subject: How Does a Water Purifier Work and Which is The Best Type To Protect Your Health [print this page] Due to advances in filtration technology, today there are some very effective water purifiers around. However, many of the popular ones are not effective so let's see how they work.
How does a water purifier work?
The two main types are reverse osmosis (RO) and carbon block filters.
The RO systems expose water under pressure to a semi permeable membrane with a very fine pore structure. Because most inorganic contaminants have a larger molecular size than water, the membrane rejects these, essential trace minerals and a large proportion of the water.
Apart from wasting a lot of water, the harmful synthetic chemicals like pesticides and prescription drugs are able to pass through as they are molecularly smaller than water. In addition the important trace minerals like calcium and sodium which you need in your supply are removed.
Regarding the amount they discard, an reverse osmosis system that delivers five gallons of treated water a day may discharge forty to ninety gallons of wastewater per day to the system.
The next type is a carbon block filter.
This uses the latest technology to not only physically remove contaminants but also to chemically bind them to the filters surface. This means all the harmful contaminants are removed, including the synthetic ones, with the best systems able to remove 99% of them.
Look for a sub micron filter and ion exchange for the most effective ones and a dual process also helps to increase the removal rate.
These carbon filters also leave in the essential trace minerals and do not waste water.
It is really getting to be a necessity in most areas now to have some kind of home filtration with thousands of toxic chemicals entering the supply.
Some of the latest samples from around the US found at least two types of weedkiller in 90% of the samples and traces of others like lead and chlorine.
Chlorine is one of the most important chemicals to remove as it reacts with other toxins in the water to form deadly THM's which are carcinogenic.
Now you know the answer to, how does a water purifier work, you can hopefully now make a more informed decision and find the best type to protect your family's health now and in the future too.
