This technology injects wastewater in a viscous slurry state, shock waves are generated when the molecules of all substances contained in the wastewater are sheared, and the wastewater slurry is discharged in an oxidation-reduction state. and liquid molecular property change reaction process. In other words, the odor and viscosity are removed from the fine suspended matter, and the nanoemulsion (ultra-homogeneous) wastewater discharge is separated into liquid and solid phases, so no separate chemical treatment or filtration process is required.
