Definitions

  • the invention relates to a sparger apparatus as defined in the preamble of independent claim 1.
  • a sparger is used to feed a first fluid such as gas into a second flowing liquid such as into a flowing liquid media. It is known in the prior art to use venture systems, and spargers comprising porous material such as ceramic, sintered or laser cut holing systems.
  • a known problem with spargers is the control of the bubble size of the first fluid that is fed into the second flowing fluid and to control the distribution of the bubbles of the first fluid in the second flowing fluid. Lack of control results in that tiny bubbles of first fluid merge together to create larger bubbles of first fluid or in that large bubbles of first fluid are divided to create smaller bubbles of first fluid that possible merge again.
