BWTS components from Optimarin combine top performance and reliability

In our ballast water treatment system, the filter plays a crucial role in removing particles from the seawater during ballasting or stripping operations. The filter mesh effectively captures larger particles and prevents them from entering the system.

Key features of our filter technology

Our filter is designed to remove larger particles and organisms from the seawater to ensure optimum water quality.

Minimal pressure drop: With a pressure drop of only 0.1 to 0.5 BAR, our filter ensures efficient flow rates without significant energy consumption.

Bypass function: During deballasting, the filter is intelligently bypassed, enabling smooth and fast water discharge.

Automatic self-cleaning: Our filter is equipped with an automatic self-cleaning function. By reversing the flow direction and flushing the untreated water back into the sea, continuous filter performance is guaranteed.

Filter types

Optimarin uses high quality filters in its Ballast Water Treatment Systems (BWTS) to ensure the efficiency and reliability of particle removal from seawater:

Filtrex filter: a basket type filter capable of filtering particles down to 20 microns in size. This filter is known for its high filtration efficiency and robustness.

The Optimarin backflush pump is an essential component of the ballast water treatment system. It is used to regularly clean the filter system and prevent blockages. The pump ensures that the filter is flushed through the backwash process at high pressure, removing accumulated dirt particles, sediment and microorganisms. This keeps the filter system efficient and functional, contributing to the overall performance of the ballast water treatment system. Backwash water does not have to be treated according to regulations

Robust and efficient pump technology

The backflush pump is a centrifugal pump with an electric motor. It is connected to the overboard line for filter backwashing and contributes to more efficient filter cleaning. It is started automatically when the filter needs to be backwashed.

Our systems utilise strong UV light to efficiently eliminate organisms in the ballast water. Each chamber treats up to 167 m³/h of water. By installing the chambers in parallel, almost unlimited capacities are possible to ensure maximum efficiency and performance.

Key features of our UV technology

• High-performance UV lamps that efficiently inactivate organisms, bacteria and pathogens in ballast water and ensure excellent treatment results.
• The system consists of one or more UV chambers installed in parallel. Each chamber consists of a single CuNi Fer 90/10 DN150 pipe with a robust wall thickness of 3 mm.
• Each UV chamber can effectively treat up to 167 m³/h of ballast water thanks to the implementation of a high-power UV lamp. With a maximum UV lamp output of 35 kW, our system offers exceptional performance.
• The chambers are equipped with UV and temperature sensors to ensure precise monitoring and control as well as real-time data acquisition and adjustments.
• Our system uses a standardised UV chamber design that can be installed in parallel on a single rack. This configuration allows for higher flow rates and improves system scalability.
• Our UV system is designed for minimal maintenance requirements and ease of operation. It requires no chemical cleaning and has no moving parts, ensuring trouble-free use.
• Each chamber can handle a maximum flow rate of 167 m³/h in all modes, ensuring efficient treatment performance.
• In IMO mode, no hold time is required, allowing for continuous flow and operation. In USCG mode, the hold time is reduced to 24 hours.

Our pressure control valves regulate the pressure of your ballast water treatment system extremely reliably and efficiently, contributing to the overall efficiency and safety of the system. With electric flow-pressure valve technology, you experience the latest advances in valve control, technology and acoustics.

Key features of our pressure control valves

• The electric Flow Pressure Valves (FPV) have a compact design with a diameter of DN350 at only 193 mm, which enables efficient use of space.
• Weighing only 130 kg for DN350, the FPVs are very light and reduce the overall weight of the system.
• The valves consist of a butterfly valve with a rubber seat and a bronze-aluminum disc. The flow element is made of stainless steel for durability and reliable performance.
• The FPV is electrically actuated and provides precise control and reliable operation.
• The actuator is designed with a fixed control speed, ensuring consistent performance regardless of pressure fluctuations.
• Fluctuating pressure has no effect on the control, so the electric FPV maintains its effectiveness and accuracy.

By integrating a multi-tooth element into the butterfly valve body, the control performance is excellent. The tooth profiles ensure a uniform flow characteristic and make valve control precise and simple.
