  • Mechanical biological treatment for municipal solid waste

    A major portion of municipal solid waste (MSW) is dumped in unsanitary landfills in India. To protect the environment, there is an urgent need to develop a technology which could handle the increasing MSW quantities and enhance resource recovery. Mechanical biological treatment (MBT) is considered a potential method for dealing with heterogenous MSW. Proper mechanical sorting can make the ...

  • Do You Need a Microfiltration or Ultrafiltration Membrane System for Your Plant?

    Determining whether or not an industrial plant needs a microfiltration (MF) and/or ultrafiltration (UF) membrane system isn’t always as straightforward as it seems. While these systems are not essential for every industrial process, when thoughtfully implemented within an intake, process, or waste stream, they can go a long way in improving a facility’s efficiency and/or cutting ...

  • Defining solid waste

    Simultaneous to the publication of the final National Emission Standards for Hazardous Air Pollutants for Boilers (the Boiler NESHAP) and the Commercial and Industrial Solid Waste Incinerator (CISWI) Rules, EPA issued a new regulation that for the first time defines what materials are a non-hazardous solid waste when combusted. This rule, Solid Wastes Used as Fuels or Ingredients in Combustion ...

  • Waste Treatment

    Introduction The Department of Energy's (DOE) Waste Management program directs the storage, treatment, and disposal of waste generated by DOE's activities. In support of this mission, the Waste Management program uses a variety of treatment technologies to change the characteristics of the waste so that it may be more easily managed. What Is Waste Treatment? ...


  • Evaluation of a sequential aerobic?anaerobic treatment of municipal solid waste in a bioreactor landfill

    A sequential aerobic-anaerobic bioreactor landfill was operated and monitored over a period of 184 days. The bioreactor was filled with 120 kg of organic fraction of Municipal Solid Waste. Leachate recirculation was applied. The results showed rapid degradation of organic matter with rapid settlement during the aerobic period. The initial COD and BOD5 were ...

  • Assessment of leachates from a Cuban municipal solid waste landfill: characterisation and treatment

    Calle 100 landfill receives 75% of the solid waste of Havana. In this work, the physical-chemical and microbiological evaluation and the treatment of its leachates was carried out. The study of the elimination of pollutants was carried out at laboratory scale. The characterisation showed an important content in organic substances of high molecular weight, fulvic and humic acids that have a ...

  • Effect of co-managing organic waste using municipal wastewater and solid waste treatment systems in megacities

    A model was developed to calculate the mass and heat balances of wastewater and municipal solid waste treatment plants when these plants operate either separately or together with a mutual dependence on mass and energy. Then the energy consumption, life cycle costs (LCCs), greenhouse gas (GHG) emissions and effluent quality were evaluated under various scenarios to identify the most effective ...

  • Waste Water Treatment Plants

    In 1980, Los Angeles began exploring alternatives to control the H2S concentration in the digester gas produced at the Hyperion Waste Water Treatment Plant (WWTP), which treats nearly 420 MGD, wastewater generating over 475 tons of raw sludge per day. The digester gas H2S concentration had to be controlled so that the SOx emissions from the on-site combustion of the gas could be kept within ...

  • New model of municipal solid waste management

    In the current scenario, the waste is an indicator of socioeconomic development. So, the more booming economy is, the greater the volume of produced waste. The downside of this scenario is the result of technological bottlenecks of conventional management models. In this context, this paper discusses and proposes a new model for urban solid waste (USW) management, based on the ...

  • STEP - System for Solid and Liquid Waste Put to the Test

    Wendy Laursen details the System for Environmental Protection (STEP) system which is being installed inside a twenty-foot ISO container to be trialled onbard the Canadian Coast Guard vessel, Pierre Radisson.   The STEP container houses Terragon's single-drum Micro-Auto Gasifciation System (MAGS) and Wastewater Electrochemical Treatment Technology (WETT).  MAGS aims to ...

  • Status of municipal solid waste management system in India

    Municipal solid waste management (MSWM) has become a worldwide concern and is a major issue especially in developing countries due to environmental problems, such as air, soil and water pollution and generation of greenhouse gases from open dumping sites. The MSW management is going through a critical phase due to the non–availability of suitable facilities to treat and dispose of the increasing ...

  • Co-composting of sewage sludge and municipal solid waste

    Israel production of sewage sludge and MSW grows each year due to the increasing number of modern Wastewater plants that are using activated sludge process and the increasing population. Non-stabilized Sewage sludge is an environmental nuisance due to high level of pathogens, offensive odours, insect attraction and potential water sources pollution. The Haifa region itself, where the study took ...

It was shown that by changing the operation conditions from combustion to gasification the amount of evaporated Zn can be ...

  • 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 ...
