National ENERGY GLOBE Award Oman 2018
To provide safety regarding environmental matters, AWAS International GmbH has developed and executed two vortex separators for collecting rain and floodwater from the apron at Salalah airport as well as two vortex separators serving the nearby Shell fuel farm. The main task of AWAS International GmbH in this project was to reduce a content of oil in water from 5000 mg/l to five mg/l so that this water could be discharged to the sea.
Annual rainfall of western Oman is 99 mm; it is received in an average of 66 days. Due to this factor, the waste water management system should be able to handle strong rainfall events and humidification in a short period of time. During the rainy season, waste water coming from airplanes and a fuel farm runoff the built-up area and subsequently contaminates water reserves nearby with oil and kerosene which is dangerous to the environment.
The solution is to separate the oil from the water to reduce contamination of water bodies. According to a statement of work, the separator discharges water from the airport territory into the sea with a maximal oil content of five mg/l. The system is constructed in a way that no oil is able to flow out of separator during heavy rainfall events.
AWAS International Separator system works without any filters, grids or fillers and it is backflow free. The separation of oil, sludge and water is a purely physical-mechanical process, without using any chemicals. These aspects reduce maintenance and operation costs and build a completely environmentally-friendly waste water treatment system.
