Description

The entry of fat, oils and grease (FOG) into the wastewater system from both domestic and food-establishment sources has become a major problem for the management of wastewater in several major cities.  Indeed, the UK has seen several high-profile blockages caused by FOG deposits in sewers in recent years, phenomena that have now been termed ‘Fatbergs.’

In this project we are investigating the environment within sewers where FOG accumulates to better inform the design of reliable tailored FOG treatment.  This includes the microbiome, isolation and characterisation of lipid degrading bacteria, which have shown promising results in the degradation of FOGs in synthetic wastewater, and the lipid content of the Fatberg itself.
