Plate type Tubular Performance % 1  2 125 100 75 Time Performance through time Alfa Laval Plate type evaporators can be cleaned 100% Tubular evaporators gradually decrease performance  because of “irreversible” scaling/fouling CIP cleaning can remove alkaline soft scaling, and  hard scaling can also be removed 100% in a PHE type desalination unit. Why use Plate MED?
Think Differently-District Cooling and Desalination
How do we “Raise“ heat from 2C to 90C? Interstage @ 58C HOR = 14.05MW R eff = 9.61MW COPh = 3.16
90 ˚C Ammonia Heatpump
The World’s Largest 90C Natural Heatpump?

Editor's Notes

  1. An extensive desalination History
  2. Multi Effect Tube unit Design Capability and Plate design technology => MEP UNIT ! Core product in desalination
  3. Updated map
  4. Project “Iskenderun Bay” Turkey Multi-Effect Plate, Thermo-Vapour Compression, 3 x TVC-4-1750 Powered by 15 bar bleed steam from the power plant turbines Boiler make-up water, flue gas cleaning and other process requirements
  5. Location: Jeddah Saudi Arabia Customer: Binzagr CO-RO New industrial Zone Jeddah Saudi Arabia Brief description: The customer is an industrial plant producing soft drinks and beverages. The systems installed are two Mechanical Vacuum Vapour Compression units desalinating underground water which has a higher salinity chemical complexity than the Red Sea. The produced water is the basis for blending of concentrates in the preparation and bottling of the final product. Main data: Water desalination Capacity: 475 M³/day Raw water source: High salinity underground water Type of desalination units: Vacuum Vapour Compression Number & size of units: 1 x 350 M³/day and 1 x 125 M³/day Specific energy consumption: 11 kWh/m³ of product Heat transfer surface material: Titanium Gr.
