Hot water. Critical minerals. Cleaner separation.
GREENVI™ is developing next-generation membrane products for demanding industrial water treatment and lithium recovery. The product platform focuses on high-temperature reverse osmosis for SAGD and thermal process waters, and lithium-selective nanofiltration for complex brine streams.
RO module element
Manufacturing line
HTRO module
Two platforms built for high-value separations.
HTRO membranes for hot, complex industrial water.
Designed for elevated-temperature water streams where conventional RO membranes can lose stability, lifetime, and rejection performance.
- Targets SAGD produced water, boiler blowdown, geothermal, mining, and power-generation streams.
- Engineered around thermally stable thin-film composite membranes and compatible spiral-wound modules.
- Focused on water reuse, salt rejection, silica control, and reduced treatment complexity.
Lithium selective membranes for complex brines.
A thin-film composite nanofiltration platform designed to separate lithium from competing divalent ions such as magnesium and calcium.
- Supports lithium brine processing, DLE polishing, battery recycling, and lithium-containing industrial streams.
- Designed to reject Mg2+ and Ca2+ while maintaining lithium passage for downstream recovery.
- Canadian and U.S. patent applications have been filed for the platform and fabrication methods.

Testing equipment
From membrane formulation to deployable modules.
The product roadmap follows a staged development path: formulation discovery, laboratory characterization, bench-scale filtration and IP protection, pilot-scale validation, spiral-wound module manufacturing, and field demonstration.
Formulation discovery
Identify membrane chemistries and supports for target separations.
Fabrication and characterization
Validate permeability, rejection, stability, fouling, and process fit.
Bench testing and IP
Conduct filtration tests, refine formulations, and protect core technology.
Pilot validation
Demonstrate performance in relevant water and brine environments.
Module demonstration
Manufacture spiral-wound modules and validate deployable technology.
Bring us the stream. We will help define the membrane pathway.
GREENVI™ is seeking industrial partners for water chemistry review, membrane testing, pilot validation, and application-specific module development.
