  • 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 ...

  • Biosorptive separation of 'labile' fractions of copper and lead from river sediments and evaluation by differential pulse, anodic stripping voltammetry

    The 'labile' copper and lead metal contents of contaminated sediments were extracted in different chemical solutions and then subjected for biosorptive separations. The sorbents called 'AlgaSORB-sp' and 'AlgaSORB-ch' were derived from two different algae, viz., Spirogyra and Chlorella, respectively . The metal detection was made by differential pulse, anodic stripping voltammetry. The retention ...

  • Sequential fractionation of phosphorus in lake sediments of Northern Greece

    The amounts and forms of potentially mobile P in surface sediments from two lakes, Volvi and Koronia, located in Northern Greece were evaluated using a sequential chemical extraction. Five sedimentary P reservoirs were separately quantified: loosely sorbed P (NH4Cl-P), iron associated P (BD-P), calcium bound P (HCl-P), metal oxide bound P (NaOH-P) and residual P (organic and refractory P). ...

  • REDWAVE Metal Days 2015 - Review

    The REDWAVE Metal Days, at BT-Wolfgang Binder in Gleisdorf, pro­vided the context for international experts from various sectors of the metal and aluminium recycling in­dustry to exchange information on markets, technologies and practical experience. In addition, the new REDWAVE XRF-M sorting system, for recycling in the metals sector, was presented to the participants. ...

  • Bioavailability of purified subcellular metals to a marine fish

    In this study, we took advantages of the supply of naturally contaminated oysters and investigated how the subcellular metal distribution and the metal burden in prey affected the transfer of metals to a marine fish, the grunt Terapon jarbua. The oysters Crassostrea hongkongensis with different contaminated histories were collected and separated into three subcellular fractions (metal‐rich ...

  • Building waste and ballistic separator - a worthwhile matter

    Efficient sorting for sustainable recycling instead of just pure disposal. That is the motto for dealing with building waste.  What do you understand by the expression building waste? This is a collective expression for the diverse types of waste that occur on building sites. This includes mixtures of mineral and non mineral materials (e.g. stone mixed with wood, sheets of ...

  • Impact of heavy metals on the oil products biodegradation process

    Oil products continue to be used as a principal source of energy. Wide-scale production, transport, global use and disposal of petroleum have made them major contaminants in prevalence and quantity in the environment. In accidental spills, actions are taken to remove or remediate or recover the contaminants immediately, especially if they occur in environmentally sensitive areas, for example, in ...

  • A Comparison Between Systems for Source Separation of Organic Household Waste

    Conventional collection of source separated waste using separate containers was com-pared to collection in bags with different colours and optical sorting (OptiBag). Purity was found to be high, especially in the OptiBag system. However the conventional system had new instructions for sorting, which may have influenced the result. Sources for heavy metals are identified as waste metal fraction, ...


  • Separating micropollutants from biowastes using anaerobic treatment facilities

    Recycling of municipal organic wastes from separate collection systems becomes more and more important in the Federal Republic of Germany. Experiences gathered during the last few years indicate that the recovery potential of waste and biosolids strongly depends on quality of the produced composts or their pollutant load. This means that only really low polluted composts will be competitive in ...

  • Study of colloidal content and associated heavy metals in landfill leachate: a case study of El-Akader landfill site: Jordan

    Landfill leachate samples were collected anaerobically at six locations at the El-Akader landfill site in North Jordan. The collected leachate samples were separated into size fractions with special attention to the distribution of colloids and associated heavy metals. The fraction sizes were 1.2 µm. The maximum concentrations of heavy metals in the analysed leachate samples were Cd 0.6 µg/l, Ni ...

  • Austin AI QXR-M – Technology to improve metal recovery from non-ferrous residues

    Existing technology has been used for some time to separate light non-ferrous alloys from heavier non-ferrous alloys; however, over the past three years, there is a significant added value in performing additional separations to recover specific high dollar alloys. Examples of such are separating pure copper from copper alloys (brass and bronze) or wrought from cast aluminum. The only way to do ...

  • Ecopark 4, Spain, trusts AUTOSORT for the efficient automation of its separation processes - Case Study

    Ecopark 4 in Hostalets de Pierola (Barcelona), part of the infrastructure of the Barcelona Metropolitan Area (AMB), uses ten of TOMRA Sorting Recycling's AUTOSORT optical separators, which currently recover 90% of sortable material. This fully automated plant has three treatment streams which process around 300,000 tons annually. Ecopark 4, located in Hostalets de Pierola (Barcelona), is a ...

  • Metals and bacteria partitioning to various size particles in Ballona Creek storm water runoff

    Many storm water best management practice (BMP) devices function primarily by capturing particulate matter to take advantage of the well‐documented association between storm water particles and pollutants. The hydrodynamic separation or settling methods used by most BMP devices are most effective at capturing medium to large particles; however, these may not be the most predominant particles ...

  • Characterisation of Incinerator Residues for Their Possible Re-Use

    MSW incineration produces a high quantity of residues (slags, fly ashes, sludges). Recycling suitability of residues is therefore an important issue requiring as a first step their physical and chemical characterisation (mass, granulometry distribution, merceology) and determination of their hazardousness (i.e. pollutant contents of heavy metals and chlorinated organic compounds). ...


  • “CO-MINGLED” SORTING WITH THE BEST EFFICIENCY

    Ballistic separators are a standard when sorting “co-mingled waste”. Even 20 years ago various experiments were carried out to try and imitate the ballistic effect with other machines. Until now the sorting quality and efficiency of the ballistic separator has not been achieved in any of the experiments with tilted conveyor belts, disk screens, banana screens, star screens and ...

  • Sorting plants for industrial waste, location: south of Germany

    Task Separation and sorting of industrial and building site waste as well as bulky refuses. Potential recyclables such as wood, paper, plastics, metals and aluminium shall no longer be sent to garbage incineration, but can be recycled after the sorting into different material fractions. Solution Conception and realisation of a complete  industrial waste ...

  • Stormwater retention basin efficiency regarding micropollutant loads and ecotoxicity

    Retention basin efficiency in micropollutant removal has not been very well studied, in particular for pollutants highlighted by the European Water Framework Directive of 2000 such as pesticides, polybrominated diphenyl ethers (PBDEs) and alkylphenols. This study is based on in situ experiments carried out on a stormwater retention basin with the aim of estimating the basin efficiency in ...
