Dynasieve: A Powerful Tool for Environmental & Water Treatment

Dynasieve is a term widely used in environmental and water treatment to refer to a specific type of filtration technology known as self-cleaning rotary fine screens. These screens play a crucial role in separating solids from liquids, ensuring efficient and reliable treatment processes. Among the leading providers of Dynasieve technology is *Andritz-Ruthner, Inc. *, a company renowned for its innovative and high-performance solutions.

Understanding Dynasieve Technology

Dynasieve systems employ a rotating, perforated drum or cylinder to filter out suspended solids from liquids. The key features that differentiate Dynasieve from traditional screens are:

  • Self-cleaning mechanism: The screen constantly rotates, and a built-in cleaning system removes the accumulated solids, ensuring continuous operation and preventing clogging.
  • Fine filtration: Dynasieve screens can achieve very fine filtration levels, ranging from a few micrometers to several millimeters, depending on the application.
  • High flow rates: Due to their continuous operation and efficient cleaning mechanism, Dynasieve screens can handle large volumes of liquid.
