Abstract
A water treatment system includes an inlet line, a tank in fluid communication with the inlet line to receive therefrom a fluid flow comprising hydrocarbons and water. The tank includes components configured to separate the fluid flow into a hydrocarbon flow and a water flow, with the water flow including a residual amount of hydrocarbons. A first outlet line is in fluid communication with the tank to discharge therefrom the water flow. A second outlet line is in fluid communication with the tank to discharge therefrom the hydrocarbon flow. A sensor is associated with one of the inlet line, the first outlet line, and the second outlet line, and a valve is associated with the second outlet line. In addition, a controller is configured to determine a property of at least one of the fluid flow, the hydrocarbon flow, and the water flow using the sensor, and to control the valve based upon the property so as to reduce the residual amount of hydrocarbons in the water flow.
