The pura vida h2o water purification process |
|
pura vida h2o products contain a multi-stage filtration and purification system that are designed to operate using existing municipal water supplies. The system is capable of absorbing or rejecting nearly all contamination. In addition these Water Stations have UV illumination or Ozone sterilization systems within them providing a biological barrier. Pura Vida h2o refill stations provide increased protection against any contamination or biological threat that may be in the existing water supply, protecting the public while also reducing carbon footprint. The multi-filtration process consists of the following stages: 1. The process starts with a sediment filter used to reduce the solids that are not dissolved within the water. These filters are usually about 1 micron(the human hair is about 70 microns). The primary objective in this stage is to allow the lowest amount of particles to pass through so that the next stage, carbon filtration, can remove contamination. 2. The carbon filter acts in two ways, first it acts as a filter removing any remaining particles while the second stage removes contamination. Carbon's effectiveness to absorb contamination is identified as an ultra-filtration filter which has a pore size of approximately 0.01 microns. The Center for Disease Control has provided guidelines based upon the filtration type and the size of the filter. Carbon is effective in providing clean pure water by absorbing over 97.5 % of most contaminates and is the first stage of a thorough purification process designed into these water stations. 3. The next step in the process is reverse osmosis. Reverse Osmosis is the most effective way to remove contamination and biological threats. Reverse osmosis (RO) is a filtration method that removes many types of large molecules and ions from water by applying pressure to the water when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure water is allowed to pass to the other side. Pura Vida h2o Water Stations have large RO units which will reject any contaminates. According to The Center for Disease Control, Reverse Osmosis Systems are very effective in removing bacteria (for example: Campylobacter, Salmonella, Shigella, E. coli) It is very important to understand that the water systems that pura vida h2o utilize are thorough filtration systems that are effective in removing harmful contaminates and biological threats. 4. pura vida h2o units come with a second carbon filtration stage that polishes the water purification process even further, ensuring only clean pure water is allowed on to the fifth and last stage of purification. 5. As a final stage, the pura vida h2o systems use either an active ozonation or UV light process to sanitize the water prior to dispensing. This removes any biological activity that may have been present after the purification process. According to the CDC these processes are effective in removing protozoa, bacteria and viruses from the water. |
