Abstract: A method of treating a quantity of water that includes a first level of a contaminant and is discharged from a process includes mixing the water with an effluent having a second level of the contaminant to produce a condensate having a third level of contaminant, the second level being greater than the first level. The method further includes passing the condensate through a reverse osmosis system to produce a permeate having a fourth level of the contaminant and a concentrate having a fifth level of the contaminant that is greater than the fourth level. The method also includes oxidizing the concentrate in an electro-oxidation system to generate the effluent and directing the effluent to a point upstream of the reverse osmosis system to perform the mixing step.

Abstract: A roadside equipment (RSE) system that can be used for controlling traffic signals and other equipment and corresponding method. A method includes maintaining a traffic signal in a GREEN phase in a first direction, including displaying a GREEN indicator in the first direction. The method includes detecting an event indicating that the phase of the traffic signal in the first direction should be changed and changing the phase of the traffic signal to a pre-YELLOW phase in response to the detected event, including continuing to display the GREEN indicator in the first direction. The method includes wirelessly transmitting a message indicating the pre-YELLOW phase and a phase time, the phase time indicating a next change of phase of the traffic signal, and changing the phase of the traffic signal to a YELLOW phase when the phase time has been reached.
