  • Sewage Treatment – Small System in a Watershed

    ABSTRACT:Water purveyors, in examining their watersheds, have raised concerns over small community pollution sources, particularly over phosphorus, nitrogen, pathogens and suspended solids. As our population has increasingly moved further upstream in watersheds, the application of classic sewage treatment plants (STPs) have been pushed to their limit of design, especially in light of the need by ...

  • The contribution of pharmaceutically‐active compounds from healthcare facilities to a receiving sewage treatment plant in Canada

    Concentrations and percent loadings of pharmaceutically‐active compounds (PhACs) and other emerging contaminants (ECs) released from healthcare facilities (2 hospitals and a long‐term‐care facility) to a sewage treatment plant (STP) in a large urban sewershed was evaluated. An additional hospital outside the sewershed was also monitored. Fourteen of the 24 steroids /hormones and 88 of the 117 ...

  • Energy utilization in sewage treatment – a review with comparisons

    In recent years, the operating cost of sewage treatment plants (STPs) in some parts of the world has been rising due to increases in the cost of energy. STPs have focused on energy reduction and recovery from treatment processes in order to lower energy consumption. The development involves the improvement of capital set-up for treatment plants in terms of equipment upgrading/plant sizing as ...

  • Analysis of Sewage and Sewage Sludge by Simultaneous ICP Spectroscopy

    In recent years, the development and expansion of sewage treatment facilities has resulted in increased amounts of sludge which is generated in the treatment process, and which has presented a problem due to processing of the sludge itself. Sludge is normally incinerated or solidified and then disposed of in landfills or recycled for use in construction materials such as concrete or ...

  • Case Study: Biolan Wastewater Treatment Facility

    The initial situation Biolan decided to build a new wastewater treatment plant in 2004. The treatment plant should have sufficient capacity, also taking the future into account. The requirements were to achieve a good purification result as well as removing odours from the region. The plant was designed by the company Jaakko Pöyry Oyj. The size of the main process basin turned out to ...

  • Sewage sludge management in Malaysia

    This paper describes the current status of sewage sludge management in Malaysia, including sludge characteristics from both communal sewage treatment facilities and septic tanks. The levels of potentially toxic elements in the sludge are defined and compared to levels elsewhere in the context of the suitability of the sludge for agricultural use. Current sludge disposal practices are reviewed and ...

  • 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 ...

  • The Rhizopur® process ten years on: a green solution for sewage treatment in small communities

    Ten years ago the Rhizopur® process was conceived in order to treat sewage from small towns. Since 1999 when the first Rhizopur® plant was commissioned, the number of facilities has been growing steadily and today there are more than fifty Rhizopur® facilities in France. This process combines three existing technologies, i.e. biofilm, infiltration/percolation and mineralisation in constructed ...

  • Waste Water Treatment Facility in Italy Greatly Reduces Volume with Pyrobustor®

    The ARA Pustertal wastewater treatment facility treats residential waste water from an association of 14 municipalities with a collection area of 444 square miles, corresponding to a population of approximately 400,000.  A thermal dryer reduced the volume and weight of approximately 16,000 tons/year of sewage sludge containing 20-25% dry matter. The sludge volume was reduced about ...

  • 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 ...
