Identify the incorrect statement regarding aeration process.a)It remov...
Incorrect Statement: It increases the carbon dioxide content of water
Explanation:
Aeration is a process used to increase the dissolved oxygen content in water by introducing air or oxygen into it. It is commonly used in water treatment processes to remove taste, odor, and certain gases such as carbon dioxide. However, the given statement is incorrect as aeration does not increase the carbon dioxide content of water. Instead, it helps in removing carbon dioxide from water.
Importance of Aeration:
Aeration is an important process in various industries and water treatment plants. It serves several purposes, including:
1. Removal of Taste and Odor: Aeration helps in removing unpleasant tastes and odors from water, which may be caused by dissolved gases such as hydrogen sulfide or volatile organic compounds.
2. Increased Dissolved Oxygen: Aeration is primarily used to increase the dissolved oxygen content in water. This is crucial for the survival of aquatic organisms and for maintaining the overall health of water bodies. Aeration enhances the exchange of gases between water and the atmosphere, allowing oxygen to dissolve into the water.
3. Removal of Volatile Gases: Aeration also aids in the removal of volatile gases such as carbon dioxide, methane, and hydrogen sulfide. These gases can contribute to acidity, alkalinity, and corrosion issues in water.
4. Oxidation of Iron and Manganese: Aeration promotes the oxidation of dissolved iron and manganese, converting them into insoluble forms that can be easily removed through filtration or sedimentation.
5. Chemical Mixing and Reactions: Aeration can be used to mix chemicals with water, promoting chemical reactions or facilitating the dissolution of certain substances.
In conclusion, the incorrect statement in the given options is option C, which suggests that aeration increases the carbon dioxide content of water. Aeration actually aids in removing carbon dioxide and other volatile gases, while increasing the dissolved oxygen content and improving the overall quality of water.
