	HELI-SEP® PRINCIPLES OF OPERATION Oily water is drawn into the Separator by the system pump which is located on the discharge side of the Separator to prevent the formation of mechanical emulsion. The fluid enters the Separator near the bottom of the vessel, which is the solids sludge collecting chamber. Most of the oil separates from water immediately due to the difference in specific gravity and the reduced flow velocity inside the separator. The fluid flows upward through the separating media matrix while solids and sludge drop to the bottom of the vessel. This path maximizes contact with the separating media to enhance coalescence of the oil and increase solid/sludge fallout. The fluid exits the separating media where due to the difference in specific gravity the oil continues to flow to the top of vessel; the oil collection chamber. The water is then drawn downward through the polishing pack of polypropylene beads. The polishing pack coalesces any residual oil that may be left in the water, where when the droplets become large enough to break loose and rise to the oil collecting chamber. When sufficient oil has collected in the oil-collecting chamber the oil sensing probes create a signal to stop the system pump and open the clean water inlet valve. Pressurized water (sea water or fresh water) entering from the bottom of the Separator flows upward through the polishing pack and displaces the accumulated oil which is discharged through the oil discharge line. The upward flow of the clean water flushes out the polishing pack with each oil discharge cycle. After the oil has been removed and the oil sensing probes are again immersed in water, the Separator returns to the separating mode. The Separator vessel is equipped with two sample valves to extract an oil sample and determine the oil/water interface level. The manual valve located at the bottom of the vessel is provided for draining the vessel and for dumping the solids and sludge which have accumulated in the bottom of the vessel, the solids sludge collecting chamber. The Control Box contains a power switch which controls power to all internal circuits, an operation switch to select Flush or Run operation. Placing the Operation Switch in the FLUSH position will stop the system pump (if running), open the clean water inlet valve, flush the unit and discharge any accumulated oil. Placing the Operation Switch in the RUN position will activate the systemÕs pump for operation, and initiate the oil sensing probes to provide for the automatic discharge of accumulated oil and or air from the Separator. This is the NORMAL operating position. The Control Box also contains three indicator lights. The red light illuminates when the control power is on. The amber light illuminates when oil is being discharged from the system. The green light illuminates when water is being discharged from the system. A combination vacuum/pressure gauge mounted on the vessel indicates the vacuum or pressure inside the Separator's vessel. A pressure gauge mounted on the systemÕs pump outlet indicates the Separator's discharge pressure. HELI-SEP® with OCD flow diagram in PDF format HELI-SEP® WITH OCD PRINCIPLES OF OPERATION The oily water is drawn into the Separator by the system pump, which is located on the outlet of the Separator to prevent the formation of mechanical emulsion. As the fluid enters the Separator near the bottom of the vessel, which acts as the solids sludge collecting chamber, most of the oil separates from water immediately due to the difference in specific gravity and the reduced flow velocity inside the separator. The fluid flows upward through the separating media matrix while additional solids and sludge drop to the bottom of the vessel. This path maximizes contact with the separating media to enhance coalescence of the oil and increase solid/sludge fallout. The fluid exits the separating media where due to the difference in specific gravity the oil continues to flow to the oil-collecting chamber at the top of vessel. The water is then drawn downward through the polishing pack of polypropylene beads. The polishing pack coalesces any residual oil that may be left in the water, these droplet form larger droplets and when until large enough break loose and rise to the oil-collecting chamber. When sufficient oil has collected in the oil-collecting chamber the oil sensing probes create a signal to stop the system pump and open the clean water inlet valve. Pressurized water (sea water or fresh water) entering from the bottom of the Separator flows upward through the polishing pack and displaces the accumulated oil which is discharged through the oil discharge line. The upward flow of the clean water flushes out the polishing pack with each oil discharge cycle. After the oil has been removed and the oil sensing probes are again immersed in water, the Separator returns to the separating mode. A slipstream of the processed water discharge is fed through the OCD to continuously monitor the oil content in parts per million (PPM). The OCD then controls the processed water discharge per its oil content; if less than 15 PPM, the processed water is allowed to discharge normally; if greater than 15 PPM, the process water is diverted for recirculation and reprocessing. The Separator vessel is equipped with two sample valves to extract an oil sample and determine the oil/water interface level. The manual valve located at the bottom of the vessel is provided for draining the vessel and for periodic dumping of the solids and sludge that have accumulated in the bottom of the vessel, the solids sludge collecting chamber. The Control Box contains a power switch which controls power to all internal circuits, an operation switch to select Flush or Run operation. Placing the Operation Switch in the FLUSH position will stop the system pump (if running), open the clean water inlet valve, flush the unit and discharge any accumulated oil.

The amber light illuminates when oil is being discharged from the system. The green light illuminates when water is being discharged from the system. A combination vacuum/pressure gauge mounted on the vessel indicates the vacuum or pressure inside the Separator's vessel. A pressure gauge mounted on the systemÕs pump outlet indicates the Separator's discharge pressure. Standard flow rates for the HELI-SEP® system are between 0.5 and 10 M3/HR (2.2 and 44 US GPM), however larger and custom systems are available upon request.
