Description

The first quaternary treatment schemes are currently being implemented in the UK in response to inland bathing water standards, with future micropollutant drivers expected in response to the new UWWTD standard that are being adopted in mainland Europe.  The Aurea technology for micropollutant is a two-step process comprising biological activated carbon filtration (BACF) followed by ozone treatment. The combination of these two technologies has demonstrated a significant reduction in ozone (50-75%), due to the removal of DOC, nitrite and part of the micropollutants by the BACF. This delivers low OPEX and whole life carbon.

This presentation will provide a brief overview of the technology, provide an update on the first full-scale plants in the Netherlands and provide business case examples for a range of WwTW’s for application in the UK.  Details of CAPEX, OPEX and operational carbon assessments in comparison to alternatives will be discussed along with discussion of other opportunities in terms of the impact of Aurea on nitrogen, phosphorus and disinfection as well as application as a PFAS-removal pre-treatment. Opportunities for integration into existing assets will also be discussed, including installation of BACF before existing ozone and conversion of tertiary sand filters into BACF reactors.
