Ozone Nanobubble Oxidation & AOP Cases

Cases cover organic color, textile and livestock wastewater, and Fe/Mn oxidation, with results varying by water quality, temperature, ozone dose, and reaction conditions.

CASE 01

Oil-Based Ink Oxidation & Decolorization

Ink color decreased over time, confirming basic oxidation behavior and potential for organic-color treatment.

Oil-based ink oxidation and decolorization with ozone nanobubbles
Ozone Nanobubble Oxidation & Decolorization Confirmed
Measured: 2022.03.22 (water 9.0°C)
Test Target
Oil-based stamp ink
Evaluation
Oxidation and decolorization of ink
Observation Decolorization observed with oxidation
Implication Potential for organic color treatment

※ Basic test only; results vary with contaminant, ozone level, temperature, and reaction time.

CASE 02

Ozone Treatment under High-Temperature Textile Wastewater Conditions

Above 80°C, ozone retention and oxidation were less favorable, and some blue color remained; temperature and reaction conditions require control.
