- Method of Making Nanofiltration (NF) & Reverse Osmosis (RO)Membranes
Technology Overview
This invention boosts nanofiltration and reverse osmosis membranes, increasing water permeability by 2–5 times with stable additives for uniform, scalable production.
Industrial & Environmental Water Treatment Technology
-
Higher Permeability for Shipboard Desalination:
Increases thin-film composite membrane permeability by 2–5× without sacrificing salt rejection, enabling faster, more efficient freshwater production onboard vessels and offshore platforms.
-
Retrofittable with Existing RO/NF Systems:
Enhances membrane performance without major infrastructure changes, allowing cost-effective upgrades with minimal downtime.
-
Improved Energy Efficiency:
Higher flux at comparable rejection reduces energy per unit of treated water — critical for power-constrained ships and offshore facilities.
-
Versatile Maritime Water Treatment:
Applicable to both RO and nanofiltration for seawater desalination, ballast and greywater treatment, and selective ion removal.
-
Supports Sustainability & Compliance:
Enables higher throughput and efficient water recovery, helping meet tightening environmental and discharge standards.
Maritime Use Cases

This technology improves membrane water permeability, enabling more efficient and energy-saving desalination processes to supply freshwater for long-haul maritime operations. By increasing filtration performance and reducing fouling, it helps lower maintenance requirements while supporting reliable onboard water production.

The membrane system can also enhance ballast water treatment by improving filtration efficiency, helping vessels meet IMO Ballast Water Management standards. In offshore environments, the technology supports more efficient water recycling, reducing the need for frequent freshwater supply deliveries and improving the sustainability of offshore operations.
