With all the enthusiasm for the reverse osmosis filtration systems, many people are taking an intelligent system must be able to offer the best water possible. Some want to investigate immediately, and others, perhaps even run out and buy. But the type of filtration systems available, which is actually a filtering system is the average homeowner should buy? Let's see how it works and how rates of safety standards ...
A reverse osmosis filter uses afine semi-permeable membrane within the device, with a discharge pipe to the device. The exhaust pipe is where contaminated water is filtered when ready, while the water "pure" through the membrane. High pressure is used to force the water through the membrane, leaving contaminants that are larger than a water molecule.
The advantage of the reverse osmosis system is that it is easy to filter out most organic contaminants, bacteria andHeavy metals ... and all this without increasing your electric bill, since none is used.
The disadvantages of the system are appalling. Not all impurities are smaller than water molecules allows membrane filtration to escape some of the smallest microbes to the depth of the water tank. It is known that chemicals such as pesticides and herbicides, both molecules are smaller than water molecules, so that the majority of reverse osmosis filtration systems can not and must notalone.
They must work in tandem with a carbon filter to keep those smaller contaminants out of your water. They are also slow, producing only around a gallon of water per hour, so the unit will also come with a storage tank, allowing it to keep working even when you aren't around to ensure you have an adequate supply.
The disturbing aspect for those that are environmentally conscious is that for every gallon of water you are purifying with a reverse osmosis filtration system, you are using up to four gallons. With water shortages a viable threat when river and lake levels drop, most do not want to waste such a valuable natural resource. It's scary to think that in making your water safe for consumption, you might be doing just that.
And last but not the least; the system's major defect is its inability to differentiate between what is good for your health and what is not. So while the pesticides can pass through into your glass of water, the minerals so essential for your body will be filtered out every time, leaving the water in an acidic form that actually harms the body tissues in the long term more than a bout of diarrhea would! In the end, it is your personal health which may cause you to choose something that does more than just give us fancy words and unsafe water, and rightly so.
