Method And Apparatus For The Sonic Measurement Of Sludge And Clarity Conditions During The Treatment Of Waste Water

View page
US Patent:
60620706, May 16, 2000
Filed:
Oct 29, 1996
Appl. No.:
8/741408
Inventors:
Frederick L. Maltby - Jenkintown PA
Yang Wang - Bensalem PA
Norman Nardelli - Morristown NJ
L. Jonathan Kramer - Warminster PA
Assignee:
Drexelbrook Controls, Inc. - Horsham PA
International Classification:
G01N 2902
G01S 1514
US Classification:
73 6149
Abstract:
A sludge blanket level is determined in a waste water treatment clarifier using sonic pulse reflections. Additionally, using similar techniques, the clarity of the waste water is determined. A sonic pulse is directed into the waste water. Echos are generated as the pulse encounters the impedance mismatches indicative of changes in the density of the water. The echos are compensated for attenuation as a function of travel time through the water, energy lost due to prior peak reflections, and are processed to remove random signals using correlation techniques. A sludge blanket is selected from the compensated echo signal as a function of the size and location of echo peaks. Additionally, the clarity is determined as a flnction of the area under the echo signal between two points corresponding to predefined levels in the clarifier tank.
