News : Blackdyke to Kennett Tunnel cleaning

PSD have completed work with Delta Civil Engineering Limited on the Blackdyke to Kennett Tunnel near Newmarket for the Environment Agency. The project involved the removal of silts & vegetation from a water transfer tunnel & associated shafts, repairs to concrete tunnel lining & installation of monitoring equipment along 19.8km of 2.54m diameter tunnel at depths of between 30m & 78m. PSD supplied on rental to Delta a high capacity S4DP centrifuge, flocculation system, sedimentation tank & operator. Operating on a 24-hour basis, wash water from the tunnel was pumped to the PSD plant for flocculant dosing and removal of flocculated solids. The resultant clear fluid was discharged to the nearby Kennett Brook, a water-course monitored by the Environment Agency, and the separated solids were removed from site for disposal. High capacity centrifuges from PSD have a wide range of applications including soil washing, treatment of slurry from tunnelling and diaphragm walling projects, canal, dock and reservoir cleaning and the treatment of site run-off water. PSD's S4DP centrifuges are the largest throughput, containerised centrifuges in Europe and can be used for the removal of fine solids or for the removal of flocculated solids from process fluid to reduce the volume and cost of off-site disposal.
