Effluent Treatment, Torpoint

pdp Green were commissioned by the MoD to carry out studies and design a new treatment process for sullage.  Sullage is contaminated bilge water and is pumped from Naval and Royal Fleet Auxiliary ships to storage tanks onshore for treatment.

The main constituent of sullage is seawater, but is normally heavily contaminated with fuel oils, detergents, antifreeze and other chemicals. Improved environmental legislation for the quality of discharges required a new treatment process to be installed.
