Lessons from UK’s first ozone-based micropollutant removal plants
Britain’s first ozone-based micropollutant removal plants hold lessons for utilities preparing to tackle PFAS and micropollutants before regulation is introduced. Since Curio Water engineered and helped deliver the UK’s first ozone-based micropollutant plants at Severn Trent last year, we’ve learnt a lot about the practicalities of how utilities can deploy the latest innovations to deal with new and emerging contaminants. This includes PFAS, microplastics and micropollutants – all of which are currently facing growing public and regulatory scrutiny. For utilities and those seeking to work with them, the challenge is essentially threefold. First and foremost, any treatment infrastructure must be built around rigorous pilot testing to fully understand the water matrix and its behaviour in response to treatment. This is not simply a matter of understanding what contaminants are present, but whether they fluctuate seasonally, how the presence of certain contaminants can affect previously proven treatments and ultimately the long-term effectiveness of a co-ordinated train of removal technologies. The second is a dose of realism when it comes to working with existing infrastructure and understanding …
