[content] => High-concentration ozone water is called "universal water" in Europe. [**]s a commonly used fungicide in wine production, it has become more and more common. It is one of the strongest oxidizing agents currently known to be available, and it is an efficient broad-spectrum fungicide. It can oxidize and denature the protein shell of bacteria, fungi, etc., and kill bacterial propagules and tooth cells, viruses, fungi, etc. Ozone has a killing rate of more than 99% for common E. coli, Streptococcus faecalis, Staphylococcus aureus, etc., and can also kill hepatitis virus, cold virus, etc. The ozone water machine uses air and water as raw materials and uses a 220V power supply to produce 10-15ppm high-concentration ozone water immediately.
1. Sterilization and disinfection:
(1) The food factory needs to carry out over-flow immersion sterilization on the surface of raw materials and other objects to form a sterile raw material surface (the packaging container can be sterilized by contacting with high-concentration ozone gas). For example, fruits, etc. can be sterile after being washed and can be made into concentrated juice.
(2) During the processing of aquatic products—before freezing and packaging, high-concentration ozone water spray sterilization or over-flow immersion sterilization has achieved perfect control of the hygiene indicators of aquatic products, avoiding the use of chlorides to bring residual chlorine Exceeding the standard problem.
(3) In the production process of liquid food processing (such as beverages, juices, etc.), high-concentration ozone water can be used for soaking and rinsing of pipelines, production equipment and containers, so as to achieve efficient sterilization. Bacteria and viruses on the surface of pipelines, equipment and containers are washed and killed, which is very simple and trouble-free. That is to say, there will be no dead angle, and the discharge and residue of harmful substances caused by the use of other chemical disinfectants are avoided, while ozone has no residue and secondary pollution.
(4) It can be widely used in hotels, hotels, and government canteens to sterilize tableware, fruits and vegetables; and to sterilize children's toys and the surface of objects.
2. Pesticide degradation: It can be widely used in public dining halls, fruit and vegetable processing plants, food processing plants, etc. to remove harmful substances such as pesticides, fertilizers, and food additives.
3. Water treatment: It can be widely used in algae prevention and sterilization of industrial water, sterilization and disease prevention of aquaculture water, deodorization, decolorization, sterilization and other processes in sewage treatment.
4. Food preservation: It can be widely used in the process of storage, preservation and disinfection of raw materials and finished products in the production and processing of refrigeration plants, food processing plants, livestock slaughter plants and other units.
Ozone is a strong oxidant, which can effectively disinfect, decolorize, deodorize, improve water taste, remove organic matter and reduce COD when used in sewage treatment. Therefore, in recent years, the technology of ozone and its combination with other means to treat various sewage has been developed rapidly.
Ozone permeates everywhere, without dead ends. Ultraviolet rays have a bactericidal effect only when they irradiate the surface of objects and reach a certain irradiation intensity standard. Food workshops are generally relatively tall, so that the intensity of ultraviolet radiation is far from enough, especially when the distance is long, and the radiation produces a large dead angle, such as the lower part of the processing chopping board. Ozone is a gas with strong permeability, good diffusivity, uniform concentration and no dead angle.
Due to the strong oxidizing properties of ozone, once it is mixed with water, ozone first reacts with some reducing inorganic substances that are easily oxidized in the water, and then reacts with some organic substances, causing the organic substances to degrade to varying degrees and become simple pollutants. Organic matter is further completely oxidized into carbon dioxide, which reduces the chemical oxygen demand (COD) value of water.
What is the concentration of ozone water to achieve the bactericidal effect?
Water treatment ozone concentration sterilization requirements:
The solubility of ozone in water applications is between 0.1mg/L and 10mg/L. The low value is the minimum concentration required for water disinfection and purification, and the high value is the achievable concentration value of "ozone water disinfectant". Ozone purification of tap water, the international conventional standard is the solubility value of 0.4mg/L, keep it for 4 minutes, that is, the CT value is 1.6.
The concentration of residual ozone in the water is kept at 0.1-0.5 mg/L for 5-10 minutes to achieve the purpose of disinfection.
The disinfection and sterilization of ozone water is rapid, and the disinfection effect occurs in an instant. Once the concentration of ozone in clean water reaches 0.5 to 1 minute, bacteria will be killed, and when the concentration reaches 4mg/L, the inactivation rate of hepatitis B virus will be 100% within 1 minute.
Bottled water treatment should reach the ozone solubility value of 0.3~0.5mg/L, and the addition of ozone should meet the generation amount of 1m3 water 2gO3. [**]ccording to practical experience, when the concentration of ozone generation is higher than 8mg/L, it is easy to reach the concentration.
