Water is a natural resource that should consistently be recycled and purified, and there are ways everyday tap water can be purified outside the common reverse osmosis system. These 3 options are also a more green approach to tap water purification.
1. A new concept of purifying tap water by gravity has emerged recently that requires little or no external energy consumption: purification though gravity. The only energy that is required in this method is whatever is needed to pump water to the top of its purification tank. From there, water is gravity-fed through a system of activated charcoal, which is simply processed carbon that it large and porous. This allows for absorption and filtration of impurities.
2. UV-A (ultraviolet) radiation, also known as solar power, can purify water as well. This process is also known as the SODIS process, and can be achieved using a regular water bottle or a specially designed water bottle that conducts solar power radiation quicker and more efficiently into the water, which helps disinfect it.
3. Nanotechnology, incorporated into filters, can also be utilized to make tap water purification more efficient. Nanotechnology, also used in water softener systems, not only separates silt and contaminates like a regular filter, but it also chemically reacts with other particles, such as metals, and allows clean water that is bacteria-free to pass through.
Without fail, the least time-consuming way to purify water is the traditional method of boiling it. One minute of boiling at a rolling boil can do the trick, though if you are more than 1 mile more above sea level, it is recommended you boil for around 3 minutes.
