HTRO membranes for hot industrial water.
GREENVI™ is developing High-Temperature Reverse Osmosis membranes and modules designed to treat challenging industrial water streams at elevated temperatures, including SAGD produced water and thermally demanding process waters.
High-Temperature Reverse Osmosis (HTRO) Element
Treating hot, saline, silica-rich water is hard.
SAGD and thermal operations require large volumes of water for steam generation. Produced and process waters can contain high salinity, silica, hardness-forming ions, organic foulants, and temperatures around or above 90°C.
What HTRO is designed to address
- Elevated-temperature operation beyond conventional Reverse Osmosis (RO) limits.
- High dissolved solids, silica, hardness, and organic compounds.
- Membrane degradation, fouling, scaling, and shortened service life.
- Energy-intensive treatment trains such as evaporation or distillation.
An integrated membrane-and-module platform.
The HTRO platform is based on advanced thin-film composite reverse osmosis membrane technology designed for enhanced thermal stability, mechanical durability, water permeability, and contaminant rejection.
Spiral-Wound Module Fabrication Line
Built for practical deployment
GREENVI™ is developing compatible spiral-wound modules using thermally stable materials, adhesives, spacers, and sealing components suitable for high-temperature operation. The goal is a complete membrane and module system capable of withstanding thermal and mechanical stress.
