Company ProfileCase Study: Singapore Airlines—Changi Airport, Singapore
The Problem
As part of its new aircraft maintenance and repair facility at Changi Airport, Singapore Airlines faced a chemical disposal challenge. The facility used significant amounts of chemical dyes to identify stress cracks in airplanes and an array of solvents were used to clean engine parts during maintenance work.The EversTech Solution
EversTech engineers created a complete turnkey system to meet Singapore Airlines' needs. The system is based on EversTech's Catox Process, which uses chemical treatment followed by flotation and then oxidation of the recalcitrant organics by the use of ozone in conjunction with a catalyst. Please see the "Processes" section of this website for a more detailed description.
Singapore Airline's system was designed, assembled and fitted into a conventional freight container. The container was then shipped to Singapore in one piece and installed by our engineers.Environmental Benefit
The unit was completely self-contained and produced a disposable sludge from the flotation tank but, more significantly, an effluent with a COD less than 16 mg/litre from a raw effluent of over 2,000 mg/litre COD. The quality of the water was such that it could be continually recycled.
