What is commonly used to disinfect water storage tanks?

Hypochlorite, particularly in the form of sodium hypochlorite, is widely used for disinfecting water storage tanks due to its efficacy in killing a broad spectrum of pathogens, including bacteria, viruses, and protozoa. This compound is effective in maintaining the quality of water by preventing microbial growth, ensuring that the water remains safe for consumption.

Hypochlorite can be easily dosed into water systems, allowing for precise control over concentration levels to achieve effective disinfection. It also has the advantage of being relatively stable compared to other disinfectants and can be used in both liquid and solid (tablet) forms. Additionally, its effectiveness at a variety of pH levels makes it a preferred choice for treating water in diverse conditions.

Other options, while they have their own uses in water treatment, are not as commonly employed for disinfecting storage tanks. Hydrochloric acid is typically used for adjusting pH levels or cleaning equipment rather than direct disinfection. Chlorine tablets, while effective, are often a form of hypochlorite, and the direct use of hypochlorite is more versatile and commonly accepted. Ozone, while an effective disinfectant, requires more complex equipment for generation and application, which may not be as
