Treatment Process Overview• Unit Operations• Oil/water separation• Equalization basin (1-day, ~1 million gallons)• Dissolved air floatation• Cooling• Aerobic biotreatment• Settling (1-day, ~1 million gallons)• Media filtration and reverse osmosis• RO permeate to industrial reuse (boiler feed)• RO concentrate to permitted nearshore ocean outfall
Treatment Overview - Secondary Streams• Oil/water separator – oil to storage tank,settled solids to waste basin• DAF float and settled solids to waste basin• Settling basin solids, mucked out as neededand “landfarmed” prior to offsite disposal• RO prefilter waste stream to waste basin• Waste basin – can be returned to process,mucked out as needed
