- Pretreatment: Filter seawater or brine and adjust concentration for evaporation.
- Evaporation: Low-pressure boiling generates secondary vapor and concentrate.
- Mechanical recompression: The secondary vapor is compressed and returned as the heating medium.
- Crystallization & separation: Salt crystals form as brine concentrates; recover via filtration or centrifugation.
- Drying & packaging: Dry crystals and pack for storage or sale.
- Ultra-low energy use: typically 15-50 kWh per ton of water evaporated (design-dependent).
- Gentle heating: small ΔT operation reduces product degradation.
- Compact footprint: ~50% less floor area than traditional multi-effect units.
- Clean utilities: no live steam consumption; low cooling-water demand; no boiler flue gas plume.
- Flexible turndown: stable at low load; long service life.
- Low-temperature capability: evaporation possible below 40°C—ideal for heat-sensitive products.
