Abstract
A portable, personal advanced-oxidation water treatment system based on ozone and a catalyst such as titanium dioxide that can cycle and purify water to make it potable by removing organic contaminants. The unit can be used for long periods of time without having to replenish the active portions. The unit can be carried in a backpack or in a vehicle. Fresh water is typically loaded into the unit, and the unit is cycled until the water is pure enough to drink. A battery is used to produce ozone and to cycle the water through a reaction vessel and can optionally be charged with a small solar panel The unit can also be powered directly from a vehicle.
Claims19
A backpack worn, portable water purification system designed so that a single user can purify a quantity of water by putting into a tank, charging it with ozone gas and re-circulating it through a reaction chamber until potable, the system comprising:
- a backpack sized to be worn by a user;
- the water tank, a pump, a venturi and the reaction vessel all contained in the backpack, the water tank fluidly connected through the venturi to the reaction vessel;
- the reaction vessel fluidly connected back to the tank;
- an ozone generator also contained in the backpack producing ozone gas, the ozone generator being gas-connected to the venturi so that ozone gas transfers into the water though the venturi;
- the reaction vessel containing a reacting surface coated with titanium dioxide;
- the pump continuously recirculating water from the water tank into the reaction vessel and back to the water tank;
- a drain on the water tank constructed to allow a user to remove potable water from the water tank.
The portable water purification system of claim further comprising a solar panel to recharge the battery.
