Alfa Laval PureBallast 3 CompactSkid-mounted ballast water treatment system with minimal footprint Alfa Laval PureBallast 3 Compact is a third-generation PureBallast system designed for simple, plug-and-play installation. Like other PureBallast 3 systems, it is fully automated and uses an enhanced form of UV treatment for the biological disinfection of ballast water. (See the PureBallast 3 Compact Flex or PureBallast 3 Std leaflets for details.) The system is delivered as a compact module, which comes ready-assembled and mounted on a skid with all necessary equipment and prefabricated pipework. The module is easy to connect and is pre-tested before delivery. Application Type approved by IMO and the U.S. Coast Guard (USCG), PureBallast 3 Compact is certified for ballast water treatment in all types of water: fresh, brackish and marine. Even in low-clarity water, it provides unmatched biological disinfection performance. When operating in IMO-regulated waters, full-flow treatment is possible where the UV transmittance is as low as 42 %. PureBallast 3 Compact is specifically designed for compact installation and can be configured for flows of 32-300 m3/h. Type approvals • IMO (USCG upgradeable) PureBallast 3 Compact systems have IMO type approval. Note that when comparing IMO type approval certificates for different ballast water treatment systems, certificates issued before 2014 do not state the system limitations. If needed, IMO-certified PureBallast 3 Compact systems can be upgraded with USCG type approval at a later date. • USCG For vessels that need to discharge ballast in United States waters, PureBallast 3 Compact systems with USCG type approval are available. Standard USCG-certified systems have the same capacities as IMO-certified systems, but they may operate at reduced flow in United States waters with very low UV transmittance values. For vessels requiring full flow at all times, high-power USCG-certified (USCG HP) systems are available. Benefits* • Minimal system footprint • Simple installation as a plug-and-play skid • Certified performance in any type of water: fresh, brackish, marine • Excellent performance in low-clarity waters • Effective power management * Additional benefits and details can be found in the PureBallast 3 Compact Flex or PureBallast 3 product leaflets Skid components The following components are incorporated into the PureBallast 3 Compact skid: • Filter The filter is used during ballasting operations to block the intake of larger organisms and reduce sediment in the ballast water tanks. • Reactor Built with long-lasting super-austenitic stainless steel, the reactor comprises the enhanced UV treatment stage responsible for biological disinfection. • Compact Cleaning-In-Place (CIP) unit UV lamp performance is safeguarded by an automatic CIP cycle that removes UV-impairing fouling and scaling.

Electrical cabinet In PureBallast 3 Compact, the lamp drive cabinet and control cabinet are integrated into a single electrical cabinet. This cabinet provides power to the UV lamps and features a 7” display with a graphical user interface. The control system can be integrated with onboard automation systems via Modbus, allowing access to all functions through the vessel's Integrated Ship Control System. Ex placement PureBallast 3 Compact is configured for installation within the safe zone. For placement in the hazardous zone, a PureBallast 3 Ex system is required (see separate leaflet). Capacity...
