  • Operating experience of Aberdeen CAMBI thermal hydrolysis plant 2002

    Introduction This paper reviews the establishment of a new 50 dry tonne per day biosolids processing facility at a green field site at Nigg Bay, Aberdeen Scotland. Prior to 2001 all sewage had been pumped by long sea outfall into the North Sea. Consequently there was only a minor biosolids operation in the area dealing only with small, rural works. Proposals were sought from a number of ...
