2 / 10

Where does the feed water enter in a single-pass reverse osmosis plant?

C) At the pre-treatment unit

B) Directly into the membrane module

A) Into the permeate line

D) Into the product tank

3 / 10

What is the function of the concentrate (brine) outlet in a reverse osmosis plant?

C) To recycle water back to the feed

D) To cool down the water

B) To discharge concentrated salts and impurities not passing through the membrane

A) To remove filtered water

4 / 10

What is the primary function of the product tank in a single-pass reverse osmosis system?

C) To mix feed water and permeate

B) To store purified water for distribution

A) To hold pre-treated water

D) To increase water pressure

5 / 10

Which parameter is commonly monitored to ensure proper operation of the high-pressure pump?

B) pH level

C) Pressure gauge readings

D) Temperature changes

A) Water color

6 / 10

What is the role of the high-pressure pump in a single-pass reverse osmosis system?

C) To decrease the water temperature

D) To mix permeate and concentrate streams

B) To increase water pressure, allowing it to pass through the membrane

A) To add minerals to the water

7 / 10

In which direction does the feed water flow in relation to the semi-permeable membrane?

D) Opposite to the high-pressure pump

B) Across the membrane surface in a cross-flow manner

A) Perpendicular to the membrane

C) Directly through the permeate line

8 / 10

What is the purpose of the permeate line in a single-pass reverse osmosis plant?

C) To recirculate water back to the membrane

A) To carry pre-filtered water

B) To transport purified water to the product tank

D) To mix with brine

9 / 10

Why is a pre-treatment unit used in a single-pass reverse osmosis system?

C) To filter and condition feed water, preventing fouling of the membrane

D) To reduce the feed water flow

A) To heat the water

B) To add salt to the feed water

10 / 10

Where is the semi-permeable membrane positioned in a single-pass reverse osmosis plant?

D) In the brine discharge line

A) After the pre-treatment unit and high-pressure pump

C) Before the high-pressure pump

B) At the beginning of the system
