Core Architecture
Stage 1
BrineX™
Pre-concentration to cut evaporator duty.
Stage 2
MEE
Stagewise thermal concentration.
Stage 3

BrineX Advantage
- Pre-concentrates reject before thermal stage
- Reduces thermal hydraulic load by ~30-50%
- Improves downstream sizing and runtime economics
MEE + MVR Thermal Core
- Stagewise heat reuse through effects
- Vapor recompression loop for lower steam use
- Stable operation under high-TDS reject variability
