Ozone, with the molecular formula O3, is a sky-blue fishy-smelling gas that is dark black in liquid form and blue-black in solid form. Ozone mainly exists in the lower stratosphere 20 kilometers from the earth's surface in the ozone layer. It absorbs, blocks and weakens short-wave ultraviolet rays that are harmful to humans, preventing them from reaching the earth.

Toxicity

When the concentration of ozone in the environment is high, but also a kind of environmental pollution gas, it is one of the greenhouse effect gas, kill bacteria at the same time also constitute damage to human cells, in the static electricity area, next to the printer, should pay attention to ventilation, to avoid the toxic effects caused by the ozone concentration is too high.

However, ozone disinfection technology has been widely used in water treatment, air purification, food processing, medical, pharmaceutical, aquaculture and other fields. Ozone technology is gradually mature, ozone is also slowly known to people, because of its strong disinfection ability to replace the conventional disinfection is applied to various fields.

Ozone for Air Purification

Ozone has the ability to kill bacteria and viruses contained in the air, has the function of reducing dust, makes the air fresh and natural, and plays a role in eliminating fatigue and refreshing the brain.

Ozone for Fruit Vegetable Storage and Preservation

Ozone can inhibit the expression of some genes and reduce the activity of aminocyclopropanecarboxylic acid synthase and aminocyclopropanecarboxylic acid oxidase, thus reducing ethylene biosynthesis and delaying the ripening of fruits and vegetables. In addition, ozone treatment significantly reduces cell wall swelling, inhibits pectin and neutral sugar dissolution and cell wall degradation enzyme activity, thereby reducing fruit and vegetable pulp softening and cell wall decomposition.

Ozone for Disinfection of Production Utensils, Work Clothes

Food processing, cold beverages, biochemical pharmaceuticals and other sectors of the work clothes disinfection requirements are very high. Generally often used ultraviolet light irradiation method, because the light wave directly to the part of the disinfection effect, the irradiated area is very small, the actual effect is very poor. The use of O₃ on the work clothes disinfection is an efficient, economical and simple method.

The shelf life of mineral water depends on the complete killing of microorganisms, and the commonly used method of filtration plus ultraviolet disinfection is difficult to meet quality standards. Ozone sterilization becomes the method, not only can completely kill microorganisms, but also can remove iron and manganese, soluble salts in the water, preserving the beneficial carbon and oxygen compounds.

Ozone for Product Decolorization and Bleaching

As a strong oxidizing agent, ozone can also function as a decolorizing agent in the food industry. In the sugar industry, the current common method is to add sulfur dioxide as a clarifying agent, but this method leads to sulfur residue in the finished product and has great limitations in use.

Ozone can be considered as an alternative to sulfur dioxide for testing, controlling the ozone treatment conditions to achieve the desired decolorization requirements without generating toxic chemical residues. In addition, ozone can also be used in the bleaching of whey protein, the traditional bleaching method of whey protein is to use hydrogen peroxide or benzoyl peroxide, but this method may cause changes in the flavor of whey powder, under certain conditions, ozone can achieve the same bleaching effect as hydrogen peroxide.

Some occasions in the use of ozone disinfection, the need to use ozone detectors have real-time monitoring of ozone disinfection concentration, in order to achieve the best concentration of disinfection, and after the disinfection should be used to detect the residual concentration of ozone using high-precision ozone detectors, to prevent residual ozone hazards to personnel. As the concentration of ozone needs to be controlled within a certain range, with the continuous promotion of ozone disinfection, ozone sensors used to measure the concentration of ozone in the air has tended to improve.

Ozone detection, currently still rely on ozone detectors, ozone detectors built-in electrochemical principle of high sensitivity ozone sensor, with good linearity, high sensitivity, low power consumption and other characteristics. Built-in temperature sensor, temperature compensation; at the same time with digital output and analog voltage output mode, easy to use.
