Reverse osmosis is one of the most commonly used methods for desalinating seawater into drinking water. Many countries are now relying on seawater as a source of drinking water due to the lack of clean water from other sources. This happens because of environmental factors such as drought, flood and sea water level rising. Due to these problems, many reverse osmosis plants have been set up throughout the world. Currently, there are more than ten thousand desalination plants worldwide.
One of the benefits of reverse osmosis drinking water is that it does not have any lead. Leads can cause various types of health problems including high blood pressure, and damage to the nervous system, and reproductive organs. Reverse osmosis water is ideal for patients who have just undergone chemotherapy since they have weak immune system and cannot drink water that is not filtered properly.
Reverse osmosis water is clean from germs, bacteria and parasites. It does not contain dangerous parasites such as the cryptosporidium that can cause diarrhea. It is suitable for people with heart disease because i99% of the bacteria has been eliminated through the RO water filter.
Reverse osmosis system involves a desalination process where the salt are removed from the water. Salt is filtered away from the water with the use of semi permeable membrane. Therefore, reverse osmosis water contains no sodium and is suitable for people who suffer from kidney disease. Naval ships often use reverse osmosis system to filter the seawater so that their crew have clean water to drink.
The semi permeable membrane has about the same thickness as cellophane. Basically, anything that is larger than the water molecules will be filtered out from the semi permeable membrane so you can expect the water to be free from unhealthy contaminant such as arsenic, organic chemicals, sulfur compounds, selenium, and mercury. The fluoride is also removed from the water through the reverse osmosis process. Fluoride may be good for protecting the teeth from cavities but too much of the minerals can cause some negative side effects on the body. The impurities that are filtered from the semi permeable membranes will be flushed away.
The water filter in the reverse osmosis process can last for a long period of time without having to change frequently. The water filters are made from environmentally friendly materials. No chemical is used in the process of the RO water filtration. Anything that can cause a bad odor to the water is removed. You will find that reverse osmosis drinking water has a fresher taste. Bad taste in water is usually due to the chemical residues. It costs lesser to produce it and give you more value per gallon.
Some people claim that reverse osmosis is unhealthy because it is devoid of minerals such as calcium and magnesium. However, many respected water authorities have pointed out that this is a small issue and does not cause any health concern for people who are healthy. The small amount of minerals that are absent in the water can be replaced with consumption of food that contain these minerals in your diet.
