  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • 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 ...

  • Methods of Purification by Water Innovations, Inc.

    Carbon Filtration is used for several reasons. Its primary purpose is the reduction of chlorine to less than 0.1 ppm. Chorine can damage softener resins, reverse osmosis membranes, and mixed bed deionization resins. Activated carbon will also help control tastes and odors, provide organic and hazardous organic chemical reduction, and some particulate reduction. ...

  • 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 ...

  • Robust corona-electrostatic separation method for solid waste recycling

    The objective was to reduce variation in the outcome of a corona-electrostatic separation process for solid waste recycling by finding operating conditions (high-voltage level, roll speed, splitter position) under which uncontrollable variation in 'noise factors' (ambient humidity, metal content in the feed) has minimal impact on the quantity and the quality of the recovered products. The samples ...

  • Specific Technologies for Separation of Recyclable Materials From Municipal Solid Waste (MSW), Applicable in Bucharest - Romania

    Urban waste usually comes from household and public activities that mean private lodgings, shops, hotels, restaurants, offices, etc. Taking into consideration the year 2000 as a standard level, we estimate about 11,200 t/day of urban waste to be produced in Romania, from which about 2,200 t/day only in ...


  • Equipment List for full solids manage & drilling waste

    Solids Handle & drilling waste management are pretty important for drilling contractor. If they manage this division well, they can save lots of money on drilling mud / drilling chemicals, also they can be environmental friendly. There is much equipment needed for solids control & drilling waste ...


  • Investigation the potential of recycling urban solid wastes

    Recycling is a solution to control the problem of managing urban solid wastes such as incineration and sanitary landfill. It consists re-processing of products and materials, which have been consumed several times. The methods which are presently used for recycling and processing the wastes of Ardakan City consists of collection by wastes collectors, separation by urban service labors and ...


  • Municipal Solid Waste – Key to a Low Carbon Economy

    A newly released report has found the waste sector has a key role to play in the development of a low carbon economy and the reduction of greenhouse gases (GHGs). This report comes in advance of the UN Climate Conference in Paris, which will take place in December. The report 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 ...

  • Recycling of plastic waste by density separation: Prospects for optimization

    A review of existing industrial processing and results of alternative processing investigations for separating solid mixtures and specifically recycling plastic waste by density separation is presented. Media density separation is shown to be fundamental for separation and/or pre-concentration in the recycling of plastics. The current use of static media processes limits the capacity and size of ...

  • A smarter approach to solids control

    When looking at technical brochures and marketing materials in regards to solids-control equipment, one question that should always come to mind should be: Is this really necessary? Other great questions to ask are: What are my day-to-day needs; and what are my severe, high-duty needs? Finding the right solidscontrol equipment is much like buying a personal automobile. Most vehicles’ ...

  • 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 ...

  • Solid Waste Management: A Case Study of National Refinery Limited

    Investigations have been carried out to assess and characterize the waste being generated in one of the largest petrochemical refinery of Pakistan. It was found that the refinery complex generates about 2000 metric tons of solid waste and about 0.55 million gallons of waste water per day. Besides these gaseous pollutants like H2S, CO, CO2 NO2, and particulate matter are also emitted in the ...


  • Application of LCA to support solid waste management policy in Phuket

    Life Cycle Assessment (LCA) is employed to evaluate the environmental performance of the existing Municipal Solid Waste (MSW) management system in Phuket and compared with different possible alternative Integrated Waste Management Systems (IWMSs). The results show that the scenario comprising source separation of waste for anaerobic digestion and recycling plus incineration (with energy recovery) ...
