Containerised CellCap installation recovers marketable cellulose from sewage

Earlier this month we had an excellent visit to Severn Trent Water’s Net Zero Hub Sewage Treatment Works in Strongford. A containerised CellCap installation is set up on site to recover cellulose from sewage water.

Severn Trent is aiming for the world’s first carbon neutral wastewater treatment plant in Staffordshire and cellulose recovery plays an important role in this. Applying the containerised plant, having a capacity of 450 m3/h (125 l/s), makes cellulose available to potential off-takers before the full-scale is fully operational.

The setup of the temporary CellCap plant with the downstream dryer and an impression of the full-scale plant under construction are shown below.
