Oil Water Separators for Ships Principle of Operation
'Supersep' Oily Water Separator use latest coalescence principle. Generally these separators are two stage separators. The stages are named Primary and Secondary. The primary separating stage uses conical disc stacks or parallel plates for removing coarse Oil globules. The secondary separating stage employs coalescing cartridges for removing very fine Oil globules. Before operation, the complete system is primed with clean water. The pump for the separator sucks oily water from the oily water storage tank and discharges it into the primary stage. This stage provides large surface area for oily water to flow over and thus helps in coalescing finer Oil globules. Water with traces of Oil is then passed to the secondary stage, where it is made to pass through the coalescing filters. These filters retain the dispersed Oil phase and when it gets saturated with Oil, large Oil globules are released, which can easily separate. The separated Oil gets accumulated in the top portion of both columns and is sensed by level control probes fitted thereon. These probes actuate corresponding electro-pneumatic/electromagnetic valves and drain out the accumulated Oil, from the separator. These separators can handle oily water mixtures containing up to 30% Oil and can work automatically.
