Reverse Osmosis

Typical contaminant rejection rates range from 85% to 95%, some of the highest quality reverse osmosis membranes on the market like that of which is used in MiraculeWater systems have a contaminate rejection rate of about 99%+ and a gallon of highly treated water can usually be produced from two to five gallons of raw water in a standard reverse osmosis system, depending on the initial quality of the water. Maintenance involves the replacement of the RO membrane cartridge every one to three years, and the carbon filter cartridges two to twelve times per year depending upon the source water and the amount of use or volume of water run through the machine. Due to the special Proprietary technology used to prevent biological elements from growing in and feeding on the membrane in MiraculeWater systems. Membrane replacement times can be extended to as much as 7 years. This extended replacement time is based upon the length of time a single person drinking one gallon per day would take to exhaust the extra filtering unit that is built into the Membrane's which MiraculeWater enhanced mineral water machines use under average conditions. No other company has these exclusive features.

RO is effective for the reduction of a broad range of health and aesthetic contaminants, though it is typically not used for the reduction of biological pathogens. Most RO systems also incorporates an activated carbon filter, which can provide added treatment for the volatile organic compounds (VOC's) not treated by the membrane itself. Most MiraculeWater systems employ 4 activated carbon filters to reduce the volatile organic compounds to normally undetectable levels.

Another Big Problem with most standard Reverse Osmosis Units.
Bacteria and other biological pathogens can damage an RO membrane by eating there way through it, very few RO systems on the market use filters that prevent biological pathogens from reaching the membrane. All MiraculeWater systems use the best filters available to prevent biological pathogens from reaching the membrane. Then MiraculeWater corporation uses another advanced proprietary technology to prevent bacteria from eating there way through the membrane. Most companies care only about the profit from there sales and put the cheapest filters available in there RO units, we at MiraculeWater spend the extra money for the best filters for all of our units. The portable, house under sink, and cooler's that MiraculeWater makes contain 2 filters built to remove biological pathogens before they reach the membrane. The first is rated at a removal level of 95% and of the 5% that makes it's way past it. The next filter is certified to stop 99.9996% of E. coli that reaches it. It is NSF certified Standard 53 in Cyst reduction including Cryptosporidium and Giardia. It also has a NSF Standard 42 Chlorine, Taste & Odor Reduction rating. It is the most cost-efficient means of combining the performance of a ceramic candle and a activated carbon filter into one filter that we have found on the market. It takes a filter with a nominal filter rating of 0.2um* and a absolute rating of 0.5um** to meet this requirement.

NOTES
Chlorine capacity is the estimated capacity in gallons during which the filter will remove > 95% of influent free available chlorine (2 ppm) when operated at a given flow and has been tested using the NSF Standard 42 protocol for chlorine reduction.

Nominal particulate rating (0.2µm) is for >85% of a given size as determined from single-pass particle counting results.*

Absolute particulate rating (0.5µm ) is for >99.9% of particles of a given size as determined from single-pass particle counting results.**

*Nominal Filter Rating: Filter rating indicating the approximate size particle, the majority of which will not pass through the filter. It is generally interpreted as meaning that 85% of the particles of the size equal to the nominal micron rating will be retained by the filter. (WQA Glossary of Terms, Third Edition, 3-97).

**Absolute Filter Rating: Filter rating meaning that 99.9% (or essentially all) of the particles larger than a specific micron rating will be trapped on or within the filter. (WQA Glossary of Terms, Third Edition, 3-97)


It should be remembered that this brief description of Reverse Osmosis water treatment technology is only intended to provide an overview of how each technology can be applied to solve a water contamination problem. The advice of a MiraculeWater Certified Water Professional or Certified Sales Representative should be sought when looking for a specific treatment solution.
