Operation
The separator shall be a special purpose prefabricated parallel corrugated plate gravity displacement type oil/water separator designed to remove free and dispersed non-emulsified oil and settlable solids, in accordance with API 421. The separator shall be comprised of a tank containing:
Inlet Compartment
The inlet chamber will be comprised of a non-clog diffuser pipe to distribute the flow across the width of the separator chamber. The inlet compartment shall be of sufficient volume to effectively reduce influent suspended solids, dissipate energy and begin separation. A sludge hopper will be provided to prevent settlable solids and sediment from entering the separation chamber.Separation Chamber
The separation chamber will contain parallel corrugated plates for enhanced oil/water separation. The plates will be spaced for optimum removal of free oil and settleable solids, and the corrugations will have a 45 to 60 degree angle with respect to the horizontal. Flow through the plate pack will be in a cross-flow configuration. This allows the oil to collect and coalesce in the high points of the corrugations while the solids collect at the low points. This also allows oil to rise without interfering with the falling solids, reducing the possibility of clogging. Plates shall be enclosed in a stainless steel frame to facilitate installation and removal.Sludge Hopper
The sludge hopper will be located prior to the separation chamber and will provide an adequate volume and baffling for the settling of any solids.Oil Collection
The oil will be collected at the end of the separation chamber by a fixed weir trough or rotatable skimmer. Either collection method will provide automatic decant of the separated oil through gravity outlet(s) on the side(s) of the separator. The type of oil collector depends upon the application.Integral Oil Storage Compartment
An integral oil storage compartment can be provided for storing separated oil. The compartment adjacent to the coalescing compartment would collect and store the oil discharged from the oil collector.Clean Water Chamber
The water will pass under the oil retention baffle and over the adjustable effluent weir, which maintains the liquid level throughout the separator, and exit through the outlet provided at the end of the separator.Covers
The separator is provided with a vapor tight cover that can easily be removed for service and maintenance.
