PureScrub H₂O

Compact and modular, the PureSO_x H₂O water cleaning unit is an essential part of Alfa Laval’s PureSO_x hybrid or freshwater scrubber. But it is also available as a standalone product for use in wet scrubbers not designed by Alfa Laval. Proven under real-life operating conditions, PureSO_x H₂O uses centrifugal separation to clean scrubber water in compliance with IMO legislation. The automated unit is easy to operate, and it is available in different sizes to suit a variety of flow rates. All equipment comes installed and tested on a common frame, which is divided into three main blocks to simplify retrofit installations.

• Reliable reduction of solids content in the wash water – generally to well below the required 25 FTU
• Measurement, control and logging of Marpol Annex VI wash water criteria:
  • Acidity (pH)
  • Harmful components of oil (PAH)
  • Particulate matter (turbidity)
• Continuous operation with instant bleed-off and automatic chemical dosing only when necessary
• Flexible, modular design to meet the requirements of most vessel
• Competitive operating costs – low maintenance and waste volumes
• Safe, easy operation with automated control and monitoring
• Password switch for overboard discharge only by authorized personnel

Equipment (delivered as a unit):

• SWPX separator with ancillary equipment
• Scrubber water feed pump
• Chemical dosing pump with retention tanks
• Control cabinet

Reliable compliance

PureSO_x H₂O uses high-speed separation technology, which means continuous and highly reliable operation. It generally reduces the solids content of scrubber water to well below the required 25 FTU – even when subjected to varying engine conditions and rough weather. Dangerous particulate matter is cleaned from the scrubber system, while the waste volumes for disposal are kept to a minimum.
