Did you know
- Alfa Laval PureBallast 3.0 was launched in April 2013, building upon two decades of experience with PureBallast technology, which was the first commercially available ballast water treatment solution.
- The PureBallast 3 series includes several models tailored for different vessel needs. The PureBallast 3 Compact and PureBallast 3 Compact Flex are designed for smaller vessels and installations where space is limited, offering a minimal footprint. The PureBallast 3 Std and Ex models cater to a wider flow range and hazardous environments, respectively. The PureBallast 3 Ultra, introduced in Q3 2025, represents the latest evolution, offering enhanced performance in challenging waters and further power savings.
- PureBallast 3 is chosen for its chemical-free operation, utilizing an enhanced UV treatment combined with filtration to neutralize organisms across all water salinities (fresh, brackish, and marine). It is recognized for its energy efficiency, with some configurations offering up to 60% power savings over previous versions, and its ability to maintain full-flow treatment even in low-clarity waters with UV transmittance as low as 42%.
| Model | Flow Rate (m³/h) | Power Consumption (kW per 1000 m³/h) | Footprint Reduction vs. PureBallast 3 Std |
|---|---|---|---|
| PureBallast 3 Std & Ex | 250–3000 (single system), up to 6000 (dual systems) | 100 (at full power) | N/A |
| PureBallast 3 Compact Flex | 32–1000 | 52 (at full power for 1000 m³/h reactor) | Up to 20% smaller |
| PureBallast 3 Compact | 32–300 | 17 (optimal for 250/300 m³/h) | Minimal footprint (skid-mounted) |
