Can you explain this answer?

Question

Answer

Understanding Disinfection in Water Treatment
Disinfection is a crucial process in water treatment aimed at eliminating harmful microorganisms. However, certain characteristics are essential for effective disinfection. Among the options provided, option 'C' is incorrect because it suggests that disinfection should render the water toxic for its intended use. Here’s why this is not appropriate:
Key Characteristics of Effective Disinfection

Readily Available and Affordable: Disinfectants should be easily accessible and economical to ensure widespread use.
Simple Application: The methods for applying disinfectants should be straightforward, allowing for consistent and effective use without requiring complex training.
Safeguard Against Re-contamination: Disinfection should ideally include measures to prevent the reintroduction of pathogens post-treatment, ensuring long-term safety.
Toxicity Consideration: While disinfection processes must eliminate pathogens, the end product (water) should not remain toxic. Water must be safe for consumption and other intended uses, such as irrigation or industrial applications.

Conclusion
Disinfection aims to produce safe water, free from harmful microorganisms without compromising its usability. Rendering water toxic contradicts the fundamental purpose of disinfection, which is to protect public health. This highlights that option 'C' is indeed the incorrect statement regarding disinfection practices in water treatment.

Answer

Disinfection should not render the water toxic, objectionable and unpalatable for its intended use.
