Nanofiltration

Nanofiltration membranes selectively reject divalent ions (calcium, magnesium, sulfate) and organic compounds while passing monovalent ions like sodium and chloride. This makes NF ideal for softening, colour removal, and partial desalination applications where complete TDS removal isn't necessary or economical.

Compared to reverse osmosis, NF operates at lower pressure and higher flux, reducing energy consumption — a meaningful economic advantage when full desalination isn't the goal.

Electrodialysis Reversal

EDR uses an electric field to drive ion migration through ion-selective membranes, separating dissolved salts from water. Periodic polarity reversal disrupts scale formation on membrane surfaces, giving EDR systems exceptional robustness against fouling and scaling compared to pressure-driven membrane processes.

This makes EDR particularly well-suited to high-scaling brines — produced water, mine-impacted water, and other feedstocks where conventional RO would require extensive chemical pretreatment.

Ion Exchange

Ion exchange resins offer highly targeted removal of specific contaminants — hardness, silica, heavy metals, boron, and selective ions like lithium or specific radionuclides. Conclusive deploys IX as a standalone solution for polishing duties or in combination with membrane processes for primary treatment.

For direct lithium extraction applications, selective IX resins are central to separating lithium from competing cations in complex brine matrices.

Advanced Reverse Osmosis

Conventional RO systems struggle with high-TDS, high-temperature, or high-scaling feedwaters. Conclusive's advanced RO designs — incorporating high-pressure configurations, optimized staging, and tailored antiscalant strategies — extend the practical operating envelope of membrane desalination into territory most off-the-shelf systems can't reach.

The result: higher recovery rates, longer membrane life, and lower overall lifecycle cost for difficult industrial feedwaters.

MVR Evaporation

Mechanical vapour recompression (MVR) evaporation compresses and reuses vapour generated during evaporation, dramatically reducing the energy intensity of thermal concentration compared to conventional multi-effect evaporation. This makes MVR an economically viable path to zero liquid discharge (ZLD) for high-TDS brines that have exhausted membrane-based concentration options.

MVR systems handle the brines that membranes can't — concentrating reject streams toward saturation ahead of crystallization or disposal.

Crystallization

The final step in many resource recovery pathways, crystallization converts concentrated brines into solid, product-grade salts and minerals — lithium carbonate, sodium sulphate, sodium chloride, and others — turning what would otherwise be a costly waste disposal liability into a marketable commodity.

Crystallizer design and operating conditions are tailored to target product purity, crystal habit, and downstream handling requirements.

Clarification & Filtration

Effective downstream membrane and thermal systems depend on consistent upstream water quality. Conclusive designs clarification and filtration pretreatment — lamella clarifiers, dissolved air flotation (DAF), media filtration, and ultrafiltration — configured to your specific feed conditions to protect capital-intensive downstream equipment and reduce fouling-related downtime.
