APV Desalination unit - WDU
The water desalination unit is a single stage, plate type evaporator and condenser, separated by stainless steel demister. The H-CE unit is available in four sizes with capacities ranging from 20m³/24h to 33m³/24h. Working principle The vessel with evaporator and condenser is evacuated to -0,93 bar by the seawater-driven ejector. At this pressure, the seawater to be distilled enters the evaporator where it evaporates at approx. 44°C - 49°C when passing the plates heated by the heating medium - typically hot water (engine jacket water) at 75°C - 90°C. The steam leaves the evaporator through the open side of the plate pack and passes through a demister, where any carry-over drops are separated for re-circulation, and then enters the condenser positioned above. The clean vacuum steam is condensed into freshwater by circulating cold water on the other side. The freshwater is pumped to the freshwater tank, passing a sensor connected to the salinometer. If the salinity is higher than the pre-set reference value the solenoid valve is activated and the flow is directed back for re-production. Standard equipment The APV H-CE Water Desalination Unit includes Titanium plate heat exchangers for evaporator and condenser, vessel, seawater ejector, freshwater pump, freshwater meter, frame, control panel with motor starters and salinometer, and dosing unit for anti-scaling. ~ The water desalination unit is a single stage, plate type evaporator and condenser, separated by stainless steel demister.
