Microspiralfilters

The filter material was originally developed to purify water contaminated with radioactive waste products such as Cesium-137 (removed at a rate of 99,7%).

 

It also proved highly efficient against heavy metals and chemicals as well as bacteria and parasites. Several practical products for various applications have now been developed. The unique material attracts and captures nearly everything save the water and minerals. When the cartridge is filled with unwanted substances, it indicates that it needs to be changed.

Filtering using microspirals

How does the filter work?

The material works in four ways: illustrated to the right is the stage where only water molecules and minerals can fit through the spirals. Medical waste products and other chemicals are effectively trapped and can not be dumped into the water again even if an occasional increase of water pressure should occur.

An enhancement of the unique microspiral material is displayed below. It consists of micropores with a spiral structure. The pores of the standard filter used measures 0,05 - 0,1 μm. A bacteria like E.coli measures around 2 μm and a parasite like Cryptosporidium 5-8 μm. This makes it easy to understand why the microspiral material works as an efficient barrier against these dangerous organisms.

Types of filtration:

 

Mechanical (shown above), sorption and ion-change filtration.

 

To the left:

 

a) The material in the cartridge is positively charged (+). It has a surface of 500 m /g and all of the surface is active and is therefore more than 20 times as efficient compared to any other material. 

 

b) This electric field of the polymer attracts opposite charged viruses, bacteria etc .

 

c) Silver in the material suppresses growth of microorganisms.

(The silver, just like the rest of the filter material, is very stable and does not leak into the water).
