Calcium hypochlorite is an effective disinfectant used to treat drinking water in military operations because it releases chlorine, which is a powerful agent for killing harmful pathogens and microorganisms present in the water. This compound provides a reliable method for ensuring the safety of drinking water, especially in situations where immediate access to clean water sources is limited. Its use is particularly beneficial in military settings where quick and effective disinfection is crucial for maintaining troop health and operational effectiveness.

While iodine tablets and boiling water are also methods for disinfecting water, calcium hypochlorite is preferred in many military scenarios due to its stability, ease of storage, and effectiveness against a broader range of contaminants. Filtration alone may not eliminate all harmful organisms and is typically used in conjunction with chemical disinfectants to ensure comprehensive water safety.
