"High-Concentration Reverse Osmosis System "Pressure Redefined. Recovery Redefined."
Technology Type Ultra-High Pressure Reverse Osmosis (UHP-RO)
HCRO™ is a next-generation reverse osmosis system engineered for the high-recovery treatment of high-salinity and high-TDS water streams, including challenging brines and industrial wastewaters.
Powered by Ultra-High Pressure (UHP) membrane technology, HCRO™ operates at pressures up to 120 bar (1,800 psi)—significantly exceeding the capabilities of conventional RO systems. This enables:
- Concentration of hypersaline streams
- Minimized brine volume for downstream ZLD or evaporation
- Enhanced water recovery from seawater, brackish, or industrial sources
With its advanced design and robust materials, HCRO™ pushes the boundaries of what membrane-based treatment can achieve, offering a cost-effective, energy-efficient, and scalable solution for extreme water treatment challenges.
BrinePure™
As water recovery increases to extreme levels, scaling ions and organics reach high concentrations and can cause severe membrane fouling under ultra-high pressure. To mitigate this risk, InfraCorp has developed its proprietary BrinePure™ technology — an innovative brine refinement system that stabilizes the concentrate and protects the membranes, ensuring sustainable long-term operation at peak recovery rates.
KEY BENEFITS
- Treats Challenging Waters – Enables recovery from high-salinity brines and waste streams that traditional RO can’t handle
- Supports ZLD Goals – Reduces the volume of brine requiring evaporation or crystallization
- Compact and Scalable – Smaller footprint and modular design reduce installation and OPEX costs
- Energy-Efficient Design – Optimized for pressure recovery and minimal energy consumption per m³ treated
- Prolonged Membrane Life – Designed to operate under stable high-pressure conditions with enhanced durability
- Minimizes Environmental Impact – Less residual waste and lower chemical usage compared to thermal alternatives
HCRO™ FOR LITHIUM RECOVERY
Ultra-High-Pressure RO for Concentrated Performance in Critical Mineral Extraction
As global demand for lithium surges, producers are under pressure to improve yield, efficiency, and sustainability. HCRO™ provides a high-performance membrane solution for lithium-rich brine concentration, integrating seamlessly into direct lithium extraction (DLE) or evaporation-based flowsheets.
Maximize Lithium Yield
HCRO™ can concentrate lithium-bearing brines to 3x–6x their original strength, improving the efficiency of downstream DLE or crystallization steps and enhancing overall lithium recovery.
Preserve Critical Chemistry
Unlike thermal methods, HCRO™ operates without altering brine chemistry, maintaining the ionic balance critical to selective lithium extraction technologies.
Reduce Volume, Reduce Cost
By reducing total brine volume by up to 75%, HCRO™ minimizes evaporation pond requirements, thermal system load, and disposal costs—leading to lower CAPEX and OPEX.
Energy-Efficient Brine Concentration
Operating at up to 120 bar (1,800 psi), HCRO™ delivers membrane-based separation with far lower energy intensity than traditional thermal systems—ideal for off-grid or renewable-powered operations.
Built for Harsh Chemistry
HCRO™ uses high-pressure, corrosion-resistant materials and membranes optimized for high-TDS, high-Mg/Ca brines, ensuring robust performance in lithium trianglesalars, geothermal fluids, and processed reject streams.
