Detailed Product Description
1. Theory evidence:
Scientists have discovered that added UV in ozone disinfection system can stimulate activity of ozone, and catalyze ozone & water molecules to create plenty of hydroxyl radical (OH). OH is active material which was produced by reaction of ozone with water.
The oxidizing ability of OH is 100 times higher than hypochlorite (OCI).
The sterilization ability of OH is 3000 times higher than hypochlorite (OCI).
The sterilization ability with UV & Ozone is 1-2 times higher than use ozone individual.
2. UV-O3 Disinfection system used for pool water
UV-O3 system has the strongest ability of sterilization and inactivated virus, which can effectively prevent the spread of infectious diseases. Experiment proof that inactivation of fecal Escherichia coli requires only 5 seconds, if want to achieve the same affection with the same concentration of chlorine required 15,000 seconds. Some of the pathogenic bacteria are resistant to chlorine, such as virus, Amoebae, Cysts etc. But all of them can be killed by OH.
UV-O3 system has strong oxidizing ability. It can prevent the special odor compounds accumulated in swimming poor water, including Chlorinated organics what is reacted by chlorine with excretion, for example, monochloro amine, dichloramine, trichloramine, THM, chloriduria etc. Most of them are precursors of THM. But ozone can constantly prevent generation of precursors in swimming pool, to supply clear water, fresh air for swimmer, and without stimulation to their eyelids and nose strip.
UV-O3 system also can help sand filtration to removal of metallic salts and organics. Because the organics will easily become multi-polar compounds during oxidation process, and can combine with a number of multivalent metallic cations (eg. Ca, Mg, Fe, Al etc) into the complex compounds. And become micro-flocculate were removed by sand filtration last.
3. System Structure
Use booster pump, injector and reaction tower for ozone mixing in water, then water return to pool. Because the irradiation of UV has greatly increased generate of OH. OH speeds up the oxidation and sterilization efficiency for water.
UV-O3 system, because it using UV, it not only have an excellent effects of sterilization & oxidation under low ozone output working condition, but also can avoid risk of high ozone concentration in swimming pool (eg. >0.15 Mg/L). With using UV for small size of reaction tower, there is no need to use activated carbon for ozone destructor which can save much cost.
UV-O3 can reduce the dosage of chlorine. If the efficiency can match with requirements of sterilization and oxidation, the amount of chlorine could be further decreased, combined chlorine, free chlorine can be respective lower than 0.2 mg/L, 0.4 mg/L in water. The chloramines and THM have been substantially reduced to a certain extent. It will be the important part for meet with the requirements of environmental protection.
In UV-O3 system, OH has strong oxygenolysis ability for organic pollutants. The production of OH and its reaction with organic pollutant only can be carried out under UV. Using UV-O3 system can save 40% cost than use ozone only.
4. Benefits Summary Of UV-O3 System
