b'LT ENGINEERINGCATALOGSYSTEM COMPONENTSThe ParkUSA Elevator Oil-Water Interceptor is available effluent discharges to the sanitary sewer via a sample well. with the following components: Depending on the application, the oil-water interceptor may be installed below the elevator pit floor, at pit floor level,Steel Separator: The Separator is located freestandingor at a remote location. The interceptor is constructed of (Model ES) on the floor near the shaft, floor or wallsteel, fiberglass, or precast concrete providing years of mounted (Model EX) or can be located outdoors continuous service. The interceptor is divided into several (Model EC) & buried below grade. The separator is ratedcompartments where elevator discharge oil will coalescefrom 50 to 400 gpm depending on the quantity ofand reside on the surface.elevator shafts to be served.The process taking place starts when the oil-water mixture High Oil Alarm Panel (intrinsic safe): Indicates enters the separator through the inlet elbow into the High Oil Level of the separator, in the event of a pre-separation chamber, proceeds through the plate high accumulation of oil. The panel has a Separator inlet chamber, and makes a 180 degree turn to enter the High Level light & horn, a Silence button, and ancoalescing plate pack. The oil in this mixture is usually in auxiliary contact for a BAS System. the form of droplets of various sizes. As the oil water mixtureWastewater Systemsflows through the plates, the oil droplets tend to rise in Pump Control Panel (intrinsic safe): The Control Systemthe water due to the buoyancy effect. As the droplets rise, consists of float sensors and a unified control panelthey come in contact with the underside of the plates and (NEMA 4X weatherproof) that is wall mounted near coalesce, forming a thin film of oil on the underside of the the elevator shaft. plates. This film flows upward along the plate surface until it reaches the plate peaks. There it accumulates in a thicker oil Elevator Sump Pump (explosion proof): Submersiblelayer.
