OxyMem MABR-Severn Trent - Case Study

Project Details

Challenges
The consumption of energy is one of the highest operational costs for Severn Trent and the main
cause of greenhouse gas emissions for the company.

Solution
MABR system can potentially reduce up to 75% energy consumption compared to conventional activated sludge using bubble-based aeration.

Energy reduction
They were seeking a solution that reduced their energy consumption while also benefiting their
customers, their business and the wider environment.

OxyMem MABR
Combined biological treatment for carbon and nitrogen removal which brings effluent to required discharge standards, all incorporated into a single compact structure.

R&D
In 2013 Severn Trent and OxyMem began a collaboration to test the benefits of Membrane Aerated Biofilm Reactor (MABR) in an attempt to meet more stringent water quality requirements while also reducing energy consumption.

Robust treatment
Removal of COD, ammonia and nitrogen even as a high loaded pre-treatment step. Simultaneous nitrification and denitrification.
