An alternative to the UV filtration is solar purification which involves treating water with the ultraviolet radiation of the sun. The process involves filling a plastic bottle with water, shaking it to activate the oxygen and leaving it horizontally in the sunlight. This effectively kills bacteria and viruses present in the water, making it safe for consumption.
