This two-stage unit filters the fuel as FTS or the oil as OTS before the water separation in the coalesce elements, which increases the performance and service life of the equipment in case of contamination with larger solid particles


Every yacht, every container-, freight- or passenger ship has complex technology that has to work properly despite numerous external influences. For protection of different drives, hydraulic equipment and systems from contamination or corrosion over time, We offers a wide-ranging portfolio of filter and separation solutions for any application area both on and below deck. All products can be flexibly adapted to the structural conditions of any type of ship and reliably clean all of the fluids that keep ships running, and productive. It goes without saying that filtration and separation standards comply with international standards

Hydraulic & SMO Oil

2 and 3 stage complex technology is built into every asset, which must function perfectly even in wind and weather.

To protect the various hydraulic systems on and below deck from contamination and corrosion, we offers a broad portfolio of filter and separation solutions, including filter elements – original parts or replacement elements that are compatible with other filter systems.

They reliably clean all liquids to keep the ship running and thus its profitability.

All filtration and separation solutions meet international standards and are approved by leading marine companies.


Bilge, Slop, Rainwater & Salvage

De Oiling

The system is intended for separating oil / Water out of oil-water mixtures, bilge and slop water. Solids are also separated. The system is certified in accordance with IMO resolution MEPC.107(49).
The PPT-BWS/MESB-VT is a compact built, two- stage separator with continuous, reliable operation. With application down to under 1 ppm.

De Watering

The treatment of oil and fuels is based on the coalescer process. When the contaminated water swirls, larger drops of water form on the filter surface and sink down into a tank. If a smaller residual water content results, an additional separation system is positioned downstream of the coalescer elements. Here the oil or the fuel flows through a water-resistant membrane, which itself retains very fine water droplets. In this way the residual water content can be reduced down to 70 ppm. The coalescer process makes the use of centrigues or chemical additives unnecessary.

Before it can be drained into the ocean, the water that collects in the bilge in the hull of the ship must be cleaned. Bilge water separators from Filtration Group separate water, oils and solids in the first cleaning phase. The separation of tiny droplets of oil after coalescence reduces the residual oil content to internationally standard values of under 5 ppm. This meets the requirements in National Special Areas and Particularly Sensitive Sea Areas, as well as the “Green Ship” and “Green Harbour” limit values.

These units are designed to produce between 1.5 to 30 m3/day
of fresh water to be used on- board. This water is monitored by the salinity control system.

• Water monitored by salinity control system
• Automatic dumping when water contains more
than 4 ppm of salt
• Produce between 1.5 to 30 m3/day of fresh water


Especially on the high seas, far from safe, land-based drinking water supplies, extracting fresh drinking water

from seawater is critically important. We offer high-performance water makers and reverse osmosis systems for seawater

desalination, as well as automatic filters and membrane filters for drinking water treatment.

Our standard products can be used with filter ratings betwe0.02 and 5,000 μm, for maximum voluen me flow rates of up to 5,000 m3/h. In addition, we develop customized solutions for specific requirements.

Potabilizers are designed to meet the need on board
ship to treat the water produced by evaporators, producing

suitable drinking water.
• Produces sterilized, suitable drinking water • Re-hardening process
• Sterilization carried out using UV radiation • Salinity: between 0.5 and 4 ppm of NaCl


OPS system that treats ballast water flow rates of up to 800 m3/h with proven technology in accordance to the applicable IMO D2 standard. The OPS comprises:

– A maintenance free pre-filtration system
– An automatically back flushable main filtration system
– A low-pressure UV irradiation facility for disinfection
Even the more stringent requirements applicable in the USA (USCG standards) can be fulfilled as the values obtained in both the land and sea tests fell significantly below the IMO thresholds

Initial Situation

In order to halt the unintentional spread of organisms through ballast water the International Marine Organization (IMO) is establishing a convention which will in future regulate how ballast water is treated.

The convention should have been legally binding from 2012, latest from 2016 for new vessels. After 2016 the convention will become compulsory for all international ocean-going vessels.

The interim regulations are the D1 Ballast Water Exchange Standard and the D2 Ballast Water Performance Standard.

To ensure compliance with the convention the entire global fleet will gradually be fitted or retrofitted with ballast water treatment systems.


Our filter systems keep the ship’s engine running and help to reduce the environmental impact of shipping on the oceans. We masters the challenge of combining maximum performance with minimum space requirements.

The optimal product offering around separation, hydraulic filtration and bilge water de-oiling complements an excellent support service: If necessary, our technicians even stays on board to ensure the functionality of the filter systems at full speed minimizing the downtime of the vessel.

The efficiency of the individually e filters in the first stage can be adapted to the medium and requirements. There are potential applications in shipping, industry and in power plants.

Industrial filters for use in continuous operation

For production processes whose cost-effectiveness depend on continuous operation, We offers a wide range of automatic and process filters. They are extremely powerful, clean automatically and eliminate the need for chemicals to clean process fluids. With continuous development of materials and design, Industrial filters keep pace with increasing demands on product quality and component resistance during operation. By optimally cleaning lubricants and fuels as well as process and wash water, Our automatic and process filters increase the lifetime of machines. The required amount for process fluids gets reduced.

The high quality of the industrial filters guarantees maximum employee protection. It also guarantees a consistently high level of efficiency over a very long period of time.


Sewage Treatment Plants STP Series for marine applications are designed for the treatment of black (from WC, urinals, and hospital) and grey (sinks, showers, laundry and galley) water generated on board.

The treatment consists of the purification and subsequent disinfection of the water to achieve an effluent whose quality meets the IMO requirements.

The purification mechanism is based on a biological process of active sludge with extended aeration: the microorganisms in the biomass purify the water, so that no additional chemical treatment throughout the process is necessary.

The plants are built in a single steel module to ease transportation and on-board installation. The module is divided into three chambers (aeration, settling and discharge/disinfection), each of them with their respective inspection accesses.
