  • The Municipal Water & Sewage Treatment Sector

    The best reason for the use of Albin Pump Hose pumps in this industry is the low maintenance of the pump. This industry readily accepts an average hose life of 1.500 - 3.000 hours in continuous duty and this hose life will provide much lower maintenance costs and repair time than with other pumps. Basic Pump Requirements For operation in an automatic system the following would ...

  • 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 ...

  • Purification of domestic sewage by water-hyacinth (Eichhornia crassipes)

    Sewage management is posing serious techno-economic problems in cities, particularly in developing countries. A new technology, sewage purification by water-hyacinth (Eichhornia crassipes), is a possible solution. This paper studied the suitability and effectiveness of water-hyacinth in treating domestic sewage. A 28-day experiment was performed under a controlled environment of a screen-house ...

  • Chemical fingerprinting of saline water intrusion into sewage lines

    High salinity in sewage sludge can affect not only the operation of wastewater treatment plants (WWTPs) but also the quality of treated water generated, thereby limiting its downstream reuse. Using data on geochemical parameters, both for the central WWTP in Abu Dhabi, UAE, and literature values for potential regional saline water sources (e.g., shallow groundwater and regional Arabian Gulf ...

  • Supercritical water oxidation of sewage sludge – state of the art

    Supercritical water oxidation (SCWO) is an innovative and effective destruction method for organic wastewater and sludge. Several tests of the destruction of sewage sludge by SCWO have been done at two state of the art pilot plants. These units have capacities of 250 kg/h and 1100 kg/h, respectively. The test results show that the technology easily destroys the organic material in the sludge 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 ...

  • Sewage treatment plant

    BONO ARTES has developed an activated sludge process called BIOCLAR, which is a great technological step forwards compared to conventional methods. A large part of civil and industrial installations, especially in developing countries, is located in remote and secluded areas where there is no possibility for connection to a public sewer. On the other hand, the minimisation of the impact on the ...

  • Austrian municipal sewage plant

    The sewage work of the borough Deutsch-Wagram is situated in the south west of the settlement on the left shore of the Ru§bach and is in operation since 1969. The drainage area is 350 hectare and the degradation performance is more than 90%. All accumulated waste water is cleaned by mechanical, chemical and biological treatment. At the moment only one activated sludge tank is used, the second one ...

  • Water recovery from sewage using forward osmosis

    This research is part of the Sewer Mining project aimed at developing a new technological concept by extracting water from sewage by means of forward osmosis (FO). FO, in combination with a reconcentration system, e.g. reverse osmosis (RO) is used to recover high-quality water. Furthermore, the subsequent concentrated sewage (containing an inherent energy content) can be converted into a ...

  • 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 ...

  • Sewage treatment plant case study

    Contributing to snowy regions in which the transportation of sludge is difficult In municipal wastewater treatment plant in snowy regions, snow-bound in winter, taking dewatered cake out regularly is sometimes difficult. Two problems were also presented in this municipal wastewater treatment plant, i.e., the difficulty of taking sludge out using carriers in winter, which had been ...

  • Climate change a threat to sewage systems

    Many cities could face problems with their sewage in the future. A research study for Stockholm shows that a change in precipitation, combined with a population increase, could bring disruptions as early as the middle of the century. Climate change could put more pressure on the sewage systems in the future. Climate scenarios indicate critical factors such as increased volumes of rain and rising ...

  • Surveillance of Influenza A and the pandemic influenza A (H1N1) 2009 in sewage and surface water in the Netherlands

    The role of the water cycle in spreading human pathogenic influenza viruses is poorly studied and is not considered to be significant. However, gastrointestinal symptoms developed in a large proportion of influenza A (H1N1) 2009 virus infected people during the pandemic in 2009 and fecal shedding was reported. This fecal route could potentially play a role in the entry of human pathogenic ...
