  • Installation of Radar Level Instruments in Anaerobic Digesters

    ABSTRACTThere are numerous well-proven options available for level determination instrumentation. Instrumenting treatment processes present some unique challenges. Some of these include the ability for wastewater or residuals to clog and blind instruments. Level determination in an anaerobic digester presents these problems as well as others including foaming, surface agitation, and operation in ...

  • What are the parameters of an extended-aeration activated-sludge system?

    The activated sludge process is the most widely used biological water and wastewater treatment. As is well known, by its means, suspended-growth microorganisms are applied to breakdown wastes. Aeration, the mixing of air and a liquid, is the means used to speed the reactions involved. Aeration methods include spraying the liquid into the air; diffusing air into the liquid or agitating the liquid ...

  • Processing Wastewater Sludge Using Dewatering Containers

    The relative cost of dewatering equipment varies widely and is directly related to the processing rate. For smaller utilities that need to dewater sludge in batches, dewatering containers are an alternative that can be relatively inexpensive and simple when compared to other technologies on the market. The most common type of dewatering container is based on a roll-off box design, although any ...

  • Green Green Grass

    A few years ago the North Sea managed a twelve month period without any major shipping disasters. Good news for the environment you’d have thought. However, in the same period up to one hundred thousand tonnes of oil were estimated to have been released into the sea. Some of this can be put down to natural occurrence, but by far the major part is dispersed from aircraft and shipping fleets ...


  • Mixed MSW composting is steady as she goes

    Two new facilities came on line in 2006, while one ceased operation and a second is shifting to a new technology. Annual survey identifies a total of 14 plants. Part I STEADY-STATE may be the best phrase to describe the status of facilities composting mixed municipal solid waste in the United States. In fact, steady-state may be the best phrase to describe solid waste composting in general since ...

  • A Citizen`s Guide to Bioremediation

    What is bioremediation? Bioremediation is a treatment process that uses naturally occurring microorganisms (yeast, fungi, or bacteria) to break down, or degrade, hazardous substances into less toxic or nontoxic substances. Microorganisms, just like humans, eat and digest organic substances for nutrients and energy. In chemical terms, 'organic' compounds are those that contain carbon and hydrogen ...

  • 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 ...
