system includes a semi-permeable membrane and a storage tank, what is the process?

1. Carbon filtration.

2. Reverse osmosis.

3. Aquifer cleansing.

4. Chlorination injection.

The correct answer is: Reverse osmosis.

The correct answer is B: Reverse osmosis. Reverse osmosis is a water purification process that uses a semi-permeable membrane to remove ions, molecules, and larger particles from drinking water. In the context of the question, the equipment described, including a semi-permeable membrane and a storage tank, are characteristic of a reverse osmosis system used for purifying well water by removing solids and minerals. Option A, carbon filtration, involves the use of activated carbon to remove impurities and contaminants from water by adsorption. This method is different from the process described in the question involving a semi-permeable membrane and storage tank. Option C, aquifer cleansing, refers to the process of cleaning or restoring an aquifer, which is a permeable underground layer of rock or sediment that holds water. This process is not relevant to the equipment described in the question related to well water purification. Option D, chlorination injection, involves adding chlorine to water to disinfect it and kill bacteria and other harmful microorganisms. While chlorination is a common water treatment method, it is not the same as the process of using a semi-permeable membrane in reverse osmosis for purifying well water.
