Circular solutions for :

Spernal WWTP is a medium sized plant that serves as Severn Trent Water’s “Urban Strategy Demonstration Site” where merging technologies compatible with a low energy, circular economy approach will be evaluated.

A multi-stream technology test bed will be constructed in 2019. The demonstration plant will incorporate an anaerobic membrane bioreactor (AnMBR) complete with a membrane degassing unit to recover dissolved methane. AnMBR combines several benefits such as: no aeration energy for removal of Chemical and Biochemical Oxigen Demand (COD/BOD), low sludge production and associated treatment efforts, biogas production (production of electricity/heat), pathogen and solids free effluent which can be re-used in a number of applications (e.g.: farming and industrial use).
