S S Separation Process Separation Process ti ti P P The Crystal Sea oily The Crystal Sea oily- -water treatment units are designed to separate the liquid phases water treatment units are designed to separate the liquid phases in six stages located within a single vessel. Each stage is devised to remove oil particles in six stages located within a single vessel. Each stage is devised to remove oil particles of a certain size and renders the liquid cleaner for the next stage. This ensures greater of a certain size and renders the liquid cleaner for the next stage. This ensures greater effectiveness and manageable loads for each stage. Furthermore, it also precludes effectiveness and manageable loads for each stage. Furthermore, it also precludes undue contamination and clogging of various stages by oil, resulting in trouble free undue contamination and clogging of various stages by oil, resulting in trouble free- - operation. operation. Minute gas bubbles resulting from controlled vacuum conditions enhance the removal Minute gas bubbles resulting from controlled vacuum conditions enhance the removal of oil droplets from the water stream. Vacuum is created in the stages operating prior of oil droplets from the water stream. Vacuum is created in the stages operating prior to the circulation pump. Oil is retained at the upper portion of the stages and is to the circulation pump. Oil is retained at the upper portion of the stages and is gradually accumulated in collection zones. gradually accumulated in collection zones. Downstream from the pump the stages are slightly pressurized. Oil extracted in these Downstream from the pump the stages are slightly pressurized. Oil extracted in these stages is transferred continually into the collection zones through specially designed stages is transferred continually into the collection zones through specially designed conduits. The transfer of oil occurs due to the pressure differential existing between conduits. The transfer of oil occurs due to the pressure differential existing between the stages located upstream and downstream from the pump respectively. Continual the stages located upstream and downstream from the pump respectively. Continual oil extraction ensures outstanding cleanliness of the polishing stages and prevents oil extraction ensures outstanding cleanliness of the polishing stages and prevents accidental contamination of the effluent. accidental contamination of the effluent.
