An upgraded HV only washbay required a compliant water treatment plant for water recycling. Monitoring equipment and incorporated programming was necessary for the overall integration of each facility supplying and drawing from the Water Treatment Plant.

The optimized process consists mainly of three stages (solids settling, oil separation and water polishing), each designed to achieve a specific goal.

Water quality monitoring is a high priority with environmental staff onsite constantly testing the treated water. An Oil Content Meter (OCM) was a part of the HV Water Treatment Plant to monitor the discharge water. The OCM continuously samples water after the final MyCelx polishing stages, it is certified by Lloyds register. The approved oil content monitor is coupled with the control system such that only treated water with less than 10 ppm is discharged from the system to the clean water holding tank.
