Oil Content MonitorsBy NAG Marine
The history of Oily Water Separators (OWS) and Oil Content Monitors (OCM) on board commercial vessels is frustrating, confusing, and more often than not, very expensive.
The majority of commercial Oily Water Separator equipment is supplied with Oil Content Monitors that utilize light-scattering detection technology. These OCMs work by shining a laser light into an oily waste sample cell. As the light travels through the sample cell, it is reflected off of various molecules in the water so that its energy is attenuated.
