HOW OUV SYSTEM (Ozone Generator with UV Sterilizer) BE BETTER?
All UV-C system which produces a peak output of 254nm UV rays break down and remove health-related problem with chloramines which are formed when free chlorine reacts with organics such as sweat, body fats, and urine. But our OUV system, unlike general UV-c system; our OUV are polychromatic and have a broader UVC peak output at 185nm and 254 nm. This broader range of UVC light output can remove all types of Chloramines (mono-, di- and tri-chloramines).
After just a few days of UV operation, combined with chlorine level typically fall too low as 0.1 ppm or lesser. It will reduce all health-related Problems with itchy skin, burning red eyes, chlorine smell and corrosive properties are eliminated. Pool water is transformed to sparkling and clean looking.
Our OUV system also provides an increased level of disinfection, protecting against most of the chlorine resistant microorganisms such as Cryptosporidium and Giardia, which have a thick outer membrane making them highly resistant to traditional chemical disinfection. By adding ozone to the water to oxidize ammonia and nitrogen compounds. The longer the system operates, the more the ozone can destroy the ammonia and nitrogen.
Ozone producing UV lamps emits UV light at both rays 185 nm and 254 nm. When ambient Air is passed over an ultraviolet lamp, UV 185 nm will split oxygen (O2) molecules. The resulting oxygen atoms (O-), seeking stability, attach to other oxygen molecules (O2), forming ozone (O3). The ozone is injected into the water, or air stream, where it inactivates contaminants by actually rupturing the organisms’ cell wall.
There are 3 main applications of Ozone-UV sterilizer in the Water Treatment Industry.
Ozone producing lamp emit UV rays at both wavelength 185 nm and 254 nm
1) Disinfection flowing water by UV 254 nm and Ozone gas.
Our Ozone producing UV lamp generate both 254 nm and 185 nm wavelength. Water flow being sterilized by UV rays 254 nm inside S.S reactor chamber while venturi mixer draws air flow pass thru UV lamp. UV rays 185 nm react with airflow over UV lamp inside quartz sleeve to produce ozone gas and mix with water at outlet pipe.
OZONE EFFECTS ON SPECIFIC BACTERIA, VIRUSES, AND MOLDS
Ozone interferes with the metabolism of bacterium-cells, most likely through inhibiting and blocking the operation of the enzymatic control system. A sufficient amount of ozone breaks through the cell membrane, and this leads to the destruction of the bacteria. Viruses are small, independent particles, built of crystals and macromolecules, Unlike bacteria, they multiply only within the host cell. They transform protein of the host cell into proteins of their own. Ozone destroys viruses by diffusing through the protein coat into the nucleic acid core, resulting in damage of the viral RNA. At higher concentrations, ozone destroys the capsid, or exterior protein shell by oxidation so DNA (Deoxyribonucleic acid), or RNA (Ribonucleic Acid) structures of the microorganism are affected.
2) CHLORINE / CHLORAMINES DESTRUCTION:
UV rays effectively eliminate residual chlorine/chloramine remain in the water. Increasing recognition of the undesirable, negative effects of conventional dechlorination technologies such as activated carbon filtration and sodium metabisulfite injection. Carbon filter media are excellent breeding grounds for bacteria to proliferate. Chemical added give various undesirable drawbacks. Ozone-UV is a chemical-free alternative to the use of chemicals and activated carbon beds, effectively destroy chlorine/chloramine, eliminate complicate chemical handling, bacteria problems, etc.
3) TOC REDUCTION:
UV rays 185nm promotes the formation of free radicals, leading to the oxidation of organics into CO2 and H2O and is more powerful than the 254nm used in disinfection applications.
It is really safe and effective alternative for TOC destruction, providing low maintenance costs and utilizing non-toxic UV light with minimal by-products.
Although UV 185 nm can destruct TOC it requires higher energy than germicidal dosage, therefore you have to reduce optimum flow rate by 80%-90% of germicidal flow rate to achieve the purpose of destruction of Chlorine/Chloramines/TOC.
The type of fused quartz used to make the bulb, or envelope, of a germicidal lamp determines the wavelengths of ultraviolet (UV) emissions that react with the oxygen in the air to produce ozone. Ozone is an extremely active oxidizer. It destroys microorganisms on contact and also acts as a deodorizer. One of the primary advantages of ozone is that it can be carried by air into places that UV radiation cannot directly reach.
Very High (VH) germicidal lamps which generate energy at 185 nanometers (nm) in addition to the Low (L) 254 nm line. VH lamps are made with clear fused quartz and L lamps are made with a specially doped fused quartz that prohibits the emission of energy at 185 nm. VH lamps are used in a variety of settings including the treatment of air, pool, and spa water. The process of Total Organic Compound (T.O.C.) reduction also utilizes VH lamps. These lamps are also commonly used in the heating ventilation and air conditioning (HVAC) industry.
