When seeking to eliminate the threat of contaminants in your drinking water, to reduce the threat of even the smallest bacteria, a reverse osmosis water purifier is known as one of the best.
Originally designed to desalinate seawater for the U.S. government in the 1950’s, and used extensively on submarines and Navy ships, a reverse osmosis water purifier does not use chemical such as chlorine or iodine and does not require frequent filter changes or cleaning.
The secret behind the reverse osmosis water purifier is the size of its filtering ability. The human hair is about 1 micron, however disease causing bacteria is much smaller, typically between about .01 and .001 micron. A reverse osmosis water purifier utilizes layers of membranes, rolled into a cylinder with effective filtering to .0001 microns.
Filtration through a reverse osmosis water purifier is slower than other filters due to the size of membranes. For single-family home use, usually 50 to 60 gallons of water per day is needed and achieving that capacity depends on the length and number of the membrane sheets within the filter. Typically a larger quantity of shorter membranes allow water to pass through more quickly while fewer sheets of longer membranes may still increase the time it take to filter the water.
Flow Depends On Water Feed Supply
Other factors affecting the flow of water is its temperature and pressure pushing it through the reverse osmosis water purifier. Industry recommendations are for a water pressure of 50 pounds per square inch at 77 degrees Fahrenheit. Since most home water supplies do not fall into those parameters, reputable reverse osmosis water purifier suppliers will not guarantee a specific claim as the amount of water that will be available daily.
Another advantage of a reverse osmosis water purifier is the life of the membrane filters. Other types of water filtration systems require a new filter between two and four weeks, depending on the type and density of the impurities in the water. Most reverse osmosis water purifier systems have a self-cleaning ability that uses unfiltered water to wash over the membranes, vanishing collected impurities into its drainage system.
As a result, filter changes are not required as often as the collected impurities are washed down the drain and you are not trying to passes water through a filter that is already loaded down with contaminants. This also ensures that the water entering your system is free of impurities.
