How Do Reverse Osmosis Water Filters Work?
Reverse Osmosis Water Benefits
Hey, we have all read articles or seen on the news about water problems which cause health issues in the family. Maybe it’s time to consider getting our ass in gear and safe guarding our own family, starting off with the water supply. So let’s read on some more.
There are several water purifying methods that have been used by filters: mechanical, chemical, solar, and reverse osmosis. Of all these techniques, reverse osmosis is the most popular and can be said to also be the most advanced.
Osmosis simply means a water molecular motion through a semi-permeable membrane, like cell walls, from an area with little concentrated solute to another with a high concentrated solute.
Reverse Osmosis Water Filter
A reverse osmosis water filter works by squeezing the water by a 0.0001-micron half-permeable membrane, wherein it eliminates various molecules and ions from solutions through excess osmotic pressure. The reverse osmosis process is vital because it eliminates salt from the water. When salt enters the human body, it can eliminate water inside through the osmotic process, resulting to dehydration and even death.
Reverse osmosis, also known as Ultra-Filtration, was created in the 1950s through a U.S. government backing as a way of converting seawater into drinkable water. Since then, the process has been applied in bottled water, and manufacturing purposes.
Benefits Of Reverse Osmosis Water Filter
Looking at the benefits of reverse osmosis water filter systems, the process uses very small openings of membranes through which water can move. Organic compounds like salt and other natural minerals are contained within the membranes due to their larger molecular structure than water. The openings can stop the flow of bacteria and other harmful micro-organisms, which eliminates contamination that can cause deadly diseases like cholera.
There are some minor downsides of reverse osmosis water filtration. The process has some limitations in filtering water. The membranes cannot contain particles with smaller molecular structures like pesticides and herbicides, which contaminate water near agricultural and gardening areas. Because of this problem, carbon filters are designed to complement reverse osmosis by containing the remaining particles.
The reverse osmosis process also removes natural minerals. However, it is a myth to say that minerals in drinking water are beneficial. For sure certainly some of the minerals present in water such as calcium and magnesium can be beneficial, but there can be any number of toxic chemical such as arsenic and chromium. One often asked question is does reverse osmosis remove chlorine or fluoride? No water filtration systems can differentiate between “good” and “bad” minerals in the water. The vast majority of minerals our body needs comes from the food we eat, and not from water.
Lastly, the reverse osmosis water filtration process roughly requires a ratio of 3:1 to produce filtered water, ie: 3 gallons of unfiltered water to produce 1 gallon of filtered water. If live in an area where your water supply is limited, one of the other water filtration systems is probably a better idea.
To wrap this article up, now you’ve seen the basis of what you need to be doing, it’s time to decide do you want to go for the best water filter for faucet or step up a level and opt for a whole house reverse osmosis purchase instead?
