Disinfection of potable water was one of the main improvements to public health in the 20th century where the use of chemical disinfectants in municipal waterworks reduced the waterborne diseases by far. Among different chemicals only chlorine, ozone and chlorine dioxide are of economic relevance.
Chlorine Dioxide (ClO2) is a powerful yet selective oxidant and biocide, disinfectant and sanitiser where it is becoming increasingly utilised for water purification. GraphEAT™ is a process whereby nano-cavitated chlorine dioxide is effectively utilised in water disinfection. Nano-cavitation of Chlorine Dioxide increases the solubility level by 10 times in water compared to chlorine and does not require chlorine gas generators which can be hazardous if not maintained well.
