University works on sewage

The three-year project will assess phosphorous removal technologies, which can be problematic for smaller sewage works due to stringent rules and high costs.

Project leader Dr John Williams, from the school of civil engineering and surveying, said: ‘The first challenge is to address phosphorous removal technologies, this will be followed by studies of optimisation of existing assets and then evaluation of emerging technologies.’

This collaboration is based around the University Environmental Technology Field Station at Petersfield Wastewater Treatment Works.

Portsmouth is the only university in the UK to have a research field station at a full-scale operational sewage works.
