Sample Questions

1. What is the primary purpose of a sedimentation tank in water treatment?

A. Remove dissolved solids
B. Remove suspended particles
C. Add chemicals
D. Increase pressure

Answer: B. Remove suspended particles

Explanation:
A sedimentation tank is used to remove suspended solids from water by allowing them to settle under gravity. As water flows slowly through the tank, heavier particles sink to the bottom, forming sludge that can be removed. This process is an important step before filtration, as it reduces the load on downstream treatment processes. It does not remove dissolved solids, which require chemical or advanced treatment methods. Understanding sedimentation is essential for the FE Environmental exam because it is a fundamental concept in water treatment system design and operation.

2. What is BOD (Biochemical Oxygen Demand)?

A. Oxygen in air
B. Oxygen needed by microorganisms
C. Chemical concentration
D. Water pressure

Answer: B

Explanation:
Biochemical Oxygen Demand (BOD) measures the amount of oxygen required by microorganisms to decompose organic matter in water. High BOD indicates high levels of pollution, as more oxygen is needed for biological activity. This can reduce oxygen available for aquatic life, leading to environmental damage. BOD is a key indicator of water quality and is commonly tested on the FE Environmental exam. Engineers use BOD values to design wastewater treatment systems and assess environmental impact.

---

3. What is the main source of air pollution?

A. Water
B. Combustion processes
C. Soil
D. Plants

Answer: B

Explanation:
Combustion processes, such as burning fossil fuels in vehicles, power plants, and industries, are the primary source of air pollution. These processes release pollutants like carbon monoxide, nitrogen oxides, and particulate matter into the atmosphere. Understanding pollution sources is essential for designing control strategies and improving air quality. The FE Environmental exam often includes questions about pollution sources and their environmental impact.

---

4. What is pH a measure of?

A. Temperature
B. Acidity or alkalinity
C. Pressure
D. Flow rate

Answer: B

Explanation:
pH measures the acidity or alkalinity of a solution on a scale from 0 to 14. A pH of 7 is neutral, values below 7 are acidic, and values above 7 are basic. pH is important in water treatment, as it affects chemical reactions and biological processes. Maintaining proper pH levels is essential for safe drinking water and effective wastewater treatment. The FE Environmental exam frequently tests pH concepts because they are fundamental to environmental engineering.
