How water is purified
Water is made up of hydrogen and oxygen molecules, which are microscopic, whereas most molecules that contaminate water are very large. To purify dirty water, it must go through a filtering process. During this process, large, unwanted molecules are trapped and smaller water molecules are able to flow through.
The water purification process consists of three stages: filtration, reverse osmosis, and advanced oxidation. In the filtration process, sophisticated filtering procedures are used to remove bacteria, parasites, and small solid particles. Next, in the reverse osmosis stage, any remaining chemicals, hormones, viruses and bacteria are trapped using a very fine membrane. Finally, advanced oxidation is used to further treat the water and guarantee its quality. Dirty water has to pass through these three stages before it is considered to be pure again.

Sleep deprivation – or SD, as it is sometimes known - is a common problem in the 21st century. While doctors recommend that we sleep seven to nine hours a night, many people try to get by with six hours or less. Insufficient sleep has a dramatic effect on the body, causing performance levels to drop to those of someone with a blood alcohol reading of 0.05. Sleep-deprived people also become vague, forgetful, and irritable and their relationships at home and work suffer.
The good news is that sleep deprivation and the problems it causes can be easily addressed. A single long night’s sleep can help people to feel better immediately, and two or three nights like this can bring about a complete recovery.
However, many people have forgotten how to get a good night’s sleep. To ensure that you do, it is important to change your evening routine. First, make the decision to go to bed between seven and nine hours before you have to get up the next morning – and stick to this decision. Try to go to bed at the same time each night. Next, avoid eating two hours before bedtime, and avoid stimulants such as coffee. Before going to bed, have a hot bath or a warm drink of milk. Finally, make sure that your bedroom is dark, as your body associates light with daytime and being active. These small, but significant changes will result in a better night’s sleep, and the end of sleep deprivation.
