GENERAL INFORMATION
The Westlake Environmental Oil Water Separator (OWS) is a most efficient tool for removing non-emulsified (free and dispersed) oils and grease from a wastewater stream that may also contain up to 300 ppm of solids. The coalescing media is configured to allow the oils to rise to the surface and cascade into an isolated oil chamber, while the solids settle into the sludge chamber to be isolated from the flow.
The model OWS will coalesce and concentrate 20 micron and larger free fats, oils and grease from water to produce a clean water effluent of 10 ppm or less free oil. The concentrated oil will have less than 5% water. The separators can be installed above, flush or below grade and can operate by gravity or pumped feed, depending on the application.
OPERATION
The wastewater enters the OWS influent chamber via a non-clog, energy dissipating baffle that distributes the flow across the width of the coalescing pack. The separation chamber has a Westlake Media Bundle that is filled with oleophilic media that insures collision of the oil droplets, which become larger and quickly float to the water surface. As the oil layer reaches a given height on the water surface, it decants into an integral oil reservoir. The bundle is also designed such that solids will separate and settle into the sludge collection chamber. Clean water flows under a baffle and over an adjustable 304 stainless steel weir into the effluent chamber. Liquid level in the separator is determined by the height of the adjustable weir. The clean water exits the effluent chamber through an outlet flange. Sectionalized, gasketed covers are provided to allow easy access to the separator internals.
