For application of bottled water, the dosage is 1~3g/t, and it can only be used after standing for more than 8 hours.

The use phenomenon of conventional manufacturers: the ozone concentration in water is 0.2mg/L~0.4mg/L, and some small manufacturers are less than 0.2 mg/L; If the standing time needs to shorten the corresponding ozone concentration low point.

Ozone sterilization technology for bottled drinking water;

In bottled drinking water, different ozone dosing processes have different mixing effects, which have great influence on sterilization effect, and the dosing method is also very important.

There are four main ways to mix ozone and water:

The first method of ozone mixing-aeration: ozone is introduced into water by aeration head and aeration disc to generate microbubbles, and ozone is dissolved in water when the bubbles rise. The mixing efficiency of ozone by aeration method is generally 10-20%, which is low and the concentration in water is difficult to reach 0.4 mg/L.

The second method of ozone mixing-jet type: ozone is dissolved in water by using the negative pressure adsorption principle of Venturi jet device, and the conversion rate can reach more than 25%, which is the most widely used mixing method at present.

The third method of ozone mixing-negative absorption: the efficiency of mixing tower is higher than that of jet, and the fusion effect is good, but the one-time cost is relatively high, so the outlet pressure of ozone generator should be considered.

The fourth method of ozone mixing-gas-liquid mixing pump type: ozone gas-liquid mixing is carried out by using Nanfang pump or Niconi pump, and the ozone mixing efficiency of the mixing pump is generally 40-70%. However, the gas-liquid ratio is strict, and the mixing effect is the best when the gas-liquid ratio is 9: 1.
