Filters for optimal water quality and efficient flow rates
In our ballast water treatment system, the filter plays a crucial role in removing particles from seawater during the ballast or stripping processes. The filter fabric 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 seawater, ensuring optimal water quality.
Minimal pressure loss: With a pressure loss of only 0.1 to 0.5 BAR, our filter ensures efficient flow rates without significant energy consumption.
Bypass function: During ballast water discharge, the filter is intelligently bypassed, allowing for smooth and quick water discharge.
Automatic self-cleaning: Our filter is equipped with an automatic self-cleaning function. By reversing the flow direction and backflushing untreated water into the sea, continuous filter performance is ensured.
Filter types
Optimarin uses high-quality filters in their ballast water treatment systems (BWTS) to ensure the efficiency and reliability of particle removal from seawater:
Filtrex Filters: A basket-type filter that can filter particles down to a size of 20 microns. This filter is known for its high filtration efficiency and robustness.
If you have any questions about our filters, we are happy to assist you with our comprehensive consulting services.
Optimal filter performance with Optimarin backflush pumps

The backflush pump from Optimarin is an essential component of the ballast water treatment system. It is used to regularly clean the filtration system and prevent blockages. The pump ensures that the filter is backflushed under high pressure, removing accumulated dirt particles, sediments, and microorganisms. This keeps the filtration system efficient and operational, contributing to the overall performance of the ballast water treatment system. Backflush water does not need 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 backflushing and contributes to more efficient filter cleaning. It is automatically activated when a filter backflush is required.

Powerful UV systems for optimal ballast water treatment

Our systems use strong UV light to efficiently eliminate organisms in ballast water. Each chamber treats up to 167 m³/h of water. By installing the chambers in parallel, virtually unlimited capacities are possible, ensuring maximum efficiency and performance.
Key Features of Our UV Technology
- High-performance UV lamps efficiently inactivate organisms, bacteria, and pathogens in ballast water, ensuring excellent treatment results.
- Das The system consists of one or more UV chambers installed in parallel. Each chamber is made from 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-performance UV lamp. With a maximum UV lamp power of 35 kW, our system delivers exceptional performance.
- The chambers are equipped with UV and temperature sensors to ensure precise monitoring and control, enabling real-time data acquisition and adjustments.
- Our system utilizes a standardized UV chamber design, which can be installed in parallel on a single rack. This configuration allows for higher flow rates and enhances the scalability of the system..
- Our UV system is designed for minimal maintenance requirements and ease of operation. It does not require chemical cleaning and has no moving parts, ensuring hassle-free usage.
- Each chamber can handle a maximum flow rate of 167 m³/h in all modes, ensuring efficient treatment performance.
- In IMO mode, no holding time is required, allowing continuous flow and operation. In USCG mode, the holding time is reduced to 24 hours.

Precise pressure control valves for your ballast water treatment system

Our pressure control valves regulate the pressure of your ballast water treatment system with exceptional reliability and efficiency, contributing to the overall efficiency and safety of the system. With electric flow-pressure-valve technology, you experience the latest advancements in valve control, technology, and acoustics.
Key Features of Our Pressure Control Valves
- The electric Flow Pressure Valves (FPV) feature a compact design with a diameter of DN350 at only 193 mm, allowing for efficient use of space.
- With a weight of just 130 kg for DN350, the FPVs are very lightweight, reducing the overall weight of the system.
- The valves consist of a shut-off flap with a rubber seat and a bronze-aluminum disc. The flow element is made of stainless steel, ensuring durability and reliable performance.
- The FPV is electrically operated, providing 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 shut-off flap body, the control performance is excellent. The tooth profiles ensure a logarithmic flow characteristic, making valve control precise and easy.
