Abstract: An apparatus for stability testing of a wheeled assembly includes a straight fulcrum fixed relative to a horizontal surface. The straight fulcrum includes a straight edge parallel to the horizontal surface and located a first height above the horizontal surface. A first position mechanism includes a first position angle. The first position mechanism and straight edge define the first position angle as an obtuse angle and define a test area. A force mechanism vertically offset from the straight edge. The force mechanism applies a force to the wheeled assembly so when the wheeled assembly is positioned in a first position with one side of the wheeled assembly parallel to the first position angle, the force mechanism pulls the wheeled assembly in a direction toward a second position and the wheeled assembly rotates on a vertical axis. The second position includes a portion of the wheeled assembly contacting the straight edge.

Abstract: A method and apparatus for dewatering of effluents through the use of automated optimization using feedback control. The method and apparatus for feedback control optimizes dewatering processes for any water cleansing process that uses retention and/or flocculation aids (e.g., polymers) to impact endpoint water clarity. Disclosed implementations include processing using dissolved air flotation (DAF) and sludge cake formation. The methodology includes real-time monitoring of turbidity and incremental control of polymer to manage changes to turbidity/suspended solids due to operating parameters such as temperature, chemical variations, and mechanical influences.
