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.

处理舱底水的方法有很多。然而，几乎所有这些方法都使用某种形式的重力分离和四次浮法来从水中去除油，这有一些局限性，例如：(i) 20微米或更小的油颗粒无法分离；（ii）舱底水中的各种含油废物会限制去除效率，特别是当存在非常致密和高粘性的油时，如燃油。电化学泡沫浮选是一种有效的浮选方法，但成本较高。油水生物修复在经济上是可行的，但由于需要较长的保存时间，在船上应用并不现实。目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价；（ii）开发一套实验室规模的处理系统，用于处理舱底水以去除水中的
