Intensifying Nitrification at Severn Trent’s Spernal Plant with OxyMem™ MABR Modules
Severn Trent’s Spernal Wastewater Treatment plant deployed OxyMem™ MABR modules to help the facility Grow With The Flow
At Severn Trent Water’s Spernal wastewater treatment plant in the UK, managing ammonia loads becomes especially challenging during cold winter months—when lower temperatures and additional reject water from sludge processing push conventional treatment to its limits. The utility needed a way to increase nitrification capacity and protect effluent quality, without expanding infrastructure or disrupting live operations.
By installing OxyMem™ MABR modules directly into an existing activated sludge lane, Severn Trent Water was able to intensify treatment within its current footprint. The modular system was installed while the plant remained fully operational and quickly delivered measurable improvements in ammonia removal and process stability, particularly during high‑load and cold‑weather conditions.
