An Introduction to Oily Wastewater Collection and Treatment

Oils and oily sludges obtained from treatment or pretreatment systems may be disposed of by several methods. These are reuse/recovery, incineration, selling, waste hauler, landfill, and land disposal. Final disposal options must be evaluated concurrently with oil-water separation methods and environmental requirements to establish the most cost-
