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.

有许多解决方案可以处理舱底水。然而，几乎所有这些设备都使用某种形式的重力分离和四次浮选来去除水中的油类，这些方法具有局限性，例如(I)20微米或更小的油类颗粒无法分离，以及(Ii)舱底水中的各种含油废物会限制去除效率，特别是当存在非常稠密和高粘度的油类(如燃料油)时。电化学法浮选泡沫是有效的，但成本很高。生物修复含油污水在经济上是可行的，但由于需要很长的停留时间，在船上应用是不现实的。目前研究工作的目标是：(1)对所有现有的舱底水处理技术进行经济评估；(2)开发实验室规模的舱底水处理机组，用于处理舱底水，以清除 以及回收石油。
