Design requirements for the treatment of stormwater contaminated with jet fuel oil using corrugated plate interceptor

Abstract

Oil contamination in the stormwater has been generally overlooked even though it causes major environmental pollution and a substantial threat to all species in the ecosystem. Likewise, the treatment of oil-contaminated stormwater in public areas and general industries, especially airports, has also been ignored. Airports are known as one of the most potent contributors to the jet fuel oil contamination of stormwater that pollutes the local waterways. There are many Best Management Practices (BMPs) of stormwater at airports, such as detention ponds, retention ponds, and infiltration basins in which stored water is exfiltrated through permeable soils. However, not many kinds of literature regarding specific actions taken to treat the stormwater contaminated with jet fuel oil within the boundaries of airport facilities. This paper presents the design requirements for the treatment of stormwater in an airport using corrugated plate interceptor (CPI). Specifically, this paper discusses the characteristics and the contaminants of stormwater runoff from certain airports and the design requirements of CPI in treating the wastewater. The design requirements were based on an actual study conducted in an airport using the CPI. The requirements include determining jet fuel concentration at the inlet and outlet of the CPI; selecting the jet fuel density; evaluating the flow rate, oil storage and sludge storage capacity; and determining the oil globule size and surface charge. In addition, the evaluation of the coefficient of surface separation and the design of corrugated plate packs are also elaborated.
