Abstract
Coastal water is liable to recurrent oil spills from land based oil production, industrial and power generation sites. Technologies for source control are always preferable from the financial and environmental standpoints. However, accidental release of oily wastes mandates immediate interventions via state-of-the art technologies. An integrated set of source and accidental oily waste management is recommended in almost all coastal zones with priority dedicated to those locations nearby touristic sites such as Red Sea and Mediterranean Sea. This paper sets practical criteria for identification, selection and prioritization of oily waste water management via source control and/or accidental release. Identification schemes include; mechanical/physical separation, dissolved air floatation, advanced membrane separation and chemical interventions. The latter scheme capitalizes on the latest advances in flocculation and dispersing technologies. Moreover, financial indicators including capital, operating and unit costs have been developed for
