Question

Answer

Cleaning of water is the process of removing pollutants from it, making it safe for consumption or other intended uses.
Explanation: When we say 'cleaning water,' we are essentially referring to the process of eliminating contaminants like bacteria, chemicals, sediment, and other impurities that might be present in the water source.
Key points about water cleaning:
Purpose:
To ensure water quality is suitable for drinking, industrial use, irrigation, or returning to the environment.
Process stages:
Depending on the water source and desired quality, cleaning can involve filtration, sedimentation, disinfection, and other methods.
Wastewater treatment:
Cleaning wastewater (sewage) is a specific type of water cleaning process that focuses on removing pollutants from used water before it is released back into the environment.

Answer

Contaminants

Answer

Yes, cleaning of water is a process of removing contaminants. as that water consists of all dust chemicals etc. so for removing contaminants we purify the water to remove contaminants.

Answer

The correct answer is option B) Contaminants because the cleaning of water refers to the process of removing unwanted substances, which are broadly called contaminants. These contaminants can include:

Sediments (like sand, silt, and dirt)
Microorganisms (like bacteria, viruses, and protozoa)
Chemicals and pollutants (like heavy metals, pesticides, and industrial waste)

While sediments (option A), microorganisms (option C), and bacteria (option D) are all types of contaminants, the term 'contaminants' is the most general and includes all these harmful substances. That is why option B is the best answer.

Answer

Understanding Water Cleaning
Cleaning of water is essential for ensuring its safety and suitability for consumption and other uses. The process involves removing various unwanted substances that may compromise water quality.

What Are Contaminants?
- **Contaminants** refer to any physical, chemical, or biological substances that can degrade water quality.
- They can include a wide range of harmful pollutants such as heavy metals, pesticides, industrial chemicals, and organic matter.

Importance of Removing Contaminants
- Removing contaminants is crucial for:
- **Protecting Health**: Contaminated water can lead to diseases and health issues.
- **Environmental Safety**: Pollutants can harm aquatic ecosystems and biodiversity.
- **Ensuring Potability**: Safe drinking water must be free from harmful substances.

Other Substances in Water Cleaning
While sediments, microorganisms, and bacteria are also removed during water cleaning, the term 'contaminants' encompasses a broader category, making it the most appropriate answer.
- **Sediments**: These are solid particles that settle at the bottom but do not necessarily pose a health risk.
- **Microorganisms**: While they can be harmful, they are often a subset of contaminants.
- **Bacteria**: Like microorganisms, bacteria are a specific group that can be harmful but are included within the broader category of contaminants.

Conclusion
In summary, while sediments, microorganisms, and bacteria are important, the term 'contaminants' effectively captures the wide range of harmful substances removed during the water cleaning process. This is why option 'B' is the correct answer.
