Compact Ballast Water Management System
Looking for a ballast water management system that can be easily installed without major rearrangements of other equipment? CompactClean is the answer.
Using a proven combination of filtration and UV radiation, the DESMI CompactClean system is the first ballast water treatment solution on the market that takes up so little space - and still delivers great flowrates. Only 2.8 sqm is necessary for a 1000 m3/h system + 0,6 sqm for the electrical panel, which can be installed up to 100 m from the system itself.
Compact Ballast Water Management System with just One Global Operation Mode
The selection of either IMO or US mode can be very complicated if the operator does not know where the ballast water taken on board is going to be discharged.
With the CompactClean Standard system, you do not need a special mode to comply with USCG requirements. You just have one global mode for worldwide operation.
The advantage of using a single operation mode globally is that it removes the need to know the de-ballast location at the time of ballast uptake. This means that the ship will never get into a situation where the ballast water on board is compliant for discharge in one location but not in another.

CompactClean Ballast Water Management System has a great number of special features
✔ Smooth Port Operations
✔
High Efficiency Keeps your OPEX Down
✔ Integrated and Compliant Solution for Ballast Stripping Operations
✔ Fully Automated with Easy Integration into Ship Automation System
✔ Intelligent Control
✔ Long Lifetime of Components Gives you Reliable Treatment and Low OPEX

Smooth port operations
Automatic adjustment of treatment to handle dirty or low-UV water without triggering alarms or halting discharge. This keeps port operations running smoothly and avoids costly delays.
High efficiency and low OPEX
The UV chambers in CompactClean are designed through extensive CFD simulations to achieve maximum treatment efficiency. By utilizing every kilowatt of UV light effectively, it reduces power consumption and operational costs.
Integrated ballast stripping solution
The CompactClean system uses its filter backflush pump as a dedicated stripping pump during de-ballasting, eliminating the need for ejectors. This ensures full IMO and USCG compliance and reduces wear by preventing untreated water from entering the system. One system, one pump – multiple functions.
Fully automated operation
PLC-controlled system integrates easily with ship automation. Simple one-touch operation for ballasting and de-ballasting ensures effortless compliance.
Durable construction
The CompactClean UV units are made of cast Nickel-Alu-Bronze with proven sea-water corrosion resistance. This ensures a long lifetime, minimizing maintenance and downtime.
