Alfa Laval PureBallast 3.1 Ballast water treatment system Alfa Laval PureBallast 3.1 is an automated inline treatment system for the biological disinfection of ballast water. Operating without chemicals, it combines initial filtration with an enhanced form of UV treatment to remove organisms in accordance with IMO and USCG limits. The main component of the modular system is an enhanced UV reactor in which disinfection treatment occurs. The special design of the reactor’s synthetic quartz lamp sleeves supports transmission of a broader wavelength spectrum, providing 10% more UV light during disinfection. Combined with the reactor’s internal design, this ensures optimal UV dosage and low energy consumption. Application PureBallast 3.1 is designed for ballast water treatment in all types of water: fresh, brackish and marine. Upon request, it can also be configured as a two-water solution for brackish and marine water. Flows of 32-3000 m3/h can be accommodated by a standard system. Due to its enhanced UV technology and power ramp-up capabilities, PureBallast 3.1 provides unmatched biological disinfection performance in low-clarity waters. Full-flow treatment is possible in waters where the UV transmittance is as low as 42%.

Benefits • Superior performance in any waters PureBallast 3.1 offers unmatched biological disinfection performance in any type of water: fresh, brackish or marine. This includes water in liquid form at frigid temperatures. Even in low-clarity waters with UV transmission of just 42%, the system performs at full flow. This gives vessels full freedom of movement without operating constraints. • Effective power management Because of its high biological disinfection performance, PureBallast 3.1 runs at just 50% of its potential operating power in most situations. It can be ramped up to full...

System components – biological disinfection Biological disinfection with PureBallast 3.1 comprises an initial filtration stage followed by enhanced UV treatment in a specially designed reactor. Both stages are integrated into the ballast water piping as inline components. • Filter A filter is used during ballasting operations to block the intake of larger organisms and reduce sediment in the ballast water tanks. Bypassed during deballasting, the filter is cleaned via automatic backflushing using a small portion of the system flow. Two filter types are available: - Basket filter design...

Operating sequence • Ballasting PureBallast 3.1 is a fully automated system. When initiated, it undergoes a brief startup sequence. When ballasting begins, the incoming ballast water first passes through the filter stage. This removes any larger organisms and particles, which improves the quality of the water for treatment. The filter stage is of benefit for operation in cloudy coastal waters and fresh water. After filtration the water continues through the reactor stage, where it is disinfected by means of enhanced UV before entering the ballast water tanks. Once ballasting is complete,...
