  • Thermal hydrolysis, anaerobic digestion and dewatering of sewage sludge as a best first step in sludge strategy: full scale examples in large projects in the UK and strategic study including cost and carbon footprint.

    Abstract This paper shows that by using thermal hydrolysis process (THP) as a pre-treatment for anaerobic digestion (AD) it is possible to develop a step wise approach to sludge strategy that is cost effective and flexible. By generating a low volume of non odorous, well dewatered and safe digested cake it is possible to recycle sludge directly to agriculture or dry it for fuel use or ...

  • Gatineau Sewage Treatment Plant, Gatineau, Quebec, Canada

    Project No. 1 Industrial Boiler Application A FLU-ACE waste heat recovery system installed to process all flue gases from three boilers. The system recovers up to 3.5 mmBTU/h of waste heat which is re-used for heating the digester sludge. The main fuel for the boilers is recycled methane based sewage gas generated from the plant’s anaerobic digesters. 'The installation ...

  • 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 ...

  • Where does mold come from?

    Molds are among the earliest known life-forms; they are found in all parts of the world, including Antarctica (“Scientists Tackle Antarctica Mold,” Peter Rejcek, editor, Antarctica Sun, February 4, 2007). They do not have mouths or digestive tracts. Instead, they release digestive enzymes that break down paper, fruits, leaves, shoe leather, bacon or anything else they have landed on ...

    Abstract SHARON8 is a very cost-effective treatment system for the total removal of nitrogen components, through nitriflcation/denithfication. from wastewater flow streams containing high concentrations of nitrogen. The system is used for the treatment of municipal wastewater side streams from both dewatered digested primary sludge and waste activated biosolids to achieve high total ...
