Dew India

Ozone is “active oxygen”, nature’s special element and a beautiful gift to mankind. Ozone is a triatomic allotrope of oxygen formed by recombination of oxygen atoms. It is a colourless gas with characteristic pungent odor and can easily be detected at low level of 0.05 ppm. It is a very strong oxidant and is over 3000 times more powerful disinfectant than chlorine. It disinfects, oxidizes, deodorizes and decolorizes.

Dew manufactures high graded Ozone Generators and Ozone Systems for virtually each of ozone applications such as Packaged Drinking Water, Swimming Pools, Waste Water, Industrial Application etc. Manufactured strictly in compliance with International Standards the innovative modular design in conjunction with our unique electrodes for each ozone generator model guarantees their highest efficiency, operation safety and reliability. Ozone is produced starting from air sucked from ambient, compressed and transformed in ozone. Dew ozone generators is fully assembled and tested in factory. It includes mechanical, electrical and instrumental fittings including compressor.


  • Ozone is 51% more powerful on bacterial cell walls than chlorine.
  • Ozone kills bacteria 3100 times faster than chlorine.
  • Ozone is the most powerful broad spectrum microbiological control agent available.
  • Ozone virtually eliminates all chemical usage. Ozone is chemical-free; it produces NO toxic by-products.
  • Ozone is clean and environment-friendly; its only by-product is oxygen.
  • Ozone is extremely effective as a disinfectant at relatively low concentrations.
  • It is generated on site, eliminating the transporting, storing and handling of hazardous materials.
  • It is very inexpensive to produce and has an unlimited supply.
  • Its much safer for employees than conventional chemicals. Its extends the shelf life of food products.
  • Its permits recycling of wastewater. Its reduces Biological Oxygen Demand (BOD).


Drinking Water

Ozonation is one of the method to convert impure water into to pure drinking water ,ozone inactivares and destroys all bacteria,virus and protozoa’s. Ozone will oxidise both organic and inorganic substances, remove unwanted taste, odour and color, and provide effective disinfection.

  • Most powerful oxidizer available
  • improves flocculation of iron
  • Increases the shelf life of bottled water.
  • Produces safe & bacteria-free drinking water.
  • Removes heavy metals & cyanides from water.
  • Been used for decades
  • Iron and manganese removal
  • No harmful by-products
  • Environmentally friendly

Industrial Effluent Treatment

Ozone as a standalone system or with UV/H2O2 can remove COD, BOD from water up to 90%. It also removes various dyes from the water effectively up to 99%. Additionally ozone can be used for cyanide removal from effluent. Pesticide industry also finds a wide application of ozone for breaking down the harmful chemicals in their effluent.

Sewage Water Treatment

To remove odour and bacterial contamination from the treated sewage, ozone is the most preferred choice. The water can be reused for flushing, gardening or car washing applications.

  • Reduces Chemical Oxygen Demand
  • Reduces Biological Oxygen Demand
  • Removes Colour and odour
  • Reduces Oil & Grease
  • Removes Detergents
  • Reduces Pesticide
  • Reduces usage of Harmful Chemicals
  • Ecofriendly


Cooling Water Treatment

The circulating water of cooling tower systems has always been an ideal place for growth of microorganisms. The warm temperature of the water and the addition of nutrients from the scrubbed air flowing through the tower provide a virtual heaven for all sorts of microbes and algae. In turn, these organisms multiply at very high rates. The result is degraded system efficiency due to blockage of flow, shortened equipment life due to corrosion, increased operating cost due to higher pumping power requirements, and the spread of disease or even death.

Ozone as a cooling tower biocide offers a means to this end. It is not only environmentally friendly, but ozone use offers a significant number of other benefits to the cooling tower system. Ozone is a practical oxidizing biocide because it is the fastest acting and the most efficient oxidizing agent against all microbiological organisms – when properly applied, ozone will kill all viruses, bacterium, cysts, and algal species.

Pharma Process

In pharmaceuticals unit water is used for product manufacturing , washing, cleaning of the raw materials and the processing equipment. The microbiological quality of the process water in a food processing or pharma is of prime importance. The process water should be free from any bacteria, yeast, molds or any viruses for production of quality product. In case the process water is infected ,micro-biological counts of the product will be higher than stipulated and as these micro-organisms grow at a very fast rate, it will adversely affect on the quality of the product ,with respect of preserving freshness and shelf life.

Ozone not only disinfect water in very short contact time but do it in environmentally friendly manner.
