The need for an effective water filtering system has led to the development of several technologies that attempt to remove harmful elements such as chemicals and organic bacteria from water supplies.
The effect of these harmful elements on human health has been shown to be extremely hazardous over the long term, often resulting in serious health issues such as cancer.
Although humans have been using various methods for centuries to remove harmful elements from water, such as distillation, they were found to be less than practical when applied to larger filtering systems, such as municipal water treatment. A popular approach to water purification is known as reverse osmosis.
The process of reverse osmosis is founded in scientific truth, whereby the natural movement of water molecules can be used to screen out those elements that are of a different nature than water. Health through reverse osmosis can be obtained in this manner, as contaminants can be filtered out of the water supply.
This system of water filtering depends on the use of a semi-permeable membrane that consists of a grid of very fine pores. These pores are sized to be able to block the movement of those elements that are larger than water molecules as water is forced through the membrane.
The separated water molecules are then sent back into the original water source, free of contaminants.
Although the theory of obtaining better health through reverse osmosis is based on sound scientific methodology, there are aspects to this method that do not in fact fully remove some of the more complex synthetic chemicals that are used today, such as petroleum additives and pesticide compounds.
Many of these elements are actually smaller than water molecules, and will pass through the semi-permeable membranes used in reverse osmosis.
Additionally, those minerals that are found naturally in water that are essential to human health are inadvertently removed by reverse osmosis, as they are larger in molecular size than water. This can lead to serious health issues caused by mineral deficiencies.
Another impractical aspect to reverse osmosis technology is the amount of water processed versus the amount lost in the process itself. It has been found that the reverse osmosis process loses around 3 gallons of water to every gallon processed, which takes over an hour to obtain.
More recent EPA findings suggest that a water filtering system that uses activated carbon filters in a multi-media system to block contaminants is not only the most effective method of water purification, it is also the most cost-effective.
