Abstract: A method for load management for an electric drive machine comprises receiving a fuel signal indicative of a volume of fuel provided to an engine associated with the electric drive machine, receiving an engine speed signal indicative of a rotational speed of an output shaft of the engine, and receiving a boost pressure signal indicative of a pressure of air at an intake manifold of the engine. The method further includes determining a torque adjustment factor based on the fuel signal and the boost pressure signal, and determining a torque capability of the engine based on the fuel signal and the engine speed signal An engine torque limit is determined based on the torque capability and the torque adjustment factor A first motor torque command signal is determined for a first electric drive motor of the electric drive machine based at least in part on the engine torque limit.

Abstract: A dissolved air flotation system and method for purifying fresh water. The system is self-contained within a standard shipping container, with all components disposed in-line within the shipping container. Float is removed from the flotation tank with a skimmer that drives float downstream onto a conveyor belt, and the conveyor belt conveys float away from the flotation tank, in the downstream direction, and deposits the float in a collection tank. Clean water may be drawn from the flotation tank continuously, while float may be removed periodically.
