1 / 10

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

B) At the beginning of the system

D) In the brine discharge line

C) Before the high-pressure pump

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

2 / 10

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

A) To remove filtered water

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

C) To recycle water back to the feed

D) To cool down the water

3 / 10

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

C) At the pre-treatment unit

A) Into the permeate line

B) Directly into the membrane module

D) Into the product tank

4 / 10

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

A) To hold pre-treated water

B) To store purified water for distribution

C) To mix feed water and permeate

D) To increase water pressure

5 / 10

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

A) Perpendicular to the membrane

D) Opposite to the high-pressure pump

C) Directly through the permeate line

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

6 / 10

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

B) To add salt to the feed water

D) To reduce the feed water flow

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

A) To heat the water

7 / 10

Where would you place a TDS (Total Dissolved Solids) meter in a reverse osmosis plant?

A) In the feedwater inlet only

C) In the permeate line to measure water purity

D) After the pre-treatment unit only

B) In the concentrate line

8 / 10

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

C) Pressure gauge readings

D) Temperature changes

A) Water color

B) pH level

9 / 10

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

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

D) To mix permeate and concentrate streams

A) To add minerals to the water

C) To decrease the water temperature

10 / 10

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

A) To carry pre-filtered water

B) To transport purified water to the product tank

D) To mix with brine

C) To recirculate water back to the membrane
