  • Study on sewage sludge gasification

    Aimed at creating new technology to reduct greenhouse gas emission, the Tokyo Bureau of Sewerage has developed a system generating electricity with a gas engine using biogas generated by pyrolytic gasification of sewage sludge in a fluidized-bed gasifier. A 15t/d demonstration facility was built based on a dehydrated sludge and demonstration tests were run for 3400 hours from 2005. As a result of ...

  • Fate of indicator endocrine disrupting chemicals in sewage during treatment and polishing for non-potable reuse

    The removal and fate of several indicator endocrine disrupting chemicals (EDCs) at two large municipal wastewater treatment plants (WWTPs) in Adelaide South Australia was investigated. Non-estrogens included the non-ionic surfactant breakdown compounds nonyl phenol mono- and di-ethoxylates, 4-t-octylphenol and 4-nonyl phenol; and, the plasticizer bisphenol A. Estrogens included 17β-estradiol; ...

  • Non-linear modeling using fuzzy principal component regression for Vidyaranyapuram sewage treatment plant, Mysore – India

    Fuzzy principal component regression (FPCR) is proposed to model the non-linear process of sewage treatment plant (STP) data matrix. The dimension reduction of voluminous data was done by principal component analysis (PCA). The PCA score values were partitioned by fuzzy-c-means (FCM) clustering, and a Takagi–Sugeno–Kang (TSK) fuzzy model was built based on the FCM functions. The ...

  • Evolution of the sewage treatment plant model SimpleTreat: Applicability domain and data requirements

    SimpleTreat 3.1 is the sewage treatment plant (STP) model implemented in the EU framework for the environmental risk assessment of chemicals. The model was originally designed for neutral hydrophobic chemicals, while many substances currently under regulatory scrutiny, are ionisable at environmental pH. Although the model has been adapted to describe ionisation (SimpleTreat 3.1), the fate of ...

  • Treatment of sewage sludge using super critical water oxidation-an up date

    Supercritical water oxidation (SCWO) is an innovative, economic and incredibly effective destruction method for organic wastewater and sludge and is a realistic alternative to conventional methods. From 1998 to 2007 extensive evaluations of the destruction of sewage sludge by SCWO were performed by Chematur Engineering AB on two state of the art pilot plants. These units had capacities of 250 ...

  • Sewage sludge treatment: evaluation of the energy potential and methane emissions with COD balancing

    Sewage sludge is an important resource for the generation of electricity and heat within a wastewater treatment plant (WWTP). Taking a holistic approach to such use involves considering the greenhouse gas emissions. In particular, for anaerobic sludge treatment, methane emissions are a matter of concern. Therefore, the utilization of a carbon balance, based on the chemical oxygen demand (COD), ...

  • Sewage Treatment - Klargester is the market leader for small and medium-sized domestic treatment plant and waste water treatment systems in the UK

    Sewage treatment plant operate by providing an environment in which aerobic bacteria are cultured. These bacteria survive by using biological matter in the sewage as a food source. To provide optimum treatment the bacteria need free access to oxygen and immersion in the sewage effluent. The majority of package plant work by providing a fixed medium that the bacteria adhere to, and a means of ...

  • 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, ...

  • Treatment of the city of Oudenaarde (Belgium) sewage discharge canal case study

    Executive Summaryc A canal responsible for carrying sewage away from the City of Oudenaarde to the Scheldt River was partially dammed in 1965 leaving an area of open water of approximately 1 hectare (600 meters by 17 meters). As the canal was only partially dammed, water from the canal continued to flow into the Scheldt River. Two large municipal sewage collection discharge pipes ...
