Patent DE-2406857-A1 (DE)
Title: Liquor removal from lagoon surfaces - using floating take off line with compensation for level changes
Inventor: WEILER WALTER
IPC: B01D21/24
Filed: 1974-02-13
Abstract: Liquor take off for open tanks esp. effluent lagoons consists of a line with a run off lip supported by a pair of floats on the water surface. The line is connected to the water run off a flexible joint pivoted at two points so that the line can rotate as an arm. The floats follow any variation in water level and the line rotates accordingly. The top pivot is so arranged that as the arm rotates anti-clockwise, the lip assumes a higher level with respect to the water surface. This is to compensate for the fact that as the angle of the arm reduces to nearer horizontal, it becomes filled with water and exerts a heavier pull on the floats. By raising the lip a constant run off rate is assured. For use on open settling tanks, esp. effluent lagoons, where sedimentation occurs and it is necessary to draw the liquor from the surface. Variations in level inevitably occur in such tanks and floating off takes are known. However, the lines tend to run full when at a shallow inclined angle and this makes them run lower at the surface, causing higher offtakes when the tank level is low. The device described avoids this.
