  • 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 ...

  • Milling filter cakes - Cutting instead of pressing to achieve more uniform particle size

    There are various methods of separating solids from a suspension. These include filtration, centrifuging and drying. In most cases, further processing of the resulting products cannot be carried out directly. They have to be reduced to the right particle size by means of a mill. This can be done with a Gericke Nibbler, which shreds the filter cakes efficiently using a basket and screen assembly. ...
