Ozone Oxidation – A Solution for Reducing Industrial Wastewater Color and Water Reuse

Industrial paper production consumes large amounts of water while generating wastewater that is often contaminated with dyes and organic substances. To minimize water consumption and ensure a cleaner environment, advanced wastewater treatment technologies are essential.

One of the most effective methods for treating colored and organic-laden wastewater is ozone oxidation. This technology efficiently removes color, breaks down complex organic compounds, and reduces pollutants in water. Ozone is a powerful oxidizer capable of eliminating over 90% of filterable contaminants under optimal conditions.

Studies have shown that an ozone dosage of approximately 80 g/m³ can achieve significant color reduction in wastewater. Additionally, this method enables wastewater recycling for reuse in production processes, reducing the need for fresh water by up to 50%, saving tens of thousands of cubic meters of water annually in industrial settings.

Ozone oxidation not only helps to minimize environmental impact but also optimizes production processes, lowering operational costs and contributing to a more sustainable industrial future.
