Product Description

Reverse Osmosis Fresh Water Generator/ Seawater Desalination
Based on the general design scheme, the Fresh Water Generator which mainly consists of evaporating and condensing chambers, ejector equipped for vacuum, as well as relevant accessories for the system. 
Furthermore the whole control system is to be designed as maker standard in according to our 
Design purpose. Subject salinity meter is exclusively composed by maker, the design scheme 
Concludes with temperature compensation. 

The system designed under rough sea condition. That is for 32 0C sea water and 75 0C cylinder 
Jacket cooling water. Under such circumstance, the unit can reach distillate production capacity of 
20 t/d. Each unit consists of a condenser and an evaporator installed in a same chamber. 

Characteristics of Fresh Water Generator: 
T he plant is a packaged unit, which is mounted on a base frame. All components and accessories 
Such as fresh water pump, interconnecting pipe-work as well as inner cable are connected prior to 
The sea water pump independently supplied for on-site installation on board, which is to be 
Positioned under the light ballast line. 

Technical Specification 
Theory description: 

The sea water enters the plant at the condenser for cooling the water vapor, flows through the 
Condenser. Then a little quantity is fed into the evaporating chamber and about half of them 
Evaporating to vapor, the sea water is heated by the cylinder cooling water of main engine. The rest quantity of sea water is led to the brine/air ejector, where brine and air is take off, and was 
Discharged to overboard. 

The pressure inside the chamber is less than atmosphere (vacuum), in this way the evaporating 
Temperature usually is lower than 45 degree. The vapor rises from the evaporating chamber, which 
Flows through the demister where brine mist is removed, and pure steam condensed to liquid in the
