Humid air ozone generation

 

In OzA Series ozonizers a technology of generation of ozone out of humid air is implemented. Ozonizers of this series use an impulsive barrier discharge, which is specially adopted for humid air environments. The main problem that prevents proper functionality of the traditional corona discharge ozonizers - formation of the nitrogen oxides in the discharge chamber. This causes formation of the conductive nitric acid film on the surface of electrodes, which blocks the normal operation of the ozone generator and leads to a dramatic  performance deterioration. This leads to a necessity of use a special systems of preliminary preparation and deep drying of air in order to overcome this problem. Such systems are complicated and expensive enough, which presents a significant barrier to use the ozone-generation equipment in the relatively small purifiers. All ozonizers that were present on the market previously and were not equipped with air drying module, required a frequent maintenance and replacement of the discharge chamber that is actually became a consumable item, so to speak. Technical approach to the problem, used in OzA Series ozonizers, was made possible by the development of a new type of dielectric barrier discharge were pure oxygen gas is exposed to a plasma, which blocks the formation of nitrogen oxides and nitric acid film on the surface of electrodes. More detailed description of this technology can be found in the "OzA Series humid air ozonizers" section.

Technology of water purification with use of ozone stimulated coagulation in combination with ultrafiltration step and reverse osmosis. Modern techniques of waste water treatment and drinking water purification require a development of new efficient and energy-saving approaches. It is related with the fact that quality of the source water have degraded dramatically and new types of pollution have appeared, hence requirements for purified water of a good quality have become tougher. Traditional approaches that use a time-tested techniques such as coagulation, flotation, sedimentation, filtration through granular filters, etc. increasingly find themselves practically ineffective. Wastewater treatment according to established standards is particularly crucial prior to discharge them into fishery ponds, and in Russia this category includes almost any ponds. Quality requirements for waste water treatment is much higher in many ways than the quality requirements for drinking water purification and the practical impossibility of achieving of the results leads to the fact that the waste water does not treated at all and problem is solved by Russia's traditional way instead. Scientific research division of our company has developed a technology of waste and drinking water treatment that uses the ozone stimulated process of coagulation of organic and inorganic contaminants, which allows us to achieve results in many situations where traditional approaches practically do not work. The principle of method is the fact that salt of ferrous iron is used as a coagulant, which is oxidized by ozone. As a result of oxidation, the finest colloidal particles of iron oxide are formed and grabs the organic and inorganic contaminants. After removing these particles by the use of ultrafiltration membrane, it is possible to achieve a high degree of purification off the many difficult-to-remove contaminants. This technology that is described in detail in the "Industrial waste water treatment" chapter, is simple to use, economical and, what is most important, is efficient in cases when other, even more expensive methods are not working.

 

Ozone-ultrafiltration water purification technology

 

Application of ultraviolet light is safer, but not very efficiently due to the rapid emergence of salt sediments on the surface of the lamp that absorbs ultraviolet. The removal of these sediments requires constant use of chemicals, which is quite expensive and inconvenient.

Ozonizing is one of the most efficient technologies of water decontamination. The disadvantages of this technique are very large required doses of ozone and processing time for decontamination of the latent microorganisms, such as spores or cysts. In this case, the ideal combination would be application of ozone along with water filtration through ultrafiltration membrane. Ultrafiltration membrane entraps all microbial species and ozone prevents their reproduction on a clean wall of membrane.
