What are common methods of algae control in lakes and reservoirs?

• A. Mechanical harvesting and filtration
• B. Bio-remediation and chemical treatments
• C. Copper sulfate and potassium permanganate
• D. Ultraviolet light treatment and aeration

Answer: (C)

Copper sulfate and potassium permanganate are common chemicals used for algae control in lakes and reservoirs. Copper sulfate is known for its ability to inhibit algal growth by disrupting photosynthesis in certain types of algae, making it a widely utilized algaecide. Potassium permanganate, on the other hand, acts as an oxidizing agent and can help manage organic substances in water while also controlling algae populations. These chemical treatments are often used in combination with other methods for more effective management of algae blooms, particularly in larger water bodies where algal overgrowth can lead to significant ecological and aesthetic issues. Other methods, such as mechanical harvesting, bio-remediation, or treatments using ultraviolet light or aeration, have their own applications but may not be as directly recognized as conventional chemical treatments specifically targeting algae.
