  • Liquid extracting device and associated method
    Patent number: 5169527
    Abstract: Two porous belts and a plurality of rollers are provided for removing liquid from sludge. The sludge is positioned between the two belts and moved under compression over the rollers thereby causing the liquid to be discharged from the sludge and into a catch basin below. The rollers are relatively positioned to form an upwardly projected undulating contour thereby defining an area under each of substantially all rollers for the placement of liquid deflectors under each roller. An associated method provides steps for positioning sludge between two belts, moving the sludge in compression over rollers to remove liquid from the sludge and deflecting the extracted liquid from a portion of the belts.

  • Method and device for the generation of fine gas bubbles in a liquid
    Patent number: 5098581
    Abstract: In order to generate fine gas bubbles in a liquid, aeration elements (12) arranged in the bottom area of a basin (10) are applied with gas via a gas feeding conduit (14). The aeration elements are part of the gas feeding conduit. The weight of the aeration elements together with the gas feeding conduit is chosen in such a way, that special fixation elements for the gas feeding conduit are not necessary.
