Oasis-3 Portable Solar Powered Water Purification System

Our Oasis-3 water purification system is currently being developed. We expect to launch the product by Q2 2017. Please join our mailing list for updates including pricing and availability. Thank you.

The Oasis-3 water purification systemThe Oasis-3 water purification system is designed to rapidly provide clean, safe drinking water anywhere in the world.

The Oasis-3 can produce 2 gallons (7.5 litres) of potable water every minute, or up to 2,880 gallons (10,900 litres) per day using a comprehensive 5-stage filtration process.

The Oasis-3 is a robust, portable, self-contained, solar-powered water purification unit that works by pumping water from a lake, river, stream or virtually any other fresh water source, and passing it through a series of filters to remove sediment, protozoa and chemicals, and kill bacteria and viruses.

The unit can also be powered from multiple sources including internal battery, solar, external DC or AC, making it truly versatile. See all available configurations.

Following a disaster, access to clean, safe water for drinking, cooking and cleaning is vital where normal supplies have been disrupted or destroyed. Without access to clean water, people are exposed to an increased risk of communicable diseases such as diarrhea, hepatitis, leptospirosis, and cholera. Based on the SPHERE Minimum Standard of 15 litres per person per day, the Oasis-3 can easily provide enough clean water for about 550 disaster victims.

Designed and manufactured by AidGear in USA, the Oasis-3 contains everything needed to sustain operations, including the water pump, military-grade foldable solar panel, hoses, spare filters, fittings and fixtures. Each unit is manufactured from 80% American made parts and sold with a 1-year warranty and technical support.

How It Works...

Water is pumped from virtually any fresh water source including streams, rivers, lakes, ponds, wells, and flood water. A series of filters are used to produce safe, clean, drinking water:

  • Inlet screen - A coarse metal screen removes large debris such as rocks, leaves and other objects.
  • Filter #1 - A washable 80-mesh (177 micron) screen protects the pump by removing coarse sediment including sand and organic material.
  • Filter #2 - 5 micron sediment filter removes fine suspended particulates such as sand, mud and other suspended solids.
  • Filter #3 - A choice of 0.2, 0.45, or 1 micron "absolute rated" membrane filter removes fine sediment, hair, dust, viruses, bacteria, protozoa and spores.
  • Filter #4 - 10 micron activated carbon filter removes chemicals, tastes and odors.
  • Filter #5 - Ultraviolet (UV) light scrambles the DNA of bacteria and viruses rendering 99.99% of them sterile.

A final, optional step, is to add purification tablets to ensure residual disinfection within water storage containers occurs up to the point of use.
