  • Minimization of Major Air Pollutants from Sewage Sludge Fluid Bed Incinerators

    ABSTRACT Emissions of major air pollutants including carbon monoxide (CO), nitrogen oxides (NOx) and mercury (Hg) were studied at two sewage sludge fluidized bed combustion (FBC) plants. Both the North West Bergen (NWB) County Utility Authority and the Little Miami (LM) plants have air pollution control systems (APCS) that are of the wet type. Various operating conditions such as temperature, ...

  • Dissolved-air flotation associated with an anaerobic reactor, as applied to sewage treatment

    This paper presents the results of a study performed with a pilot sewage treatment plant consisting of an aerobic reactor followed by a flotation unit. To coagulate the anaerobic effluent, different ferric chloride dosages were applied by adopting two approaches: applying constant dosages during the essay and varying the dosages according to the anaerobic effluent turbidity. To obtain more than ...

  • Co-fermentation of sewage sludge and biowastes

    The anaerobic treatment of sewage sludge has a long history in Germany. It began early in the Twentieth Century with the development of the Imhoff tank and has, since then, been con-tinuously further developed. Today, anaerobic sludge digestion is the most widely used process for stabilizing sewage sludges. Digesters, in which a portion of the sewage sludge is converted into utilizable biogas ...

  • Compact sewage system offers trouble free operation

    The toilets, which are located directly beneath Southport’s tourist information centre, are open 24 hours, but notattended at night. This has resulted in abuse of the drainage system, with drink cans and hypodermic needles regularly found in the sump. The compressed air operated sewage ejector system previously installed beneath the toilets, could not cope with this abuse and required expensive ...

  • Achieving nitrification in sewage lagoons with an innovative floating RBC

    The research involved the newly developed floating rotating biological contactor (FRBC), a unique unit consisting of a rotating cage filled with hollow, spherical packing of injection molded plastic. The cage rotates to provide biomass a chance to contact both substrate and air. A partially mixed three-cell aerated lagoon was selected for the study. The lagoon received about 114 m3/d of domestic ...

  • Behaviour and adsorptive removal of siloxanes in sewage sludge biogas

    We investigated the behaviour of siloxanes, which adversely affect biogas engines, as well as their concentration levels in sewage sludge biogas in Japan. We also performed experiments on the absorptive removal of siloxanes using various adsorbents and determined the main adsorbent characteristics required for the removal of siloxanes. The results of our study on the concentration and composition ...

  • Factors Affecting Disinfection and Stabilization of Sewage Sludge

    ABSTRACTEffective disinfection and stabilization of sewage sludge prior to land application is essential to not only protect human health, but also to convince the public of its benefits and safety. A basic understanding of the key factors involved in producing a stable biosolid product is a necessary component to ensuring that effective disinfection and stabilization are achieved. Key stressors ...

  • 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 ...

  • Factors affecting decay of Salmonella Birkenhead and coliphage MS2 during mesophilic anaerobic digestion and air drying of sewage sludge

    Factors affecting the decay of Salmonella Birkenhead and coliphage, as representatives of bacterial and viral pathogens, respectively, during mesophilic anaerobic digestion (MAD) and air drying treatment of anaerobically digested sewage sludge were investigated. Controlled concentrations of S. Birkenhead were inoculated into non-sterile, autoclaved, γ-irradiated and ...

  • Sensitivity analysis for the SimpleTreat model to simulate fate of chemicals in sewage treatment plants

    SimpleTreat 3.1 predicts the distribution and elimination of chemicals by sewage treatment. The model is used as the default calculation in EUSES 2.0 to estimate exposure concentration in the receiving water, soil and air. A sensitivity analysis was performed to rank input parameters according to their influence on model predictions. Triclosan was selected for the base case. The sewage flow, ...

  • Solar drying of sewage sludge - An old method with modern technology using Wendewolf®

    Any Sewage Water Work throughout the world will produce sludge, a form of biomass growing in the basins. This biomass has to be evacuated and is, generally speaking difficult to handle! When liquid it has a dry matter of 3 to 4 %, or only 30 to 40 kg per ton of sludge, when mechanically dehydrated to 20 - 25 % most of it is still water, as an average  750 to 800 kg per ton of filter cake. ...
