    Hazardous waste treatment solutions for site remediation

    The contamination of soils as a result of prior chemical production can often be unpredictable and diverse. The majority of such pollutants will require an ex-situ treatment method. Many of our VacuDry units can be used for direct-feeding contaminated soils. To reduce the input amount for thermal treatment, the VacuDry units can also be used in combination with soil-washing plants: In this case, customers only feed the high polluted fractions and screened fines (e.g. below 10 mm), as well as the filter-cake from the soil washing process. However, we are able to handle soil contaminated with mercury, hydrocarbons, PAH, PCB, dioxins, furans, organic-lead compounds and many more. VacuDry plants for on-site ex-situ remediation projects are delivered in a modular design.

  • VFD in wire and cable industry

    In the wire and cable industry, many processes begin with pay-off and end with take-up wire. In the part of pay-off wire, how to control the uneven tension is the urgent difficulty for many equipment design engineers and products control engineers. In the past electric design, the engineers used to adopt the A/D, D/A module of PLC, using PCB with tension control technique, and gain the pay-off speed by read the potential of potentiometer with tension swing bar. In this method to maintain a constant tension, it usually adopts the signal line from potentiometer with the tension swing bar and analog signal line from the D/A module which control the speed of the variable frequency drive (VFD).

  • Dustless Lead Paint Removal & Nuclear Decon Tools for Concrete Scabbling

    When concrete is contaminated with PCBs, radiation or other hazards, scabbling is often the only means of remediation. By removing a thin outer layer from a concrete surface, our shrouded power tools can make a structure safer for occupancy or demolition. Our powerful VAC-PAC® HEPA vacuum captures all dust, debris, and air-borne contaminants for easy transportation and disposal in standard 55-gallon (200L) drums. Whether you’re applying a new coating system or  a concrete overlay, a Concrete Surface Profile number (CSP 1-9) is often specified according to ICRI’s Technical Guideline No 310.2R. The examples below illustrate how Pentek tools can achieve your requirements:

  • Soldering Fume Extraction

    Soldering fumes are Unbreathable. Soldering enables the joining of metal parts by melting a filler metal to attach wires and other metallic components. The fumes generated from melting solder especially solder containing Lead or Tin present are dangerous and require local ventilation to remove harmful smoke from the work area. Soldering application need to be properly ventilated to prevent toxic fumes from reaching the worker`s breathing zone. There are a number of different industries such as the electronics assembly industry and electronics repair comapnies who must deal with the hazards of solder smoke. Fumes created by automated PCB soldering including wave soldering machines, handheld soldering irons, torch brazing and furnance brazing are often ignored because of the small volume of smoke generated. However, these applications still require careful consideration as dangerous fumes can impair employee’s respiratory tracts depending on the filler metals used. Because manual soldering applications require working with tiny components, workers end up positioning their heads right above toxic rosin or lead solder fumes with a direct exposure into their throat, nasal passages and lungs, and as a result, they can experience respiratory complications. Rosin irritation can cause various side effects and the inhalation of lead fumes is carcinogenic. As lead oxide smoke collects in your lungs, it can be transferred into your bloodstream. Diversitech recommends installing soldering fume extraction equipment to prevent the inhalation of dangerous fumes. These ventilation units will not only protect each person working at a soldering station when installed and positioned correctly, but they will also prevent fumes from contaminating other worker’s lungs.?

  • Airport Environmental Monitoring

    Water pollution from airport run-off is increasingly coming under public and government scrutiny. As environmental regulations tighten, the ability to monitor for aviation fuel contamination from runway run-off has become essential.

    Monitoring sites at airports can be extremely challenging often with no power or telephone lines available and with limited access for maintenance. Chelsea’s robust UviLux Hydrocarbon Sensor with its low power consumption and high accuracy is ideally suited for this application. Installed at various locations around the airport, deployed with it’s own integrated anti-biofouling system, utilising the GSM network, the monitoring sites send data to a secure ftp site, where any internet enabled device can access the data. In this way the systems act as any early warning system allowing any hydrocarbon discharge to be detected in real-time.

    Optional environmental monitoring features include remote control to allow the user to turn equipment on and off, change the sample rate and detection range. There is also a facility to allow SMS text and email alarm notifications triggered by user-defined set-points together with customised web pages, data displays and automated data downloads via an ftp server.

    Airport runoff can contain high concentrations of various pollutants, in particular polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), the environmental levels of which have to be monitored. An understanding of the magnitude of contamination due to airport runoff water is important for the effective management of airport infrastructure. Chelsea’s robust UviLux Hydrocarbon Sensor with its low power consumption and high accuracy is ideally suited to the airport environment.
