Alfa Laval MEP

Multi-Effect Desalination

Large-Scale Freshwater Solutions for Marine & Offshore Needs

Freshwater is a critical resource on every vessel, essential not only for crew consumption but also for a wide range of technical and operational processes. The Alfa Laval MEP (Multi-Effect Plate) freshwater generator provides a dependable supply of high purity water, engineered to perform efficiently under variable and demanding sea conditions.

Supply

We can supply brand new fresh water generators directly to your site or vessel. All units are quality-checked and tested to ensure they meet OEM standards.

Installation

Alfa Laval engineers ensure seamless integration into your system. Whether it’s a retrofit or part of a new installation, we handle every aspect with precision and efficiency.

Servicing

We provide full servicing, including inspections, bowl cleaning, seal replacements, and emergency repairs to keep your separator running efficiently.

Fresh Water Generation

Smart desalination for any capacity.

About the Alfa Laval MEP System

The MEP freshwater generator delivers large scale production capacity of 180 to 1,000 m³ per day, making it the ideal solution for vessels and offshore facilities with significant freshwater demands.

Its multi effect evaporation process achieves high output while keeping thermal and electrical power consumption low, maximising efficiency. Unlike conventional systems, the MEP maintains consistent performance even in cold seawater or shallow water conditions.

Its durable design also enables operation directly on the steam outlet of turbine generators, further optimising onboard energy use.

MEP

Produces distillate with a purity of 5–10 ppm, delivering clean, safe water for both potable and technical use. By harnessing waste heat for freshwater production, the MEP reduces fuel costs and minimises environmental impact.

  • Type: Multi-effect distillation system (MED with plate technology)
  • Function: Produces fresh water from seawater by multiple stages of evaporation and condensation
  • Application: Large vessels, offshore platforms, and land-based desalination where high-volume freshwater is required
  • Multi-Effect Design: 3–6 evaporation/condensation stages for maximum heat recovery
  • Heating Source: Waste heat from main engine jacket water, steam, or hot water
  • Plate Technology: Titanium plate heat exchangers replace traditional tube bundles → compact & efficient
  • Vacuum Operation: Enables evaporation at low temperatures (50–70°C), reducing scaling
  • Automation: Fully automatic PLC with monitoring and salinity control
  • Capacity: ~50 – 3,000+ m³/day (depending on model and number of effects)
  • Energy Efficiency: Extremely high; uses same heating energy across multiple stages
  • Operating Temp: Works with low-grade waste heat (~50–70°C)
  • Freshwater Quality: <2 ppm TDS (potable/technical water)
  • Mineraliser for drinking water hardness adjustment
  • UV steriliser or chlorination system
  • Freshwater pumps, ejector pumps, and dosing units
  • Remote monitoring and integration with ship automation systems
  • Very high efficiency thanks to multi-effect heat recovery
  • Low operating costs due to reduced energy demand
  • Compact & lightweight compared to tube-type MED plants
  • Scalable output → suitable for medium to very large vessels or platforms
  • Reliable, automatic operation with minimal crew involvement
