Working in cooperation with leading scientists and laboratories, NECON* has been able to give a new meaning to the century-old principle of electrophysical water purification.

We have spared no efforts to ensure that our claim "100% free of chemicals" is met.

With the use of innovative electrode materials and configurations, we have been able to overcome the problems of the fluctuation of pH values and the related formation of limescale.

Analytical data available for the international projects carried out by NECON GmbH in the public swimming pool sector show that our system produces drinking quality water.

And what water could be better for bathing than pure drinking water?

The NECON system consists of a state-of-the-art microprocessor-controlled electronic unit and the patented disinfection electrodes.

The water to be purified passes through a special treatment cell where it is exposed to the electrodes. These are activated by a low, precisely controlled direct current. The electrodes release copper ions (Cu++) and silver ions (Ag+). A large proportion of these ions accumulate in the quartz sand of the filter, so that this, with its extremely large surface area, acts as an additional disinfection cell and no bacterial foci can be formed in the filter. A further portion of these ions also pass into the pool with the water flow, where they develop their anti-bacterial and algaecidal effects.

Several studies conducted by major universities have shown that copper and silver ions are extremely effective purification agents. When copper and silver ions are released into the water, these surface-active cations act as potent natural disinfectants. In only fractions of seconds, the copper and silver ions with their positive charge form electrostatic bonds with the negatively charged areas of the cell walls of microorganisms. When these bonds are formed, the permeability of the cell wall is altered to such an extent that the normal nutrient uptake of the microorganism is impaired.

Once copper and silver penetrate an algae cell, they attack the sulphur-based amino acids in the cell proteins, which the cell requires for photosynthesis. As a result, photosynthesis is prevented and the cell dies.


Silver and copper irons form electrostatic bonds, which inactivate the germ cells in fractions of seconds and the cell dies.

For this reason, electrophysical water disinfection is one of the most effective alternatives to use of the standard "chemical warfare".

Other advantages are that it provides natural, odourless, soft and skin-friendly water which is ideal for children and in health care.

It has already been known for centuries that silver destroys bacteria and viruses, even those which are resistant to chlorine. Silver sulphate is frequently used in the antibacterial treatment of burns and open wounds and is also used to protect the eyes of newborn babies from infection.

As a trace element, copper plays a vital role in human metabolism. Copper is essential to the activity of many proteins and enzymes. It promotes the formation of skin pigments and has important functions in bone metabolism and in the central nervous system. As the body is not itself capable of producing copper, it must obtain copper from nutrients (such as vegetables, wholemeal bread, nuts and oats). Only a low number of copper ions are normally taken up by the body from drinks and beverages. The level of copper required for swimming pool disinfection and to prevent formation of algae is between 0.5 and 0.7mg/l. The specified upper concentration of copper in the German drinking water regulations is 3 mg/l. Any superfluous copper ions taken up by adults are not accumulated, but are eliminated from the body.

However, the most important advantage of copper and silver ions is that they are retained in the water and continue to provide protection by purifying the water completely without the use of toxins over the long term. Even after the filter system has been switched off, this depot effect persists for several months. Thus, constant adjustments and permanent monitoring, which require continuous supervision, are unnecessary.

The NECON water purification system is easy to operate and requires minimal maintenance. It has been demonstrated that copper and silver ions eliminate Cryptosporidium, E. coli, the cholera and legionnaires' disease pathogens and many other species of bacteria and viruses. This water disinfection technique can be used in practically all situations in which it is necessary to continually ensure freedom from contamination with bacteria, viruses and algae. The NECON system has already been installed in thousands of swimming pools and whirlpools.
