  • The impact of advanced digestion on incineration of sewage sludge

    Abstract Traditionally, when incineratin sewage sludge, it was preferable to burn raw undlgested sludge, as digestion - by extracting some of the energy from sludge- subsequently reduce its calorific value. However, when considering incineration as part of a wider strategy, the desicion whether or not to include digestion becomes less clear. Since, virtually all of the requirements of ...

  • Investigation of the effects of temperature and sludge characteristics on odors and VOC emissions during the drying process of sewage sludge

    Sludge drying is a necessary step for sludge disposal. In this study, sludge was collected from two wastewater treatment plants, and dried at different temperatures in the laboratory. The emission of odor and total volatile organic compounds (TVOCs) during the sludge drying process were determined by an online odor monitoring system. The volatile organic compounds (VOCs) in off-gas were analyzed ...

  • Phyto-dewatering of sewage sludge using Panicum repens L.

    Experiments in the field environment have been conducted to study the growth of Panicum repens L., an aquatic plant, in the sewage sludge matrix. The experiments were also carried out to investigate the ability of this plant to dewater sewage sludge to increase the capacity of conventional drying beds. In addition, the ability of Panicum repens L. to reduce the sludge ...

  • 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 ...

  • 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 ...

  • Assessment of existing and future sewage sludge characterisation in the Gaza Strip, Palestine

    The three wastewater treatment plants in Gaza Strip, Palestine, rely on old technologies that have proved to be unable to solve the existing problems. Sludge management is not currently considered in detail in Palestine and the area will face challenges of sludge management in the near future after the construction of ongoing and planned projects in the Gaza Strip. The paper focuses on the ...

  • Performance of a system with full- and pilot-scale sludge drying reed bed units treating septic tank sludge in Brazil

    This study investigated the performance of sludge drying reed beds (SDRB) at full- and pilot-scale treating sludge from septic tanks in the city of Belo Horizonte, Brazil. The treatment units, planted with Cynodon spp., were based on an adaptation of the first-stage of the French vertical-flow constructed wetland, originally developed for treating sewage. Two different operational phases ...

  • Environmental and economic assessment of municipal sewage sludge management – a case study in Beijing, China

    A case study was conducted in Beijing to identify municipal sewage sludge (SS) management systems appropriate for a sound material-cycle society. The environmental and economic impacts of four realistic SS-handling scenarios were investigated: stabilization by thermal drying, increased inclusion of SS in cement manufacture, and using either dried or carbonized SS as substitute fuel for ...

  • Nitrogen Recovery from Sewage Sludge - Case Study

    Ammonium Sulphate from process air The air with which the compost from sludge processor GMB BioEnergie is aerated in the biological drying tunnels contains a lot of ammonia. The emission of this ammonia-rich air led to odor complaints in the past. Now we see this air as a source of nutrients. We pass the air through an air scrubber with sulfuric acid. This sulfuric acid binds the ammoniacal ...

  • Life Cycle Assessment of an intensive sewage treatment plant in Barcelona (Spain) with focus on energy aspects

    Life Cycle Assessment was used to evaluate environmental impacts associated to a full-scale wastewater treatment plant (WWTP) in Barcelona Metropolitan Area, with a treatment capacity of 2 million population equivalent, focussing on energy aspects and resources consumption. The wastewater line includes conventional pre-treatment, primary settler, activated sludge with nitrogen removal, and ...

  • Methodology for the assessment of the greenhouse gas impact of wastewater sludge treatment

    Nitrous oxide (N2O) and methane (CH4) emissions from the wastewater sector represent the second largest source of greenhouse gas (GHG) emissions of the waste sector. A protocol has been developed to measure GHG from sewage sludge treatment. GHG measurements were performed on two industrial sewage sludge composting plants. Measurement campaigns showed GHG emissions range between 0.18 to 3.40 ...

  • Transportation of digested sludges over extreme distances

    Sludge is a residual product of sewage treatment that, as a rule, is digested and concentrated. In larger processing plants, it is dehydrated, partially dried and subsequently utilised in other processes. This usually takes the form of incineration and subsequent use as an additive to building materials by the cement industry. In the sewage treatment plant (STP) of the local authorities ...

  • Environmental assessment of different dewatering and drying methods on the basis of life cycle assessment

    Sewage sludge is an inevitable product of wastewater treatment in municipal wastewater plants and its amount has increased dramatically due to the growing number of sewage systems users. This sludge needs to be adequately treated in order to decrease its hazardous properties and any negative influence on the environment. In this paper, gate to gate analysis, on the basis of life cycle assessment ...

  • Energy potential and alternative usages of biogas and sludge from UASB reactors: case study of the Laboreaux wastewater treatment plant

    This work assessed the energy potential and alternative usages of biogas and sludge generated in upflow anaerobic sludge blanket reactors at the Laboreaux sewage treatment plant (STP), Brazil. Two scenarios were considered: (i) priority use of biogas for the thermal drying of dehydrated sludge and the use of the excess biogas for electricity generation in an ICE (internal combustion engine); ...
