  • Continuous Pyrolysis Facility for Sewage Sludge Treatment

    The amount of sewage sludge is catastrophically increased in the latest few decades due to functioning of the municipal sewage treatment facilities. Dry sewage sludge contains 70-90% of the organic substances and 10-30% of the inorganic substances, which are dangerous for human health in case of inappropriate utilization. The continuous pyrolysis technology presents the unique sewage sludge ...

  • Characterization of char from slow pyrolysis of sewage sludge

    The effects of final pyrolysis temperature Tend from 300 ºC to 550 ºC, heating rates β of 2 ºC/min, 3 ºC/min and 5 ºC/min, retention time RT from 45 min to 90 min, and the moisture content MC from 0 to 70% on characteristics of the pyrolysis char from sewage sludge were investigated using a tube furnace in this study. The resulting chars were characterized by sorption of nitrogen (surface area ...

  • Sewage sludge and waterworks sludge stabilization in sludge treatment reed bed systems

    In this study, results about sludge stabilization in sludge treatment reed bed (STRB) systems in two different systems, Hanningfield STRB 1 (England), treating waterworks sludge, and Stenlille STRB 2 (Denmark), treating surplus activated sludge, are presented. The study mainly focused on the effectiveness of the STRBs systems in stabilizing sludge organic matter; in fact, parameters correlated ...

  • Removal of hydrogen sulphide on sewage sludge/industrial sludge based carbonaceous adsorbents

    The adsorbents were prepared for sewage sludge, waste oil sludge and metal oil sludge. On the materials obtained dynamic adsorption of H2S was measured. The initial and exhausted adsorbents were characterised using sorption of nitrogen, thermal analysis, and XRF, XRD and surface pH measurements. The adsorbents have high capacity for H2S (10% wt) The high volume of mesopores contributes ...

  • 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 the energetic potential of sewage sludge by characterization of its organic composition

    The composition of sewage sludge and, thus, its energetic potential is influenced by wastewater and wastewater treatment processes. Higher or lower heating values (HHV or LHV) are decisive factors for the incineration/gasification/pyrolysis of sewage sludge. The HHV is analyzed with a bomb calorimeter and converted to the LHV. It is also possible to calculate the heating value via chemical ...

  • Heterogeneous catalytic ozonation of hydroquinone using sewage sludge-derived carbonaceous catalysts

    This study converted sewage sludge into a carbonaceous catalyst via pyrolysis and employed it in the ozonation of hydroquinone. The catalyst was characterized by Mössbauer spectroscopy, X-ray photoelectron spectroscopy, temperature programmed desorption, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction. Intermediate ...

  • Surface properties and adsorption characteristics to methylene blue and iodine of adsorbents from sludge

    Adsorbent materials created from wastewater sludge have unique surface characteristics and could be effective in adsorption applications. In this research, the sludge-adsorbents were generated by pyrolyzing mixtures of sewage sludge and H2SO4. Scanning electron microscope (SEM), thermal analysis, X-ray diffraction (XRD) and X-ray photoelectron spectroscope (XPS) were used to analyze the ...

  • A Comprehensive Review Of The Sludge Treatment Process

    It is possible to take sludge and convert this into a biofuel. This is becoming more common every single day. Businesses that have these machines are able to produce a substantial amount of revenue as long as they have a constant supply of this material. If you have a solid waste plant where you are processing this material daily, you can use this to help you generate more ...

  • Neptune Project Deliverable D2.1

    Within WP2 in the Neptune project, promising technologies were developed and further investigated for sustainable wastewater treatment, where wastewater is regarded as a resource rather than as a waste. These technologies comprise microbial fuel cells for energy recuperation, denitrification and production of added value product. For the removal of micropollutants two new technologies were ...

  • Is Waste Going to be Our Apocalypse Without a Noah’s Ark to Save Us?

    Human beings have been dumping waste in water, including the ocean, since before the Agricultural Age. The Industrial Age brought with it new materials to dump, chemical wastes and by-products. Some materials are dumped into rivers and find their way to the ocean by running downstream. Other materials are dumped directly into the ocean from boats. Plastic is a harmful pollutant that does not ...
