  • TOC analysis at airports

    As other industrial devices airports have to control their run-off weter for TOC and/or COD. The amount of waste water produced at airports is not negligible: The Frankfurt airport (one of the biggest airports in Europe) has produced 1.63 million cubic meters in 2006, the same amount as a medium-sized city. The sewer system of this airport consists of a 200km tubing system with a low quantity of ...

  • Treatment performance and microbial characteristics in two-stage membrane bioreactor applied to partially stabilized leachate

    A two-stage membrane bioreactor system was applied to the treatment of partially stabilized leachate from solid waste landfill in Thailand. In the system, an anoxic tank with incline tube for biomass separation from re-circulated sludge is followed by a second-stage aerobic tank in which a direct submerged hollow-fiber membrane module is used for solid–liquid separation. During steady operation ...

  • Pulse shear stress for anaerobic membrane bioreactor fouling control

    Increase of shear stress at membrane surfaces is a generally applied strategy to minimize membrane fouling. It has been reported that a two-phase flow, better known as slug flow, is an effective way to increase shear stress. Hence, slug flow was introduced into an anaerobic membrane bioreactor for membrane fouling control. Anaerobic suspended sludge was cultured in an anaerobic membrane ...

  • Wastewater treatment down-time `not acceptable`

    Reliable 24/7 monitoring and control of a pharmaceutical company's wastewater facility is fundamentally important to the successful operation of the entire business. This is because failures or down-time in the wastewater treatment process would quickly result in waste stream back up. It follows therefore that monitoring equipment should be extremely reliable and this is why Shasun Pharma ...


  • Buy Smarter – what questions should you ask when buying a Spectrophotometer?

    Spectrophotometers are relied on by a wide range of laboratories, for tests ranging from specific parameters, like chlorine or metals concentrations, right through to complex analyses of reaction kinetics. When choosing a spectrophotometer the range of specifications and price is vast, so take the time to list the features you need before you buy and make sure you choose the right one. ...

  • Mixed MSW composting in transition

    WITHOUT a doubt, composting the mixed municipal solid waste stream is a “niche” business. It is an MSW management option that seems to be viable in very specific situations. In some instances, these plants were built to service tourist destinations, often in somewhat rural areas where recycling is difficult and landfills are distant. In several other cases, public agencies built plants to extend ...
