Condensate is a by-product that is generated via the cooling/dehydration process of compressed air generation and treatment. Lubricated type air compressors pass a small amount of lubricant into the air stream. Atmospheric borne water vapor and lubricant combine to produce an oily water mixture that must be treated before disposal to sanitary sewer. Regardless of site conditions, it is virtually impossible to remain legally compliant with local discharge regulations without proper separation equipment.
