The use of lubricated compressors results in the presence of oil in the condensates, the water law then prohibits its discharge without prior treatment.
The decanters are defined according to the flow of air produced by the compressed air plant, this flow rate according to the ambient humidity will result in a quantity of condensate that will be sent to the decanter for treatment. The treated water will then be directed to a waste water network and the oil will be recovered in a separate container.
