Water utilities around the world are having deal with increasing contamination of source waters while complying with tighter environmental regulations.
In the United states, a substance either has to be declared as GRAS by a recognized panel of food experts, or approved as a "food additive" by the USFDA for it to receive widespread acceptance.
Process water treatment in pharmaceutical companies, food and beverage industries, chemicals, and allied industries assumes a very important role in maintaining standards that are very stringent.

FAQs
Ozone technology uses corona discharge, electrolysis, or UV principles to generate ozone for the purposes of disinfection and oxidation.
Ozone is an electrophile with a high redox potential; hence, it finds use in any application that requires oxidation in water and wastewater treatment like colour and odour removal, COD reduction, pollutant removal, disinfection, etc.
Being an allotrope of oxygen, ozone forms no harmful by-products after reaction and is the most environmentally friendly oxidant available commercially.
Ozone can be generated using three different methods. The UV method of Ozone generation uses UV light shorter than 240 nm wavelength to generate Ozone. This method is generally used in very low-concentration applications like air treatment only. In applications that require a higher concentration of Ozone, corona discharge or electrolysis is the preferred method of Ozone generation.
The Corona discharge method uses a high voltage barrier discharge method to generate Ozone at high concentration. Ozonators /Ozone generators using this method are used in water and waste water treatment applications like colour and odour removal, COD reduction, pollutant removal, disinfection, etc.
Electrolytic Ozone generation method uses a PEM [Membrane] to generate Ozone directly from pure water. This method generates small amounts of Ozone at very high concentration and is used only in pure water, ultra pure water and water for injection applications for disinfection and loop sanitization.
The cost of an Ozonation package depend on a lot of factors
Feed gas quality: Ozone efficiency and Ozone generator reliability depends on feed gas quality. Higher the quality of the feed gas, higher the Ozonator reliability and efficiency and higher the CAPEX . However, operational and maintenance costs will be substantially lowered.
Ozone concentration : Generating Ozone at higher concentration will usually drive the cost of an Ozone project higher, while lowering the operating costs
Safety features : Ozone package prices are directly proportional to the safety features embedded in the Ozone generator. However, in-built safety can increase the reliability of an Ozone generator and reduce lifetime ownership costs substantially.
Mixing technology: The type of mixing technology used can affect the price of the Ozone generator. Efficient mixing can increase the efficiency of the Ozonation process and is one of the most overlooked aspects of Ozone design and engineering by Ozone manufacturers.
Ozonators /Ozone generators need treated air or oxygen [low dew point] to generate Ozone.
Apart from feed gas, commercial Ozone generators require cooling water to cool the Ozone electrodes and increase Ozone production efficiency
Ozonators using corona discharge method produce high frequency/high voltage power to generate Ozone and hence require supply power of around 7-10 KW/Kg of Ozone generated.
