Join the CIWEM East Midlands branch and ICE for their joint talk on Severn Trent Water’s biological phosphorous removal technology innovation and development over the last 25 years.
Severn Trent serves a population of approximately 8 million people, with over 1000 sewage treatment works. For over 25 years, the need for phosphorus removal in wastewater has been growing through the implementation of the Urban Wastewater Treatment Directive (UWWTD), and more recently the Water Framework Directive (WFD). This talk will go into more detail about the application of the WFD in bringing rivers up to good ecological status.
Prior to AMP6, Severn Trent had 123 sites with total phosphorus limits. Over 250 additional sites in AMP 6 and AMP 7 will require additional phosphorus removal at a wider range of site sizes and at tighter effluent limits than have previously been implemented; these challenges demand a variety of solutions.
Most sites use chemical phosphorus removal, using iron or aluminium salts to precipitate phosphorus. Severn Trent currently has over 20 sites running Enhanced Biological Phosphorus Removal (EBPR) plants. The application of EBPR is becoming more critical with the potential for chemical supply limitations and the associated environmental impacts. The application of biological phosphorus removal is becoming more and more critical with the potential for chemical supply limitations and the associated negative environmental impacts.
Carl Kissack
Carl Kissack MCIWEM C.WEM has worked for Severn Trent since 2006 in various engineering roles and now as a Senior Process Engineer is working on expanding the role EBPR will play in AMP7. Carl will explain the background of phosphorus removal requirements and the future strategic challenges. Carl is currently working on the process design for the solutions for AMP 7 and AMP 8 on wastewater sites.
Rowan Luck
Rowan Luck MCIWEM C.WEM is Treatment Process Team Lead and has
worked for Severn Trent since 1998 in various roles as a Process Scientist in
wastewater. Rowan will give us a review of the development of EBPR from pilot
trials to full scale implementations. Rowan is currently working on optimising
the AMP6 WFD schemes, along with delivering the AMP 7 capital schemes.
