[content] => Ozone machines can be applied to many industries, and drinking water treatment is one of them. During the transportation of drinking water, it may be polluted from air, pipelines, packaging materials and other aspects. In order to ensure the health of people's drinking water, use Ozone disinfection is a fast and cost-effective method. Can drinking water be treated with ozone? What is the effect of ozone on tap water?
The oxygen source ozone machine has its own oxygen generator, which has high concentration, fast sterilization efficiency and good effect. It is the best choice for pure water, bottled water and other production water or drinking water.
Ozone has strong oxidizing properties and has four functions: oxidation, sterilization, decolorization, and deodorization. The application of ozone is mainly for sterilization and disinfection. This is mainly because ozone has a strong oxidizing ability, and ozone can produce biochemical reactions with microorganisms such as bacteria, viruses, and pathogens at a certain concentration. Ozone has high energy, and it will quickly decompose into oxygen (o2) and single oxygen atom (o) at normal temperature and pressure. of oxidation.
When the solubility of ozone in pure water is 0.4-0.5mg/l, it can meet the requirements of sterilization and quality assurance, and the reasonable dosage of ozone is 1.5-2.0g/m3. The solubility of ozone in water increases with decreasing temperature and increasing pressure. Under actual production conditions, the ozone gas concentration is guaranteed to be 10mg/l, the contact time between ozone and water is 5-10 minutes, and the requirements can be met under the condition of good gas-liquid mixing and contact.
[**]t present, there are three main methods of adding ozone in purified water/bottled water/barrel water treatment:
One: Traditional aeration method --- aeration head, aeration disc
Operation mode --- the aeration method is to pass the ozone gas generated by the ozone generator into the bottom of the ozone reaction tank through the pipeline, and emit micro-bubbles through the aeration head and the aeration plate, and the bubbles will release the ozone in the process of rising Dissolve in water. The efficiency of mixing ozone by aeration method is generally 20-30%:
Two: Venturi jet mixing method
Operation mode---jet flow method is to form negative pressure in the air cavity in the jet device under the action of high-speed water flow, suck in ozone gas, and then crush the ozone gas by high-speed water flow to form micro-bubbles and fully contact and mix with water. The efficiency of mixing ozone by jet method is generally 25-40%.
Three: gas-liquid mixing pump
Mixing pump: It is generally a vortex type, forming a negative pressure in the pump, sucking gas (or liquid) into the suction port, and mixing gas-liquid and liquid-liquid through the stirring of multiple impellers. The efficiency of using a mixing pump to dissolve ozone is relatively high, generally 40-70%.
Four: Ozone mixing tower
Ozone enters the bottom of the mixing tower through the pipe, passes through the aerator, and emits microbubbles through the microporous bubbler. The bubbles fully dissolve the ozone in the water during the rising process. The water is scattered from the top of the ozone tower and flows away naturally from the top of the ozone tower. Ensuring sufficient time for ozone to mix with water. The sterilizing effect is better, and the top is equipped with exhaust gas discharge and overflow port to ensure that excess ozone will not stay in the room. affect staff productivity. The overflow port ensures that after the water inside the mixing tower is full, the water will not flow back to the ozone generator and damage the ozone generator.
The purpose of connecting the ozone to the ozone mixing tower is to fully dissolve the ozone in the water, and also to ensure sufficient time for the mixing of the ozone and the water, so that the bactericidal effect is more accurate.
The requirement for residual ozone concentration of 0.4mg/L comes from: GB19304-2003 "Sanitary Packaged Drinking Water Enterprise Production Hygienic Standard Specification" 8.2.1 stipulates that the residual ozone concentration is 0.4mg/L.
Ozone purification of tap water, the solubility value of the international conventional standard is 0.4mg/L, keep for 4 minutes.
Mineral water 0.2mg/L, purified water 0.4mg/L.
Under the premise of ensuring the bactericidal effect, it is better to have a lower ozone concentration
[**]ccording to related data, under the action of 0.45 mg/L ozone, the polio virus will die after 2 minutes. If chlorine is used for disinfection, it will take 3 hours for the dose to be 2 mg/L. When 1 mL of water contains 274~325 coliform bacteria , when the ozone dose is 1mg/L, the number of intestinal bacteria can be reduced by 86%: when the dose is 2mg/L, the water can be almost completely disinfected
1. Oxidize bacterial impurities in water and disinfect raw water
2. Ozone has strong decolorization, deodorization and deodorization capabilities, degrades organic matter in water, and can effectively improve the sensory indicators of water
3. Dissolving algae cells, killing and inhibiting the growth of algae
4. Ozone can quickly oxidize and precipitate iron polymers (corroding iron compounds) in the state of organic matter, and the combination of sand filtration can effectively remove iron
5. It will not produce disinfection by-products such as chloroform and other chlorine.
Through the principle of ozone, it can effectively disinfect and sterilize drinking water, purified water, mineral water, mountain spring water, and distilled water. In order to achieve better results, it is recommended that you use an oxygen source ozone machine. The above content is related to the application of ozone machine in the field of drinking water. I hope it will be helpful to everyone.
