Maritime Sector Water Treatment
Treating maritime sector water, like bilge water, is vital for protecting marine ecosystems and complying with strict environmental regulations. Mestraco offers a compact solution that efficiently removes oil, chemicals, and other pollutants from bilge water, preventing ocean contamination and supporting sustainable maritime operations. This not only safeguards aquatic life but also helps shipping companies meet regulatory standards and avoid penalties.

The Bilge Water Challenge in the Maritime Sector
Bilge water management remains a critical environmental and operational challenge within the maritime industry. As ships operate, bilge water accumulates in the lowest part of the vessel, combining oil, grease, chemicals, and other pollutants. Regulatory bodies worldwide mandate that this water be treated before being discharged to prevent marine pollution. Typically, a ship can generate between 100 to 1,000 liters of bilge water daily depending on its size and operational intensity.
This accumulation presents significant risks not just to marine life but also to the broader ecological systems. Oils and other chemicals in untreated bilge water can have devastating effects on water quality, marine habitats, and biodiversity.
The Power of Efficient Bilge Water Treatment
The adoption of effective bilge water treatment solutions is essential for compliance with international maritime pollution standards (like MARPOL Annex I). Implementing advanced water treatment systems allows vessels to dramatically improve their management of bilge water, ensuring that it is processed efficiently and released safely back into the ocean with minimal environmental impact.
Modern treatment systems, particularly those that avoid traditional filters, can offer faster processing and reduced maintenance. By eliminating the need for filter replacements, these systems are not only cost-effective but also avoid the downtime associated with filter maintenance.

Mestraco Superclean: A Solution for Maritime Water Treatment Use
The Mestraco Superclean process is a state-of-the-art solution for bilge water treatment, known for its speed, efficiency, and simplicity. This technology operates without the need for filters, leveraging advanced separation techniques to efficiently remove oil and solids from bilge water. Capable of achieving oil content as low as 5 parts per million—well below the generally required standards of 15 parts per million—it offers an exceptionally clean and efficient operation.
Designed to be both compact and effective, Mestraco Superclean is perfectly suited for integration into maritime operations, where space and efficiency are at a premium. By utilizing this innovative technology, vessels can enhance their environmental performance, reduce the risk of pollution fines, and contribute positively to the health of global marine environments.
Graywater
Large amounts of graywater are generated onboard ships. While less polluting than blackwater, it still contains fats, chemicals, soaps, and particles that must be treated before discharge. We see the reuse of graywater onboard as an interesting area. So-called technical water can be used for various purposes onboard a ship.
