Water One Inc: Premium Bottled Water

Our 10 Step Process Includes

  1. Pre-filtration to remove sediment and particles
  2. Softening to remove hardness causing minerals
  3. Carbon filtration to remove objectionable taste and odor as well as any organic chemicals that may be present
  4. Reverse osmosis to remove 95 percent plus of dissolved solids
  5. Demineralization to remove remaining minerals and bring the water to zero parts per million of total dissolved solids
  6. Ultraviolet purification to make sure our water stays virtually free of microbes
  7. Storage/recirculation to begin the production process. Water is continuously freshened with ozone, a naturally occurring substance close to oxygen in molecular structure. Ozone controls microbial growth without the undesirable byproducts always associated with chlorination
  8. Ozone purification residual to ensure freshness whenever a new bottle of water is opened
  9. Final bacteria filtration before bottling. This is the time when food grade minerals can be added to enhance taste
  10. Washing, sanitizing, and bottling
