What is the purification time for a canteen of water when using Calcium Hypo chlorite?

The purification time for a canteen of water using Calcium Hypochlorite is indeed 30 minutes. This process involves adding the appropriate amount of Calcium Hypochlorite to the water, which acts as a disinfectant, effectively killing harmful pathogens and bacteria that could potentially be present in the water source.

The 30 minutes wait time is crucial as it allows the chemical sufficient time to properly disinfect the water, ensuring it is safe for consumption. This duration is based on the recommendations of health guidelines which help ensure a high level of efficacy in the disinfection process. Neglecting to wait for the full purification time could result in incomplete disinfection, making the water potentially unsafe to drink.

Understanding this purification process and time is essential for maintaining health and safety standards, especially in field situations where clean water is vital.
