The HELI-SEP® is a single vertical cylindrical vessel design that utilizes fluid velocity reduction, differential specific gravity and coalescences to separate nonsoluble oil, solids and entrained air from oily water. Three different actions occur with in this one vessel to provide the efficient removal or reduction of oil content to 15 PPM or less at flow rates up to 44 gallon per minute. Oily water is pulled into the HELI-SEP® by the integral pump. The water flows through a permanent "honeycomb" matrix featuring a large amount of surface for the oil to make contact with and coalesce. As the droplet increase in size they detach from the surface of the matrix and float to the top of the vessel. The water is then pulled through an oleophillic media where fine oil droplet are captured and retained until the oil discharge cycle. When sufficient oil accumulates the unit enters into an oil discharge and backwash cycle. During this process the oil is flushed from the media and discharged from the unit.

The HELI-SEP® can be fitted with an oil content measuring device or bilge alarm to monitor the amount of oil in the discharge from the separator and initiate recirculation and prevent discharge when above regulation or set point. The HELI-SEP® meets the International Maritime Organization MEPC.60 (33) regulation relating to the discharge of bilge water from ships. The HELI-SEP® has been approved by the U.S. Coast guard and other governments and regulating agencies around the world. The bilge alarm is a proven and effective monitor and alarm system that monitors a sample stream of the water to be discharged; the water is exposed to light as it passes through a fixed cell. The presence of oil that is above the legal limit of 15 PPM places the unit into the alarm mode, notifying the operator and diverting the discharge flow into a recirculation loop until the oil content falls below the legal limit set point. The bilge alarm is furnished with recirculation and overboard or discharge valves and is pre-wired to simplify and reduce installation cost.
