Almost as easy as plug and play! It is one of the ﬁrst ballast water management systems on the market that combines very low space with large ﬂow rates. Only 2.8 m2 / 30 sqft is necessary for a 1000 m3/h / 4403 gpm system + 0.6 m2 / 6.4 sqft for the electrical panel, which can however be placed up to 100 m / 328 ft away from the system itself.

The system is based purely on mechanical treatment and therefore it does not involve any use of chemicals or active substances. This eliminates risks of hazards to crew, vessel or the environment.
First treatment step is ﬁltration, second step is UV treatment. During de-ballasting, UV treatment is repeated, but the filtration step is skipped.
Smooth Port Operations
Automatic adjustment of treatment in order to cope with extremely challenging water, avoiding alarms and interrupted port operations in dirty and challenging water conditions.
High Efficiency Keeps your OPEX Down
Patent pending UV unit design with very high treatment efficiency reduces the power consumption.
The CompactClean filter backflush pump can be used as stripping pump during stripping of ballast tanks.
Fully Automated with Easy Integration into Ship Automation System
CompactClean is PLC controlled and supports all generally used main types of communication interfaces.
Long Lifetime of Components Gives you Reliable Treatment and Low OPEX
UV unit made of Nickel-Alu-Bronze material with superior corrosion resistance and proven very long lifetime.
The System is Delivered with a Standard Electrical Panel. Additional Remote HMI Screen on e.g. Bridge or in Engine Control Room can be Added.
The BWMS is delivered with a main panel that can be placed in any convenient place. The main panel is equipped with an HMI screen, from which the system is controlled and alarms are visualized. All operations can be done from a secondary screen in the deck control office or on the bridge, if option for installing remote control screens is used.
Standard fully automated operating modes for treatment are:
- Other automated modes which can be selected are:
- Water Filling
On the HMI screen, the operator can switch between several screen views (main page, active alarms, alarm history, PI-D page and UV drivers) to display all relevant information. During operation, the status of all components and sensors can be monitored, and operational values such as flow, pressure, temperature and UV intensity can be viewed instantaneously; and trend curves can be displayed to see the development over time.
What is UV Transmission?
UV-T is a measure of the capability of UV light to penetrate water. When the UV-T is high, close to 100%, the water is very clear and the UV light can penetrate deep into the water. On the other hand, when the UV-T is low, the water is very unclear and the UV light can only penetrate a limited distance into the water.
Clearly, the UV-T of the water to be treated is of utmost importance. To kill or render an organism non-viable, a certain UV dose is required, and the applied UV dose is directly proportional with the UV intensity. Therefore, when the UV-T is low, significantly more UV power is needed to treat the water according to the required discharge standards.

Limitations of Ballast Water Management Systems
It should be acknowledged that all BWMS have limitations. Typically, chemical systems (e.g. electro-chlorination) have limitations related to the salinity of the water to be treated, its temperature or the amount of organic material contained in the water; whereas UV based BWMS have limitations with regard to the UV transmission of the water to be treated. In other words, all BWMS have special circumstances under which they cannot be expected to treat the water according to the IMO and USCG discharge standard. The trick for the ship owner is to select a BWMS that will work under normal operational conditions.

UV Transmission of Ballast Water
The UV-T found in different ports around the world varies significantly. Some ports are located at river estuaries, which means that the water in the port is fresh water containing high amounts of sediments, organic particles and dissolved organic compounds. This makes the UV-T very low. Other ports are located on islands in the middle of an ocean, and here the UV-T is typically high. In the same port the UV-T can vary from day to day depending on tide, weather (rain and strong wind), and season.
