GEIZER company is one of the leaders of Russian water market. For more than 15 years GEIZER has been involved in development and manufacture of water filters for domestic and industrial application. Our technical experts are highly experienced in industrial water treatment and water conditioning systems including sewage treatment.

Our scientific staff has greatly contributed to success of the company. New materials and new technologies have been patented in 16 countries.

The main advantages are as follows:

• The unique filtering material Geizer (ion exchange microporous polymer) is the only material which can remove chlorine, iron, heavy metals, organics, carcinogens and viruses including hepatitis;
• The filtering material Geizer changes structure of calcium carbonate in hard water. That allows customer to reduce scale and decrease the risk of urine deposits in kidney;
• Geizer filter can be regenerated even at home, which makes its service very cheap;
• Damfer material is the base for unique domestic filter. It not only removes rust but also dissolves iron;
• Mineralizing element was designed to obtain clean water with an optimal mineral composition (iodine, calcium, magnesium, fluorine);

Purification of drinking water

Filtering elements made of SGS-polymer (SGS-8) are used in disposable filters for purification of drinking water. Filtering properties of a material are determined by processes of ionic exchange, sorption, and by sophisticated labyrinth-porous structure. Ionic exchange and sorption enable the material to delete the dissolved chemical impurity (iron, heavy metals, salts of hardness, radioactive elements). All the particles over sizing external pores of a material are mechanically filtered on a surface and in a subsurface layer. Advanced interior surface provides for higher sorption ability as compared with other sorbents (activated charcoal), which results in the effective removal of active chlorine and organic compounds. Water is not running straight through a material, but is following an extremely twisting way similar to a labyrinth, therefore the probability of chemical interaction of the dissolved impurity raises due to exchange interaction and sorption. Such as interior structure completely expels occurrence of strained harmful impurity through a material into purifies water, which is possible at a direct configuration of the internal channel especially after sharp increase in pressure of purified water.

The majority of bacteria and viruses have elongated shape (from 10 to 500 microns) so that are getting entangled in twisting channels of a material. In the process of manufacture, silver could be embedded into a material to suppress reproduction of the detained microorganisms. In the course of operation of the material, the number of working channels decreases gradually resulting in downward purified water head. Accordingly, its reduction to minimal comprehensible level suggests necessity of regeneration or cartridge replacement. Restoration of filtering properties is achievable by simple domestic methods. Besides, the filtering material has a unique property - water "quasi-softening" - reduction in hardness of purified water and change in the crystal structure of salts of hardness (calcium and magnesium carbonates), formed on heating elements as a scum, which does not deposit, but decays quickly and is washed off with water. Under hardness up to 4.5, the deposits do not drop out at all.

The efficiency factors of water purification with SGS-polymer are shown in the Table.
