Description
s , PORTABLE DEVICE FOR WATER TREATMENT
FIELD OF THE INVENTION
The present invention relates to a device for purifying water and more particularly, relates to a portable water purifier.
BACKGROUND OF THE INVENTION
The problem of purifying water exists the world over. Inherently, most available water cannot be used for drinking or other human consumption without going through purification.
For large urban areas, the treatment of water for human use is done at centrally located facilities. The treatment steps are well known in the art and are practised worldwide.
However, outside of urban areas, the treatment of water is far more problematic.
While the water can be treated in situations where there are enough residences or demand in a centrally located area, the same is not true in extreme rural areas and particularly so in poor countries. The problem is widespread and there have been solutions proposed.
Generally, these solutions include the use of portable water purifiers.
While some portable water purifiers function in a manner to properly treat the water, many do not.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a portable water purifier which is designed to treat all different types of polluted water and to present a safe drinkable product at the discharge end of the treatment.
According to one aspect of the present invention, there is provided a portable water purifier comprising a housing, an inlet conduit, a first filtration station, a pump for pumping an aqueous fluid through the inlet conduit and through the first filtration station, a second filtration station, a magnetic treatment station wherein the magnetic lines of flux are angled with respect to the flow of the water, a UV station, and a discharge conduit.
According to a further aspect of the present invention, there is also provided a method for purifying water comprising the steps of passing water to be treated through a first filtration station, pumping the water through a second filtration station, subsequently pumping the water through a magnetic treatment station wherein the magnetic lines of flux are angled with respect to the flow of the water, and subjecting the water to an ultraviolet treatment.
In the above preferred embodiment, the water to be treated goes through a number of steps. Initially, the water is subjected to a physical filtration step to remove physical particles therefrom.
A pump is utilized to direct the water as required. The pump is preferably mounted within the housing and is a DC powered pump.
The water is then subjected to a second filtration operation. The second filtration operation preferably comprises a filtration media formed of KDF particles.
Preferably, the KDF water filter media are utilized in conjunction with granular activated carbon. The KDF media protect the carbon bed against contamination by bacterial growth.
The oxidation reduction process operates wherein a combination of copper and zinc particles creates an electro-chemical reaction. During this reaction, electrodes are transferred between molecules and new elements are created. As explained by KDF , some

Some heavy metals such as copper, led, mercury and others plate out onto the medium surface and thus are effectively removed from the water supply.
Subsequently, the water is subjected to a magnetic treatment wherein the water is passed spirally around a plurality of magnets such that the lines of flux form an angle with respect to the direction of flow of the water.
Finally, the water is subjected to an ultraviolet treatment, the ultraviolet station preferably being powered by 12 volt DC.
The system preferably includes a rechargeable battery which is powered by a suitable solar panel. Naturally, other arrangements for supplying power could be utilized if such power is locally available.
The systems of the present invention can be utilized in many situations. Thus, when large scale natural disasters happen, water is one of the very first priorities and the system of the present invention allows one to obtain drinkable water locally.
Preferably, the system would be housed in a military grade shock resistant non corrosive case. The system can deliver up to 60 gallons per hour. The source of the water may be any lake water, river water, swamp water, wetlands, etc. The flow would preferably be in the range of one gallon per minute.
