N2  - Shell CNS 'oil installation was utilized as a case study for its oily  waste problem. Investigations were carried out on the existing treatment  system believed to be ineffective. Sources and characteristics of waste~  water from oil tank farm and related oil product manufacturing were evalu-  ated. Treatability studies of discharges with very high oil concentrations  (mainly free oil and tempOrary emulsions) ranging from 70 to 2,240 mg/l  were conducted using two types of 6il separators, namely, oil interceptor  and compact plate separator (CPS).  Performance of the oil interceptor~ a very simple form of gravity  separator ·for oil-water mixtures,revealed a removal efficiency as high as  90% with effluent concentration of less than 15 mg/l oil and grease for a  properly designed and maintained unit.  Pilot-plant o~eration of the compact plate separator at the optimum  flow rate of 2.5 m /h demonstrated an oil removal efficiency of more than  90% even without external heating. -However, better effluents were observed  when it was coupled with an oil interceptor.serving as auxiliary unit.  Both treatment systems are inexpensive from the point of view of a  wealthy industry
