  • We use combination of UV rays & Ozone gas to disinfect pool water instead of Chlorine which is much more safer for Skin and Health of swimmer because there is no residual chemicals to be harmful for Human, no carcinogen.
  • There is 2 types of UV rays in our system : 185 nm UV rays and 254 nm UV rays.
  • 185 nm UV rays will remove Total organics content ( reduce TOC ) and also reduce Algae production.
  • 254 nm UY rays will kill bacteria , Viruses , Molds without any chemical added.
  • Ozone gas will be mixed with pool water by Venturi to oxidize all pollutants in water and kill bacteria, Viruses, Molds, Reduce Algae.
  • UV rays will have no residual effect in the pool after passing UV reactor but dissolved ozone will remain exist in the pool 15-40 minutes depend on temperature of pool water (cold water will keep longer dissolved ozone) .Therefore in season which temperature is cold (lower than 20 celcius) without sunlight -> No use of Algaecide solution.
  • But in Hot season & direct sunlight exposure , Algae may build up (since dissolved ozone can exist in water only 15-40 minutes). Therefore strongly recommend to mix Copper Sulphate solution at concentration 0.5 gram/1,000 liters of pool water per week to completely prevent Algae production.


Total Chlorine – Free Chlorine = Combined Chlorine
Combined chlorine does not kill bacteria and viruses, cause various health related problems ,strong odor .Chloramines (combined chlorine) are poor sanitizers and have a gaseous tendency
Continuous researches already proved that Chlorine create various Health related problems i.e Chloramines (there is 3 types : mono-, di- and tri- chloramines) ; nitrogen trichloride.
Introduction Ultraviolet systems to combine with Chlorine in swimming pool because of  the ability of UV rays to break down and remove combined chlorine, chloramines.


All UV-C system which produce 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 removes all types of Chloramines (mono-, di- and tri- chloramines).

After just a few days of UV operation, combined with chlorine level typically fall to 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 clear looking.

Our OUV system also provide an increased level of disinfection, protecting against most of chlorine resistant micro-organisms 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 has been used for algae elimination for years with very good results. When compare ozone with some other very strong oxidants; ozone obtains very good results in a short amounts of time more than Potassium permanganate & Chlorine & Hydrogen Peroxide. Combined system UV sterilizer and ozone perfectly control the algae formation. For almost all kind of algae, ozone can reduce  more than 95%. Ozone systems effectively fight against Algae and maintain superb water quality. Marine hobbyist recognized the advantages of Ozone systems along the past .Without dispute, Ozone is the most effective natural bactericide and viricide of all disinfecting agents available.
In  pond environment Ozone:
  • Highly effective in removing organics, and reducing ammonia and nitrites.
  • Act as a sterilizing agent to kill viruses, bacteria and other pathogens.
  • It is economical and non-polluting when used correctly.
  • Improves biological and mechanical filtration by burning off proteins, ammonia and nitrite straight to nitrates and by enriching our pond water with Oxygen. Lowers biological oxygen demand (BOD) and raises the REDOX potential in the water (the ability of the water to oxidize pathogens).
  • Can remove toxic pollutants, such as hydrocarbons and other toxic substances from  pond water which cannot be achieved by any other form of mechanical or biological filtration.

When Ozone contact with the water it quickly ‘burns’ off polluting organic material and breaks down back into Oxygen. As well as disinfecting the water and killing bacteria, viruses and free swimming parasites, Ozone also kills algal cells. The disinfected water returned to the pond is also saturated with oxygen so that the biological filter is able to work at its full potential. Ozone is so powerful that it is similar to having a dose of Chloramine T or Potassium Permanganate in the pond, without any of the chemical side effects. As Ozone also burns off proteins and organics water clarity is improved enormously and the water sparkles to the point where the color of the pond is not impeded in any way by the depth of water. To correctly calculate the size of Ozone generator to achieve optimum Ozone dosage. When using oxygen as a feed gas, via an oxygen generator for Corona discharge ozone generator; it requires minimum 0.3 gm of Ozone per water 1,000 gallons or 0.08 gm per 3.75 cubic meter.
