Ozonation in water treatment

Ozone is an unstable gas, composed of three oxygen atoms, which can easily be degraded back to oxygen. In this process, a free oxygen atom, or free radical form, is used. Oxygen radicals have strong reactivity and short life, and can only survive for a few milliseconds under normal conditions.

Ozone is a colorless gas, and its odor is similar to that of the air after thunderstorm.

Compared with chlorination, ozone has stronger disinfection effect on bacteria and viruses. In addition, the oxidation performance can also reduce the concentration of iron, manganese and sulfur, and reduce or eliminate the taste and odor problems. Ozone oxidizes iron, manganese and sulfur in water to form insoluble metal oxides or elemental sulfur. These water insoluble particles are removed by post filtration. Organic particles and chemicals are eliminated by coagulation or chemical oxidation. Ozone is unstable and it will degrade in a few seconds to 30 minutes. Degradation rate is a function of chemical properties, pH value and water temperature.

Main advantages of ozone

1. ozone plays a role in a wide range of pH, can react with bacteria, viruses and protozoa rapidly, and has stronger bactericidal performance than chlorination. The oxidation ability is strong and the reaction time is short.

2. no chemical substances are added to the water during the treatment.

3. ozone can eliminate various inorganic, organic and microbial problems, as well as taste and odor problems. Microbial preparations include bacteria, viruses and protozoa (such as flagellates and Cryptosporidium). Screening test of pathogens and water borne diseases.

Based on Bluamec, we develop and manufacture devices that produce aqueous ozone – the simplest, safest, most sustainable way to clean and sanitize. Our mission is “reducing chemical pollution, improving quality of life”.
