Ozone mist Sterilization

Ozone-mist sterilization for non-chemical agriculture

Recent mass production in large-scale agricultural farming supported by monoculture, agricultural chemicals, high mechanization etc. resulted in loss of biological diversity, fungus resistance, degradation and erosion of soil, pesticide residues and pollution (air, soil and water). In order to solve these global environmental issues occurring in human life, ozone has attracted much interest in alternative technology for sterilization and purification in agricultural management. Ozone is one of alternatives to agricultural chemicals and helps promote a more sustainable agricultural system.

We have developed an ozone-mist sterilization which is carried on the back of farmers . This backpack type system is designed for agricultural farms located in remote rural areas where ethnic groups have engaged in chemical-free agriculture under poor infrastructure of electrical power supply. 

Technological requirements for this non- chemical sterilization system are followings;

(1)kill living small insects, worms, bacteria and viruses at high sterilization rate(90%) in short operation time(10-20sec) ;
(2) Oxygen gas and water as original materials produce an ozone-mist creating pesticide radicals which kill microorganism;
(3) secure  farmer health from ozone exposure ;(4) leave no harmful residues on the produce.

Ozone-mist sterilization system for agriculture

Our system of the ozone-mist sterilization is composed of an ozone generator, a water-mist supply system, an AC-DC inverter connected to Li-ion battery, a lightweight oxygen vessel (FRP) with a pressure regulator, a water tank and a movable spray rod with ozone-mist nozzle .
High dense ozone which is suitable to sterilize insects, worms, bacteria and viruses is generated by surface dielectric barrier discharge (SDBD).
The HV electrode of the SDBD is embedded inside the dielectric plate and molded. The dielectric barrier discharge was generated on the surface electrode
