Almost 85 percent of diseases and bacteria acquired by children are waterborne. This results from inappropriate water treatments that increase the risk of tuberculosis, meningitis and hepatitis B. This is why scientists and ordinary citizens have struggled to find ways to purify their drinking water in the simplest yet most effective ways. One of the most popular water purification systems today makes use of ultraviolet filtering. With the use of ultraviolet light, bacteria from the water is absorbed and altered to eliminate the risks of sickness in adults and in children.
Remove the labels of the four 2-liter polyethylene terephthalate bottles. Check whether the bottles have marks or scratches. Do not use bottles that are heavily damaged.
Rinse the bottles with tap water. Remove the caps and fill three-quarters of every bottle with tap water. Cover the opening of the bottle with your thumb and shake it vigorously for at least 30 seconds.
Replace the bottle caps after shaking. This will enhance the saturation of the oxygen in the water to make the purification more effective.
Screw the ultraviolet light bulb into the wall socket, placing it as high above as possible. Place your corrugated iron on the floor of the room, right in the path of your UV light.
Place the bottles right on the sides of the metal sheet, following its ridges. Raise one side of your metal sheet to a 45-degree angle to the ultraviolet light. Wait for six hours to allow the water to purify.
