Alfa Laval PureBallast 3 Compact Flex Ballast water treatment system with full installation flexibility and minimal footprint Now in its third generation, Alfa Laval PureBallast is an automated inline treatment solution 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 stipulated limits. Application Type approved by IMO and the U.S. Coast Guard (USCG), PureBallast 3 Compact Flex is designed for ballast water treatment in all types of water – fresh, brackish and marine – and is available for flows of 32–1000 m3/h.* 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 more UV light during disinfection. Combined with the reactor’s internal design, this ensures optimal UV dosage and low energy consumption. Due to its enhanced UV technology and power ramp-up capabilities, PureBallast 3 Compact Flex provides unmatched biological disinfection performance in low-clarity waters. When operating in IMO-regulated waters, full-flow treatment is possible where the UV transmittance is as low as 42%. This leaflet covers PureBallast 3 Compact Flex, a system of loose components, designed for simple, plug-and-play installation where space is vital. The system offers space savings of up to 20% compared to PureBallast 3 Std. * Larger capacities are possible with PureBallast 3 Std, which can be configured for flows up to 3000 m3/h with a single system or even higher with multiple systems (see separate le

Benefits • Superior performance in any waters PureBallast 3 Compact Flex offers unmatched biological disinfection performance in any type of water: fresh, brackish or marine. This includes water in liquid form at frigid temperatures. In addition, the system excels in low-clarity water conditions. When operating in IMO-regulated waters, it performs at full flow where the UV transmittance is as low as 42%. • Ease of use PureBallast 3 Compact Flex is fully enclosed, fully automated and thoroughly integrated with the ballast water system. It requires no manual intervention. • Effective power management...

Treatment components Biological disinfection 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 The 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. This not only improves backflushing efficiency, but also increases overall filter effectiveness by producing...

Operating sequence • Ballasting The ballast water treatment process is fully automated. When initiated, the system 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...
