The Ozonation Series – episode 2: How the water matrix impacts your ozonation process

In the first blog of The Ozonation Series, we discussed why modelling is an exciting solution for the ozonation of secondary effluent or surface water and the benefits of the AMOZONE model. This article zooms in on the water matrix and why it makes designing and running an ozonation plant a challenge.

The importance of the water matrix

Each wastewater treatment plant has a specific type of water. Therefore, the water matrix is always different as target contaminants, organics, inorganics, pH, ammonia, carbonates etc., vary widely.

These have a significant impact on ozone consumption, hydroxyl radical formation and scavenging, and bromate formation. That’s why your specific water matrix affects your overall (future) design, the feasibility of your ozonation system and your operations.

What drives these matrix changes? Several factors do, including:

• Sewer network design and size
• Local climate and weather
• Local soil composition
• Upstream biological treatment plant operation, including aeration control, type of process, sludge age (SRT) etc.
• Wastewater sources (industrial vs. municipal)
• Drinking water matrix composition
• And many more

Removing the uncertainties concerning the water matrix

It’s essential to interpret your matrix right and draw the correct conclusions. Even with the same ozone dosages, there can be a big difference in ozone and radical exposure. This has an impact on the design and performance of your ozonation system and the micropollutant removal at your specific plant.

What’s more, a water matrix is dynamic and changes over time, making the ozonation process even more challenging.
