Single Stage Desalination Plants

Wärtsilä’s Single Stage Desalination (SSD) plant generates high quality freshwater in an energy efficient way. With a capacity from 8 to 35 tons/day, it is ideal for converting seawater for use as drinking or technical water onboard ships or offshore installations. 

The Wärtsilä SSD is a state-of-the-art desalination unit that meets the need of long-voyage seagoing vessels where freshwater cannot be bunkered. It is also applicable in situations where clean water is required for processes. The system uses vacuum distillation to remove salt and other impurities from the seawater and convert it into high quality freshwater (< 4 µS/cm). The design features simple technology for continuous and user-friendly operation. Waste heat from the diesel engine or other heat sources is used to evaporate the seawater. 
 
The SSD produces freshwater of the highest quality, simply and reliably. It is easy to operate, requires minimal maintenance. Spare parts are easily accessible, and no special consumables are required. Operating costs are low, and the use of time consuming manpower is extremely limited. Like all Wärtsilä installations, the SSD is supported by the marine industry’s most extensive global service network. 

 
The Single Stage Desalinator is Wärtsilä's plug-and-play freshwater generator. Simple. Reliable. Easy to install, operate & maintain.

    WORKING PRINCIPAL

    Seawater is fed into the system, passing through the condenser (1) and air-brine ejector (2). A small part of the seawater is used as feedwater for the evaporator. The air-brine ejector, driven by the seawater, evacuates both the excessive feed water and the chamber. A heating medium is fed into the evaporator. After approximately 5 minutes a vacuum of 90% is reached and evaporation of the feed water commences. The vapour flows through a demister (3) and is condensed in the condenser section. The distillate is pumped out of the unit.
