Abstract:
To solve such problems that separation/removal of oil contained in drain water is carefully considered, but a technique for separating/removing copper, which is regulated by a country, is not considered at all and remarkable generation of copper ions when compressed air or the drain water, which is generated when steam in the compressed air is condensed, passes through an instrument composed of copper components is also not considered at all.
An adsorption/removal tank 70, in which at least one of oil adsorption/removal layers 71w, 71y for adsorbing/removing oil and an adsorption/removal layer 71x for adsorbing/removing the copper ion are formed, is arranged in order to adsorb/remove both of the oil and copper ion contained in drain water.
