FAQs on Disinfection with Chlorine Video Lecture - Environmental Engineering - Civil Engineering (CE)

1. What is disinfection with chlorine in civil engineering?
Ans. Disinfection with chlorine in civil engineering is a process used to kill or inactivate harmful microorganisms in water or wastewater. Chlorine is added to the water to eliminate bacteria, viruses, and other pathogens, making it safe for drinking or other uses.
2. How does disinfection with chlorine work in civil engineering?
Ans. Chlorine disinfection works by oxidizing the cell walls and enzymes of microorganisms, disrupting their metabolic processes and leading to their destruction. This process effectively kills harmful bacteria and viruses, ensuring the safety of the water supply.
3. What are the advantages of using chlorine for disinfection in civil engineering?
Ans. Chlorine disinfection offers several advantages in civil engineering. Firstly, it is a widely available and cost-effective method for treating large volumes of water. Secondly, it has a long-lasting residual effect, providing ongoing protection against microbial contamination. Lastly, it is relatively easy to monitor and control the chlorine dosage to ensure effective disinfection.
4. Are there any drawbacks or limitations to using chlorine for disinfection in civil engineering?
Ans. While chlorine disinfection is widely used and effective, it does have some drawbacks. One limitation is that chlorine can react with certain organic compounds present in water, forming disinfection byproducts (DBPs) that may pose health risks. Additionally, chlorine can have a strong odor and taste, which may be undesirable for some consumers. Proper monitoring and control of chlorine levels are essential to mitigate these issues.
5. Are there alternative disinfection methods to chlorine in civil engineering?
Ans. Yes, there are alternative disinfection methods to chlorine in civil engineering. Some commonly used alternatives include ultraviolet (UV) disinfection, ozone disinfection, and chloramine disinfection. These methods offer their own advantages and limitations, and the choice of disinfection method depends on factors such as water quality, treatment goals, and regulatory requirements.
