  • Separation

    Introduction: Ex situ separation can be performed by many processes. Gravity separation and sieving/physical separation are two well-developed processes that have long been primary methods for treating municipal wastewaters. Magnetic separation, on the other hand, is a much newer separation process that is still being tested. Gravity Separation Gravity ...

  • Towards municipal solid waste source separation at the household level in Accra, Ghana

    Municipal solid waste source separation at the household level has been endorsed as the way forward by all stakeholders in the waste management sector in Ghana. The study using waste stream analyses and laboratory investigations assesses the feasibility of this intervention in the Accra Metropolitan Area which has been divided into three income zones. The mean waste percentage composition was ...

  • Municipal solid waste - waste to energy conversion in India: an overview

    Municipal solid waste (MSW) is generated in enormous quantities, in India, causing environmental problems. It is collected primarily by sweeping in India and dumped on the outskirts of urban areas, which pollute the environment. Such MSWs also release methane and carbon dioxide, which are important greenhouse gases. MSW comprises biodegradable material. The MSW disposal methods in India mainly ...

  • The Power to Separate

    Gravity separators are effective and economical tools used to process wastewater and stormwater by removing pollutants such as sediment, hydrocarbons and debris through the process of sedimentation or flotation. Most separators have few or no moving parts, are easy to maintain and have a successful history of use in many different industrial, commercial and residential applications. Specifying ...

  • New guidelines for characterization of municipal solid waste: the Portuguese case

    This report proposes a new set of guidelines for the characterization of municipal solid waste. It is based on an analysis of reference methodologies, used internationally, and a case study of Valorsul (a company that handles recovery and treatment of solid waste in the North Lisbon Metropolitan Area). In particular, the suggested guidelines present a new definition of the waste to be analysed, ...

  • Wastewater treatment for a municipality

    Description of the plant At first, wastewater is pre-treated by a combinated sand and fat trap before further treatment is affected by a special screen. The accruing particles are collected in anti-septic plastic bags to avoid any personal contact because of hygienic reasons. Based on the high varying hydraulic amount of wastewater, an aerated mixing and balancing reactor is ...

  • Extraction of fuel from municipality solid wastes using an updraft gasifier

    In Bangladesh, cities are confronted with the problem of how to dispose large quantities of municipal solid waste (MSW). Gasification is a process that uses heat, pressure and steam to convert materials (MSW) directly into a gas composed primarily of carbon monoxide and hydrogen. The main objectives of this paper are: 1) to study gasification processes; 2) to design, fabrication and performance ...

  • Mesophilic and thermophilic anaerobic digestion of source-sorted municipal solid waste

    A change in existing collection systems for household waste is presently in progress in many Swedish municipalities. The objective is to separate the decomposable fraction from non-biodegradable waste in order to facilitate biological treatment and recycling of nutrients. The main reason for this development is the effort to replace landfilling of nutrient-rich, wet organic waste with sustainable ...

  • 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 ...

  • Plastics Separation In Compost

    Operators say their number one contamination problem is plastic small, large and in-between - in the compost feedstock and thus in the end product. New study and equipment offer some excellent solutions. An air separation unit from Hawker Corp. is attached to the outfeed conveyor of a screen. Plastic is collected in a tube sock (inset) attached to the fan assembly. PRESSURE in Europe to increase ...

  • Anaerobic fermentation of organic solid wastes: volatile fatty acid production and separation

    Anaerobic fermentation of organic municipal solid waste was investigated using a leach-bed reactor (LBR) to assess the volatile fatty acid (VFA) production efficiency. The leachate recycle rate in the LBR affected the VFA composition of the leachate. A six-fold increase in the recycle rate resulted in an increase of the acetic acid fraction of leachate from 24.7 to 43.0%. The separation ...

  • Environmental efficiency of composting versus anaerobic digestion of separately collected, organic waste

    Environmental policy in the Netherlands among others aims at closing material cycles and minimising the amount of waste requiring final disposal. In this policy the highest priority is given to the prevention of waste production followed by (in descending order of preference) reuse, incineration with energy recovery and sanitary landfilling. In the implementation of this solid waste policy also ...

  • Cellulose recovery from municipal wastewater

    During Aquatech 2015 the Dutch technology developer Brightwork set in the spotlight the recovery of cellulose from waste water. The project Cellulose Assisted Dewatering of Sludge (CADoS) aims at separating cellulose fibres from toilet paper from waste water using finescreening technology. After separation the fibres serve as a filter aid for effective dewatering of biological sludge. The ...

  • Source separation trends in the UK

    THE past 15 years have seen significant investment and development of the biowaste collection and treatment industry in the United Kingdom (UK), which has gone from virtually zero to an industry worth over £160 million (264.6 million USD). Driving this investment have been a number of regulatory and fiscal measures such as the first set of Landfill Directive targets due in 2010. Since 1999, the ...
