Waste Water Treatment

What is the primary treatment process in waste water treatment?

• Physical processes

• Emotional processes

• Chemical processes

• Biological processes

Explain the secondary treatment process in waste water treatment.

What is the purpose of tertiary treatment process in waste water treatment?

• To speed up the decomposition of the wastewater

• To reduce the quality of the wastewater

• To further purify the wastewater by removing remaining contaminants

• To add more contaminants to the wastewater

Describe the biological treatment methods used in waste water treatment.

• use of chemical agents to remove impurities from the water

• use of physical filtration to separate solids from the water

• heat evaporates water and leave behind impurities

• microorganisms break down organic matter in the water.

How are chemical treatment methods used in waste water treatment?

• To make the water more polluted

• To remove contaminants and pollutants from the water.

• To add more contaminants to the water

• To increase the level of toxins in the water

Explain the concept of grey water and its significance in waste water treatment.

• Grey water is water that is naturally grey in color and cannot be treated for reuse

• Grey water is water that comes from toilets and is not suitable for reuse

• Grey water is water that is only used for industrial purposes and cannot be treated

• Grey water is wastewater from non-toilet plumbing fixtures and has the potential to be reused for other purposes.

What are the key components of the primary treatment process?

• Physical separation of solid waste

• Emulsification of hazardous waste

• Biological treatment of gaseous waste

• Chemical treatment of liquid waste

Discuss the role of microorganisms in secondary treatment process.

• Microorganisms break down organic matter and reduce pollutants in the wastewater.

• Microorganisms only break down inorganic matter in the wastewater.

• Microorganisms have no role in the secondary treatment process.

• Microorganisms increase the level of pollutants in the wastewater.

How does the use of coagulants and flocculants contribute to chemical treatment methods in waste water treatment?

• They contribute to the growth of bacteria in the wastewater

• They have no impact on the treatment of wastewater

• They help to increase the acidity of the wastewater

• They help to clump together particles in the wastewater, making it easier to remove them through filtration or sedimentation.
