RAF Brize Norton is located about 30 minutes from Oxford, UK. It is the largest RAF base in the world, with around 6,000 staff and Service Personnel over 1,190 acres! The RAF’s Air Mobility Force (Air Transport) and Air-to-Air Refuelling forces, utilising aircraft such as the Airbus Voyager, Atlas C.1 A400M and Boeing C-17A Globemaster.
Large airport runways often utilise by-pass oil separators due to the very large catchment are that is being covered. On this site, 3no. SPEL Stormceptor’s were utilised to cover the main runways and taxiways as large spill risks are unlikely and therefore treating the ‘first flush’ or first 10% flow and allowing the storm flow to bypass is often acceptable. However for areas with a higher spill risk, such as in refuelling locations, or bowser parking areas, full retention separators are often used.
In this case a SPEL Puraceptor P050/1CSC which has a spill capacity of around 17,000 litres and a SPEL Puraceptor FP1C/SC forecourt separator was also supplied which has a spill capacity of 7,600, which is the capacity of a complete section of a standard fuel tanker, however on some MOD bases, large fuel tankers are used and therefore larger spill capacity is required, such as from a P050/1CSC.
