Since 1939, Laboratorios Argenol has manufactured Silver-based products, whose antimicrobial properties whose antimicrobial properties are of great value in various fields, among which one of the most important ismicrobiological Water Purification.

Drinkable water

Nowadays, Colloidal-Nanocrystalline Silver is very frequently used in underdeveloped countries where it is necessary to purify water daily for drinking purposes.Our Silver Colloids such as Collargol, Proteinate, Vitellinate, Targesine and Targesina with borax are being used in this field.

Water purification can be carried out by:

-Addition of Colloidal Silver solution to the polluted water. Dose and treatment time can

-Water filtration through ceramic filters painted with Colloidal Silver solutions, such as those made by the NGO, Potters for Peace.

Every day there are more NGOs that send Colloidal Silver in small bottles to victims of natural catastrophes such as hurricanes and Tsunamis.

Swimming pools and industrial uses

The use of Silver as an alternative to,or in combination with,Chlorine in water disinfection is becoming increasingly important. Some of theadvantages of Silver over Chlorine are:

-Longer duration because Silver does not evaporate

-Non-toxic

-Greater effectiveness against a broad range of microorganisms (Bacteria Gram-positive, Gram-negative, Fungi, Yeasts, etc.)

-Faster bactericidal action.

-Does not produce organochlorides in contact with water.

-A smaller amount of Colloidal Silver than of Chlorine is needed to achieve the same effect.

Water purification can be carried out by:

-Water filtration through clay, sand and gravel in which Colloidal Silver has been deposited.

- Addition of Colloidal Silver to water.

Cooling towers

Silver has a strong bactericidal power.For this reason, it is useful in the disinfection of open or closed Cooling Tower circuits where Legionella propagates.Due to its effectiveness and the prolonged duration of its effects, Silver is an an important alternative in the prevention of the development of this disease-causing microorganism, in many cases fatal for human beings.

Water purification can be carried out by:

-Addition of Colloidal Silver to circuits.

-Slow liberation of Silver ions incorporated in inorganic and insoluble carriers.
