Description

The 2024 EU Urban Wastewater Treatment Directive (EU 2024/3019) will require micropollutant removal from municipal wastewaters. It follows a water protection law that came into effect in Switzerland in 2016 which obliges selected wastewater treatment plants to reduce the discharge of micropollutants into receiving waters. 

Around 100 wastewater treatment plants in Europe already use a process for the removal of micropollutants, and the first plants are now being installed in the UK. Typical treatment alternatives are either adsorptive (GAC or PAC) or oxidative (ozone), and sometimes a combination of both processes. 

This paper summarizes the results of nearly ten years of operating ozone systems for micropollutant removal and discusses the effects of combining ozone with other treatment steps.

Details of selected plants - Neugut (ozone and sand-filtration), Warburg (ozone and mixed-bed bioreactor), and Altenrhein (ozone and activated carbon) - will be presented.

Specifically for the UK, a fleet of pilot plants are being built by Curio with combination possibilities of different treatment steps including ozone.

Using the experience gained from the European references in combination with the site-specific results of the pilot plants will ensure that future projects in the UK benefit in terms of design, operation and service.
