  • 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 ...

  • 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 ...

  • 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 ...

  • Characterization of solid waste and determination of the emission potential

    Waste samples were taken in order to investigate the material behaviour regarding different treatment/recycling options. In waste incineration, the combustible and inert parts have to be determined. The content of biodegradable organic substances is important in biological treatment. The portion of biodegradable organic substance has also to be considered if wastes are to be landfilled. This ...

  • 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 ...

  • Recycling Zinc From Municipal Solid Waste

    Results from experiments carried out in laboratory and on a 0.5 MW test facility are presented. It was shown that Zn can be substantially extracted from waste using different techniques. In the pilot experiments the Zn behavior was investigated with radioactive tracers. It was shown that by changing the operation conditions from combustion to gasification the amount of evaporated Zn can be ...

  • Solid waste management in tabriz petrochemical complex

    Petrochemical industries, like other waste sources, are associated with numerous waste-related environmental problems. However, petrochemical solid waste is generally associated with more hazardous constituents, and accordingly carries a higher level of public health and environmental risk potential. In the last decade, the global economy has undergone radical changes that have had significant ...

  • Waste Water Treatment Processes Explained

    SUNCOAST WASTE WATER MANAGEMENT  presents  AEROBIC -verses- ANAEROBIC THE AEROBIC PROCESS There are two basic types of sewerage treatment processes, which are the Aerobic process and the Anaerobic process. Aerobic means with air or oxygen and Anaerobic (septic) means without air or oxygen. Aerobic bacteria are a higher life form and when digesting waste are utilising dissolved oxygen or air in ...

  • 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 ...

  • Solid waste industry reduces fatalities and injuries

    The most recent data from 2009 for the solid waste industry1 indicate that occupational fatalities have decreased substantially and the downward trend in days-away-from-work injuries and illnesses continues.2 These data, which are recorded by the Bureau of Labor Statistics (BLS), are encouraging. Yet the industry remains one of the top 10 most hazardous in the U.S. The total number of fatalities ...

  • 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 ...

  • 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 ...
