What is used to remove algae and slime from the inside of a water main?

• A. Polymer
• B. Carbon
• C. Sodium thiosulfate
• D. Chlorine

Answer: (D)

Chlorine is widely recognized for its effectiveness in water treatment, particularly for disinfection purposes. When it comes to removing algae and slime from the inside of a water main, chlorine serves as a powerful biocide that targets and eliminates microorganisms, including algae. Its oxidizing properties disrupt the cellular structure of algae and other organic materials, leading to their subsequent breakdown and removal. Using chlorine in water mains not only reduces the presence of slime and algae but also helps maintain water quality by inhibiting future growth. This is critical in systems where stagnant water or low-flow conditions might encourage biofilm formation. Chlorination is a standard practice in many water distribution systems, ensuring both safety and quality of drinking water over time. In contrast, options like polymer and carbon are not specifically designed for the removal of algae or slime in water mains. Polymers can be utilized in flocculation processes or as coagulants in water treatment, while carbon is typically reserved for adsorption of organic compounds and taste and odor control rather than biological growth removal. Sodium thiosulfate, primarily known for its dechlorination properties, does not have the same efficacy as chlorine in addressing algal growth or slime removal, making it unsuitable for this specific application. Therefore, chlorine's
