TG-40 Ozone Generator
Analysts interested in studying the disinfection of wastewater with ozone and/or researching ozone disinfection byproducts like hydroxyl radicals should consider producing ozone with the ozone generator. The ozone generator creates ozone saturated water. The ozone generator (TG-40) creates an intense spark of electricity inside a chamber called a corona cell by forcing a high voltage source through a dielectric insulator and air gap. When oxygen flows through the air gap, sparking occurs splitting oxygen molecules (O2 → O- + O-). Single oxygen atoms react quickly with other oxygen molecules to create ozone (O- + O2 → O3). Ozone is then pumped into a reaction chamber containing cooled 2˚C ultrapure water. Once the water becomes saturated with ozone, it may be used for experimental research. Ozone concentrations are determined by using a direct ozone quantification method with a spectrophotometer or a colorimetric indigo method with a spectrophotometer. Ozone concentrations created with the method typically range between 15 - 60mgL-1.
