Core Technology
Expected Effects of Ultrasound-Enhanced Cold Plasma System
Utilizing reactive oxygen and nitrogen species (RONS) generated by underwater plasma discharge, the process achieves over 99% sterilization efficiency through recirculation
Production of nitrate ions [NO₃⁻], the final absorbable form of nitrogen essential for plant growth, from water and air
Application of ultraviolet (UV) light and ultrasound for cell wall disruption of waste biomass (e.g., spent coffee grounds), enabling extraction of nutrients for plant cultivation
Cold Plasma
The formation of nitrogen-oxygen reactive species with UV radiation and shockwave-induced microbial cell wall rupture/ DNA denaturation
Low-temperature Plasma Technology
Atomic components maintain temperature imbalance, operating below 120°C
→ Expansion of application areas (Thermal plasma: 10,000°C)
Reactive Species
Ultraviolet
Shockwave
Simultaneous Utilization of Plasma-Generated Reactive Species, UV, and Shockwaves
Electrode discharge-induced ionization of water and air molecules
→ Reactive species-Induced rapid oxidation & permeabilization
Ultraviolet Emission and Acoustic Shockwaves during Plasma Formation
→ Cell membrane disruption for sterilization and component extraction
Cavitation
The formation and collapse of high-pressure bubbles destroy cell walls and extract bioactive compounds
Combined use of ultrasonic cavitation and pressure-drop nozzle–induced bubble cavitation
Pressure drop from higher in-channel flow promotes plasma-activated ion influx
→ Higher underwater active ion levels → Enhanced sterilization Ultrasonic-assisted decomposition of plasma-activated bubbles under pressure drop
→ Fragmentation of grown bubbles prolongs underwater lifetime → Boosts sterilization and dissolved oxygen Enhancing underwater microbubble concentration using ultrasound and high-pressure nozzles
→ Maximized waste resource recovery via multi-bubble cavitation (cell wall rupture) CavitationConversion of Air into Fertilizer via UECP system
