Water is one of the essential elements for humans to survive. A person might be dead if he or she hasn’t had water in a week. Since our body consists of 70-75% of water, it becomes quite vital to pay attention to the water we are drinking. The quality can affect our health, and if the water we intake is not clean enough; it will do some harms to our health such as daytime fatigue, the most popular one nowadays.
How do we monitor on the quality of the water we are drinking? There is an easy and handy way to do, that is, water purifiers. Although most of the nations have water purification system, the quality of water is still a concern such as the toxic bacteria or heavy metals, damaging out health system day by day. From the traditional boiling purification, now we have not only purifiers but also purifiers with high technique- reverse osmosis.
Namely, reverse osmosis is a reverse process of osmosis. When the two liquid in different concentration is divided by semi permeable membrane, the liquid is usually move from low to high concentration. This principle is easily used in water purification. The water passes through membrane of reverse osmosis purifier, while salt and other ions may quickly rejected in the process. In this way, the permeate water finished.
