  • 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 ...

  • Management of sewage sludge and ash containing radioactive materials

    Approximately 50% of the seven to eight million metric tonnes of municipal sewage sludge produced annually in the US is reused. Beneficial uses of sewage sludge include agricultural land application, land reclamation, forestry, and various commercial applications. Excessive levels of contaminants, however, can limit the potential usefulness of land-applied sewage sludge. A recently completed ...

  • 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 ...

  • 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 ...

  • A review on sludge dewatering indices

    Dewatering of sludge from sewage treatment plants is proving to be a significant challenge due to the large amounts of residual sludges generated annually. In recent years, research and development have focused on improving the dewatering process in order to reduce subsequent costs of sludge management and transport. To achieve this goal, it is necessary to establish reliable indices that ...

  • Development of a tool for improving the management of gaseous emissions in UASB-based sewage treatment plants

    This study aimed at developing a simple tool for improving the management of gaseous emissions in UASB-based sewage treatment plants (STPs), considering different scenarios for the management of sludge, biogas and gaseous emissions (especially sulfide and methane). For small STPs (<10,000 inhab.), simple alternatives for the use of biogas were considered (e.g. for excess sludge ...

  • Sewage sludge minimisation by means of wet oxidation: process performance and economic sustainability

    Today, several technologies and management strategies are proposed and applied in WWTPs to minimise sludge production and contamination and their techno–economic feasibility has to be carefully evaluated. In this work (which is being conducted within the European Union project 'ROUTES'), based on bench results, a mass balance was drawn for a WWTP (500,000 PE), where it was supposed to install a ...

  • Municipal sewage application (Nagano Prefecture) case study

    Squeeze sludge fresh out of the reactor. Don't wait until it stinks! In the wastewater treatment plant of a town in Nagano, the long-used belt press was in a time to be overhauled. The person in charge had racked his brain over the problem of huge cost required to overhaul this equipment at regular intervals. He had been seeking a solution to this problem. In addition, he had to cope ...

  • Pyrolysis properties of municipal sewage sludge with ZnCl2 activation under the N2 atmosphere

    The municipal sewage sludge with ZnCl2 activation was pyrolysed to obtain useful porous adsorbents. The thermogravimetric analysis and FTIR methods were used to work out the properties of dried sewage sludge with ZnCl2 activation from the Changsha secondary wastewater-treatment plant. The experimental results showed that three stages of weight loss were observed under the heating rates of ...

  • Evaluation of gamma irradiation for bio-solid waste management

    Gamma irradiation is a form of pure energy which is currently used most widely for food and waste irradiation. To evaluate the potential of gamma irradiated sludge for its suitability as a soil amendment in agriculture, field experiments were carried out in a root crop, carrot (Daucus carota). Treatments consisting of three sources of manure (Farmyard Manure (FYM), gamma-irradiated sewage sludge ...

  • Saline sewage treatment and source separation of urine for more sustainable urban water management

    While energy consumption and its associated carbon emission should be minimized in wastewater treatment, it has a much lower priority than human and environmental health, which are both closely related to efficient water quality management. So conservation of surface water quality and quantity are more important for sustainable development than green house gas (GHG) emissions per se. In this ...

  • The increasing importance of assessing toxicity in determining sludge health and management policy

    The harm caused by toxic industrial effluents to sewage treatment works, has been recognised for many years. These can cause reduction in biodegradable efficiency, with an associated requirement for longer treatment time, and in extreme cases, toxic shock can kill off the secondary tanks. Currently, the presence of harmful industrial effluents is made evident by their effects ...
