  • 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 ...

  • Dyed viruses and metal particles for advanced separation studies

    Single nanometer sized particles are poorly retained by conventional water treatment methods and are hardly detectable in water samples. The particles present a separate class of pollutants and their transport and fate cannot be studied by tracking bacteria, turbidity, free dyes or ions. Dyed bacteriophages and gold nanoparticles are two novel tools that facilitate the studies of virus ...

  • Separation of some heavy metal species from electroplating rinsing solutions by ion exchange resin

    A strongly basic anion exchange lewatit MP 600 resin was tested to separate metal species from electroplating rinsing wastewater. An azo resorcinol 4–(2–pyridylazo) dyestuff was used as a complexing agent. Adsorption isotherms were modelled in an ethanol/acetic acid/water media. The loaded resin is regenerated using 4 M HCl whereby the eluted metal species are recovered. Results revealed that ...

  • Copper Wire Granulator, Novel to You?

    Copper Wire Granulator is a kind of excellent waste recycling and environmentally friendly equipment used for granulating waste copper wire and separating the copper from plastic to get the pure copper granule and plastic finally. It also can be called wire granulator / cable granulator ...

  • In the Works: Magnetic Plastics

    (from Recycling Today Magazine) Harnessing the power of magnetic currents has long been an effective way to separate and recover scrap metals. Now, researchers are looking at ways to use this same power to improve scrap plastic sorting methods. Scrap plastic comes in the form of production or processing scrap and from post-consumer streams. Production scrap can often be components or ...

  • What is zeta potential?

    Zeta potential is a measure of charges carried by particles suspended in a liquid (mostly water). Most particles suspended in water and wastewater, e.g. clays, silica, hydrated metal oxides, paper fibers, biological cells, etc., possess negative surface charges in the neutral pH range as shown in Fig. 1 (a simplified view of a particle in a suspension). The particle is said to carry a negative ...

  • Flexible welding fume extraction system in plant

    The challenge VAM Drilling (Vallourec Mannesmann Oil & Gas Nederland BV) is located in Heerhugowaard, the Netherlands. This facility has been around for over 40 years. Approximately 20 employees are turning/welding in the plant on a daily basis. Sometimes even 24 hours a day, if projects need to meet certain ...

  • Characteristics of Copper Wire Granulator

    Copper wire granulator is an advanced technology to deal with the waste copper wire and other various household wires, which have begun applied in 1980s by America and other industrialized countries. The dealing result is impressed by the advanced copper wire granulator. We can get pure copper granules and plastic from the waste copper wires after a ...

  • Recovering Valuable Chemicals from Air Emissions

    Air emissions in many cases are a waste of valuable natural resources that should have become useful chemicals. In some cases the economic payback from recycling/reuse of air emissions can be almost as much a motivation to control air pollution as government regulations. Examples of recycling and reuse of air emissions are sulfur oxides emissions that can be made into sulfuric acid, cement ...


  • Urban Air Quality Management

    ' Poor air quality due to pollution is a serious environmental problem in most urban areas. The greatest burden of pollution is on human health. Urban air quality management requires an integrated approach that (i) identifies the most serious problems and measures that offer cost-effective and feasible solutions across a range of economic sectors and pollution sources including industries, ...

  • Picking Their Membranes - Part I -

    Membrane use by water suppliers may not be new, but suppliers are considering membranes in new ways -- by number and variety of applications. Membranes can work on a wider range of resource waters, more efficiently and for less cost than before. Among membranes' attractions as substitutes for conventional water-treatment technologies, such as filtration, distillation and ion-exchange are: ...


  • Proposed boiler MACT sets aggressive emission limits

    On June 4, 2010, U.S. EPA proposed National Emission Standards for Hazardous Air Pollutants (NESHAP) for industrial, commercial, and institutional boilers and process heaters at both major and area sources of hazardous air pollutants (HAP) emissions.  EPA proposed separate rules for units at major sources of HAP emissions (greater than 10 tons per year [tpy] of any single HAP and/or greater ...

  • EPA finalizes boiler NESHAP

    EPA published the final National Emission Standards for Hazardous Air Pollutants (NESHAP) for industrial, commercial, and institutional boilers and process heaters at both major and area sources of hazardous air pollutants (HAP) emissions. EPA developed separate rules for units at major sources of HAP emissions (greater than 10 tons per year [tpy] of any single HAP and/or greater than 25 tpy of ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...
