There are some who feel that the purification of drinking water "in the field" is difficult, risky, and should only be handled by trained professionals. One such opinion states:

This is simply not the case anymore, as even the un-trained novice can make safe and healthy drinking water by using our portable purification units. In fact, the "NOAH SOLUTION" re-writes the rules on remote water purification. Our units were designed, engineered, and built to solve the very same problems as expressed above.

  • Purify All Types of Unsafe Water
  • Designed Specifically For Remote Areas
  • Systems Made Operational in Minutes
  • Simple Operation with Little / No Supervision
  • Easy Maintenance, Cost Effective
  • Comprehensive 4-Stage Purification Process

While the Trekker, Jungaleer and Nomad differ in capacity, all three use the same patented technology. In addition to visibly cleaning the water, they also methodically kill the bacteria and virus hidden to the naked eye. That's what sets the Nomad and Trekker apart from all other products on the market. We've combined filtration and Ultraviolet treatment, engineering them together into one cohesive process, creating water purification units that are completely portable.

FOUR STAGE PURIFICATION PROCESS
1. Pre-Filtration
     - Prevents large debris from entering the System
2. Sediment Filtration
     - 5.0 Micron Sediment Filtration
3. Carbon Block Filtration
     - Chemical removal and 0.5 Micron Filtration
4. Ultraviolet Treatement
     - 99.9999% Elimination of Bacteria / Virus
     - Ultraviolet exposure of 16,000 mw/cm2 or greater meets U.S. EPA guidelines

Pre-Filtration

The purification process starts with a pre-filter, screening the source water at the point of entry. In the Noah product line, the pre-filter screens are incorporated with the inlet hose. This is essential in preventing the system from becoming plugged with rocks, mud, feces and other large debris.

Sediment Filtration

The water passes through a sediment filter. Adding a sediment filter provides 5-micron filtration to extend the life of the carbon filter by removing unseen sediment that will prematurely clog the filter.

This would include the removal of:

  • Sand, Silt and Scale
  • Dirt and Mud
  • Other Suspended Solids

Carbon Block Filtration

The carbon block filtration process is actually comprised of two distinctly different procedures.

  1. Chemical Bonding: Uses activated carbon (sometimes called activated charcoal) which has a slight electro-positive charge added to it, making an even more attractive bonding agent to chemicals and impurities. When water is forced through the solid carbon block, it is forced to slow down and increase the amount of contact time with the carbon, allowing the carbon bonding to take place.
     
  2. Mechanical Straining: The carbon is compacted into a solid brick of material. Every molecule of water is forced through the microscopic pores of carbon, effectively straining out particle matter.

OTHER CARBON FILTRATION BENEFITS

  • Replaceable Cartridge - Easily Changed
  • Self-Clogging Cartridge - No Guesswork
  • Does Not Waste Water
  • Does Not Remove Beneficial Minerals such as Calcium, Magnesium and Flouride

Ultraviolet Treatment

Ultraviolet treatment is the final, and in most cases, the most important step in the purification process. After the carbon filter has cleansed the water, it is exposed to intense dosages of UV light. This exposure effectively destroys viruses, bacteria, fungi, algae and protozoa.

  • UV light destroys a microorganism by scrambling its DNA structure
  • The cells are rendered sterile and cannot reproduce
  • The cells are dead and no longer a threat

The table below lists many common microorganisms and the Ultraviolet dosage (in microwatts / cm2) required for 99.9999% destruction. All Noah products provide 16,000 microwatts / cm2 or greater of UV exposure.
