Produced water discharge throughout the world is regulated to ensure that minimal oil enters our oceans and waterways. Effluent water from production separators typically contains 100 – 800ppm oil, depending on the effectiveness of the separator, demulsifier and residence time of the system. Some operators set their own standard to 10 ppm. It is therefore necessary to ensure that the oil in water emulsion, which remains after crude oil and water separation, is resolved prior to overboard discharge. In addition, if produced water is to be re-injected into the reservoir it is important that any solids present are removed in this water treatment stage.
