There are many solutions exist for treating bilge water. However, almost all of them use some form of gravity separation and forth floatation for removal of oil from water, which have limitations such as (i) oil particles that are twenty micrometers or smaller cannot get separated and (ii) variety of oily wastes in bilge water can limit removal efficiency, especially when very dense and highly viscous oils such as bunker oil are present. Electrochemical methods for froth flotation are effective but expensive. Bioremediation of oily-water is economically viable, but an on-board application is impractical due to requirement of large holding time. The objectives of the current research work are: (i) economic evaluation of all the existing bilge water treatment technologies and (ii) develop a laboratory scale treatment train for treatment of bilge water for removal of the contaminants as well as recover the oil.

有许多处理舱底水的解决方案。然而，几乎所有这些方法都使用某种形式的重力分离和浮选来从水中去除油，其具有局限性，例如（i）二十微米或更小的油颗粒无法分离，（ii）各种含油废物舱底水会限制去除效率，特别是当存在非常稠密和高粘度的油（例如船用油）时。泡沫浮选的电化学方法有效但昂贵。含油水的生物修复在经济上是可行的，但由于需要较长的保持时间，在船上应用是不切实际的。当前研究工作的目标是：（i）对所有现有舱底水处理技术进行经济评估，以及（ii）开发实验室规模的舱底水处理系统，以去除舱底水 污染物以及回收油。
