Mersey Valley Processing Centre
Mersey Valley Processing Centre
An advanced system for the treatment of ammonia in wastewater
A major extension at the Mersey Valley processing centre resulted in strong centrate liquors from the new dewatering process. By incorporating the SHARON process, United Utilities is making an active effort to protect the environment by treating these liquors before discharging them to Widnes waste water treatment works.
Future adoption and expansion
The Mersey Valley processing centre near Liverpool will treat 1,650kg NH3-N per day. It is expected that the use of the technology will spread throughout the UK, as other utilities recognise that by treating the sludge liquors separately with an efficient process, the loads on the main treatment works are considerably reduced.
Incorporating a SHARON plant reduces energy usage by 25% and carbon dioxide emissions by 20%, while converting to nitrite uses 40% less carbon source in the process than conversion to nitrate.
