Technology
Brine concentration to 280,000 mg/L on membranes
Three proprietary reverse-osmosis processes, each designed for its own salinity range, take a stream from dilute feed to crystallizer-ready brine. The thermal stage that remains is sized for a fraction of the flow.
mg/L TDS
| Lane | Range | From (mg/L TDS) | To (mg/L TDS) | Note |
|---|---|---|---|---|
| SEBRO | SEBRO | 0 | 25,000 | Dilute brines |
| SAMRO | SAMRO | 20,000 | 90,000 | Mid-range, adaptive |
| MBC | MemBrine Concentrator | 90,000 | 280,000 | 5–12 kWh/m³ |
| Crystallizer | Crystallization | 280,000 | 300,000 | The residue only |
Solutions
Membrane concentration for zero liquid discharge, mineral recovery, lithium, and produced water.
Minimum and zero liquid discharge
Membrane concentration ahead of crystallization, so the thermal plant is sized for the residue only.
Brine mining and resource recovery
Concentration of desalination and industrial brines for the recovery of magnesium, potassium, bromine, and salts.
Lithium
Concentration of lithium brines and DLE eluate to crystallization strength, in months rather than years.
Produced water
Volume reduction and water recovery for oilfield produced water, lowering transport and disposal cost.
60–75% lower energy and capital than the thermal train it replaces
- Concentration ceiling
- 280,000mg/L
- Against about 90,000 for conventional RO
- Brine concentration energy
- 5–12kWh/m³
- Against 25–60 for thermal evaporation
- Water recovery
- 99%+
- Across the full membrane ZLD train
- Smaller footprint
- 70%
- Than a conventional thermal system
