  • 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 ...

  • WWTP Sludge reduction case study

    Introduction The City of Spring Valley, IL was seeking bioaugmentation to reduce the economic burden of sludge dredging and disposal and to evaluate the possibility of restoring the microbiological activity in the lagoon. The lagoon was flooded several times from the near-by Illinois River, which created different strata of inorganic silt/organic sludge and densely packed sludge at the ...

  • Modeling Microbial Decay in a Cannibal™ Sludge Minimization Process

     ABSTRACT To simulate a Cannibal-EBPR system, a sequencing batch reactor (SBR) operated with anaerobic and aerobic cycles was coupled with an anaerobic sidestream bioreactor, which received mixed liquor from the SBR and returned same amount of treated sludge back to the SBR. A mathematical model of the system was used to evaluate the biomass decay coefficient, b, for a control SBR ...

  • Reduced Sludge Production in BNR Systems: Reality or Myth?

    This paper compares the performance of a pilot Modified Ludzack Ettinger (MLE) process treating degritted municipal wastewater, with full-scale activated sludge plants at two towns in Southern Ontario, namely Listowel and St. Marys. At Listowel, the MLE process achieved superior effluent quality compared to the full-scale extended aeration system at a total bioreactor HRT of 20 hours versus 48 ...

  • Ammonia Stripping And Integrated Fixed-Film Activated Sludge

    The Keystone Sanitary Landfill (KSL) is located at the Keystone Industrial Park in Dunmore and Throop Boroughs, Pennsylvania. The 618 acre landfill site was originally permitted for 5,000 tons of trash per day, and recently received a permit to develop more cells to extend the operation for another 25 years at 5,000 tons per day. Landfill leachate, an inevitable by-product of landfilling, is ...

  • Land remediation & sludge processing case study

    In late 2009 the company was approached by a London based consultancy on behalf of their clients with oil and gas interests in an Eastern European country. The brief was to supply a technology that could assist in the clean-up of historical oil spills around redundant oil wells in a working oilfield. Our initial meeting led us to believe that this was a viable contract and following several ...

  • 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 ...

  • Performance of activated sludge diffusion for biological treatment of hydrogen sulphide gas emissions

    Odours from wastewater treatment plants are comprised of a mixture of various gases with hydrogen sulphide (H2S) often being the dominant constituent. Activated sludge diffusion (ASD) as a biotreatment system for odour abatement has been conducted for over 30 years but has limited broad application due to disagreement in the literature regarding the effect that ASD may have on wastewater ...

  • Pre-ozonation in the activated sludge process: fate of nitrogen species

    The objective of this research was to include ozonation prior to an activated sludge treatment and investigate the effect on the nitrogen species, their fate and the consequences of this oxidation upon the biomass. Three parallel treatment systems were used: the base system, where feed went directly to the activated sludge reactor, and two others, where the influent was ozonated at two different ...

  • Characteristics and potential uses of sewage sludge in the commercial capital of Bangladesh

    Based on contrasting properties, sewage sludge can be co-recycled in order to take simultaneously the best profit and minimise environmental pollution. The present study was conducted to assess the physical and chemical properties of sewage sludge generated from different sources in the commercial capital of Bangladesh and on the basis of these characteristics a variety of ways had been fixed to ...

  • Sludge reduction in a small wastewater treatment plant by electro-kinetic disintegration

    Sludge reduction in a wastewater treatment plant (WWTP) has recently become a key issue for the managing companies, due to the increasing constraints on the disposal alternatives. Therefore, all the solutions proposed with the aim of minimizing sludge production are receiving increasing attention and are tested either at laboratory or full-scale to evaluate their real effectiveness. In the ...

  • Quantifying the impacts of co-digesiton of waste streams with sewage sludge

    In order to slow down the impending impacts of global climate change due to consumption of fossil fuels, governments are looking at ways to develop and incentivise alternative renewable energy sources. Subsequently, the UK has imposed renewable energy targets of 15% of all energy consumption by the year 2020, but admit that – in order to meet carbon dioxide reductions of 20% by 2020 – renewable ...

  • TDS and Sludge Generation Impacts from Use of Chemicals in Wastewater Treatment

    ABSTRACTThe paper analyses theoretically expected TDS changes resulting from use of typical chemicals and from biological treatment. This is compared with the experimental data from full-scale facilities and from bench tests. Sludge generation effects are also discussed with supporting data. INTRODUCTIONWith progressively more stringent limits and expanding list of controlled parameters ...

  • Solidification / Immobilisation of sludge from physical-chemical WWT process

    In 2003 econ received an inquiry from a service company operating an industrial waste water treatment plant. At the end of the physical-chemical WWT process this client generated metal-hydroxide sludge from his chamber filter presses. Originally he discharged the sludge into skips and brought it to a hazardous waste landfill. At this landfill, a solidification process was used to stabilise ...
