An Oil-Water Separator also known as an Oil Interceptor is a gravity separation device designed using Stokes' law principles that define the rise velocity of oil droplets based on their density, size and water properties. The design of the separator is based on the specific gravity difference between the oil and the wastewater because that difference is much smaller than the specific gravity difference between the suspended solids and water. Based on that design criterion, most of the suspended solids will settle to the bottom of the separator as a sediment layer, the oil will rise to top of the separator, and the wastewater will be the middle layer between the oil on top and the solids on the bottom. The API Design Standards, when correctly applied, make adjustments to the geometry, design and size of the separator beyond simple Stokes Law principles.
The GCT Fabricators range of Oil-Water Separators, a high-performance gravity-displacement separator system designed to provide the highest efficiency attainable in an enhanced-gravity separator, exceeding both API (American Petroleum Institute) and SANS (South African) standards. At the heart of the oil-water separator is a patented system utilising a cross-flow design with a removable coalescer, offering the highest possible efficiency with the lowest practical maintenance. With our brand new Oil-Water Separators we at GCT guarantee efficiency. Our separators are available with three standard flow rates 1000 L/h, 2000 L/h & 4000 L/h but our design team are able to manufacture custom separators to cater for for applications with flow rates as high as 200 000 L/h.
GCT oil-water separators are Cross Flow Interceptors (CFI’s) and are made from high quality stainless steel making them resistant to any form of corrosion and stain. All GCT oil-water separators have been designed by industry professionals and are manufactured in our factory under careful supervision, after which each product is inspected for welding and assembly defects.
