Treatment Technology
Alfa Laval PureBallast 3 uses an enhanced form of UV treatment, developed in cooperation with Wallenius Water. It performs without the addition of salt or chemicals, even when operating in fresh water.
Biological disinfection
Biological disinfection, which is the main treatment process, occurs within an enhanced UV reactor. The reactor has a flow-optimised interior that ensures high turbulence and concentration of the UV dose. The medium-pressure UV lamps within the reactor employ specially designed lamp sleeves of synthetic quartz. These unique sleeves support transmission of a broader wavelength spectrum and provide more UV light during disinfection. Combined with the reactor's internal design, this ensures optimal UV dosage and low energy consumption.
Filtration
Supporting the reactor is a filter stage, used to remove any larger organisms and particles prior to biological disinfection. This improves the quality of water for treatment, especially when operating in cloudy coastal waters and fresh water. Combined with the reactor, the effective basket filter design enables full-flow treatment of fresh, brackish and marine water with UV transmittance as low as 42%.

Support Components
Additional components are support systems that can be flexibly placed for an optimal design.
- Electrical cabinet
- Compact Cleaning-In-Place (CIP) unit
- LDC1/LDC2 for flows above 300m3/h
There is a broad range of auxiliary equipment to support integration into any vessel including backflush pumps, sampling points, valve packages and remote control panels.
COMPACT
Alfa Laval PureBallast 3 Compact can be delivered as a skid-mounted module making it compact and easy to install due to minimized pipework. The skid has a minimal footprint and is connected via simple plug-and-play contacts. For flows of 32-300 m3/h.
All components are incorporated into the skid, apart from an electrical cabinet that is flexibly placed. This cabinet is a combination of the lamp drive cabinet and control cabinet of larger systems.
The following components are incorporated into the PureBallast 3 Compact skid-mounted:
- Filter
- Reactor
- Compact Cleaning-In-Place (CIP) unit
- Electrical cabinet, is flexibly placed up 30m from UV-reactor
There is a broad range of auxiliary equipment to support integration into any vessel, including backflush pumps, sampling points, valve packages and remote control panels.
Ex systems
PureBallast 3 is available in a range of Ex configurations including Zone 1, IIC and T4 compatibility. Ex designs are simplified by the flexible placement of the lamp drive cabinets, which can be located outside the hazardous zone and up to 150m away from the reactors they serve.
Certain standard features are also relevant to Ex systems. For example, reactor temperature and level sensors are connected via safety relays that bypass the PLC, preventing their signals from being missed in the unlikely event of a PLC malfunction.
