Environmentally and cost friendly: GEA equipment for treating bilge water

To protect the sensitive ecosystem of the world's oceans, bilge water must be de-oiled to a legally specified level before it is discharged into the sea. The innovative system solutions from GEA used to treat bilge water not only accurately meet the strictest specifications during this process but also offer operators enormous economic advantages.

In accordance with the guidelines of the International Maritime Organization (IMO), the residual oil content in the water that is pumped out must not exceed a limit of 15 ppm, or 5 ppm in some regions. Our treatment systems are designed accordingly to ensure that the required values are achieved safely and sustainably. During this process, the treatment plant separator continuously separates the oil and water phase, while also automatically removing sludge from the bilge water. This treatment process is used to reliably reduce the residual oil content to below the legally required level of 15 ppm. Auxiliary equipment can be used to even achieve maximum values of 5 ppm.

Oil monitor to ensure adherence to legally prescribed limits

We use a special oil-in-water measuring device to monitor the aqueous phase and ensure the purity levels of the de-oiled water. If the required levels of residual oil in the water are exceeded, the liquid is recirculated to the bilge water tank and is only released when it meets the exact environmental requirements.

Advantages of using GEA high-performance separators

The GEA plants for treating bilge water, with a high-performance separator as the main component, offer a range of advantages that systematically focus on the requirements of the oil and gas industry. Not only the significantly reduced disposal costs resulting from this process, but also the low energy consumption and space-saving construction of our separators reduce the operating cost for operators sustainably. The recovered oil can be used by operators for different purposes, thus providing additional cost efficiency.

GEA separators process large volume flow rates at the highest level of separation accuracy - even movements of the ship do not affect the separation efficiency. The system is also designed to be self-cleaning and operates continuously, even if the composition of the bilge water changes, thus ensuring that it is perfectly suitable for unsupervised operation. We not only use corrosion-resistant duplex material for our plants, but can also provide them in an explosion-protected design in accordance with IECEx, if required.
