  • An operating tale from næstved sewage treatment plant

    Conversion from a two-stage to a one -stage plant Næstved Central Sewage Treatment Plant was built as a Bio DeNiPho plant to treat 89,000 PE and the load is about 45,000 PE. The results of analyses of the micro pollutants indicated already in 1998 that we would face problems with export to the agriculture segment after 1 July 2000. At the same time the industry started saying that the micro ...

  • 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 ...

  • Municipal waste water treatment plant case study

    A municipal WWTP in the North of England was experiencing significant problems with accumulations of FOG in the Wetwell at the head of the treatment plant. The FOG would form a solid cap over the well several feet thick. This put considerable strain on the pumping gear, interrupted the performance of the float switches and required regular manual intervention from the staff. High costs were also ...

  • Municipal sewage application (Nagano Prefecture) case study

    Squeeze sludge fresh out of the reactor. Don't wait until it stinks! In the wastewater treatment plant of a town in Nagano, the long-used belt press was in a time to be overhauled. The person in charge had racked his brain over the problem of huge cost required to overhaul this equipment at regular intervals. He had been seeking a solution to this problem. In addition, he had to cope ...

  • Co-composting of sewage sludge and municipal solid waste

    Israel production of sewage sludge and MSW grows each year due to the increasing number of modern Wastewater plants that are using activated sludge process and the increasing population. Non-stabilized Sewage sludge is an environmental nuisance due to high level of pathogens, offensive odours, insect attraction and potential water sources pollution. The Haifa region itself, where the study took ...

  • From Waste in Anodising Plant to New Chemical Product in Sewage Treatment Plants

    Aluminium containing caustic soda used as a pickling agent in the pre-treatment of aluminium before anodising and aluminium containing sulphuric acids used as electrolytes for the formation of oxide layers in anodising plants can be utilised in municipal sewage treatment plants to reduce phosphates and improve precipitation. From the anodiser's point of view, these products are spent once they ...


  • Thermodynamic analysis and assessment of a municipal wastewater treatment system: a field study on sewage treatment

    This paper is a field study on thermodynamic analysis and assessment of an actual municipal wastewater treatment facility. The system operation is described and a methodological approach based on the energy and exergy analyses is provided to assess the performance of a complex wastewater treatment system. Since the specific exergy value of the sludge is increased through treatment process, a new ...

  • Co-digestion of press liquids of source-sorted municipal organic waste in anaerobic sludge treatment of municipal wastewater treatment plants

    This paper describes a semi-continuous laboratory-scale investigation of a potential co-substrate for mesophilic anaerobic sludge digestion in a municipal wastewater treatment plant. A feed liquid produced from source-sorted municipal organic waste by pretreatment with a screw press was subjected to the investigation. Quantities produced in press trials as well as the composition of the feed ...

  • Pyrolysis properties of municipal sewage sludge with ZnCl2 activation under the N2 atmosphere

    The municipal sewage sludge with ZnCl2 activation was pyrolysed to obtain useful porous adsorbents. The thermogravimetric analysis and FTIR methods were used to work out the properties of dried sewage sludge with ZnCl2 activation from the Changsha secondary wastewater-treatment plant. The experimental results showed that three stages of weight loss were observed under the heating rates of ...
