The selected technology will maintain ammonia consent standards during an upgrade of a village treatment works.
WD News: Severn Trent Water is upgrading the wastewater recycling plant serving Albrighton in Shropshire, UK. Planned for the end of 2022, the project will be undertaken by the utility’s contracting partner, construction company Galliford Try.
WCSEE will provide two T1000 Hybrid-SAF™ – submerged aerated filter – treatment units, to deliver ammonia removal at the plant while existing treatment processes are offline during the construction phase.
The SAF units will be able to treat a peak flow of 25 l/s, while maintaining compliance with environmental permit requirements for ammonia of 4mg/l ammonia. The Environment Agency’s regulations state the site must meet these standards at least 95% of the time.
Andrew Haywood, Utilities Manager for WCSEE said, “During a treatment plant upgrade, it is critical that stringent ammonia removal continues to be delivered while parts of the site are taken offline. This is an absolute priority for utilities – environmental compliance must be maintained throughout construction, to protect local watercourses and avoid regulatory penalties.”
Andy Bradford, Service Delivery Manager for Severn Trent said, “The hybrid-SAF technology will be key to keeping our Albrington works fully operational and compliant while construction, led by Galliford Try, is underway.”
