Project Overview
Following the foundational research on bacterial biofilm adhesion (TRL 1-3), this second phase, focused on applying biofilm de-adhesion from various nanofiltration (NF) membranes (TRL 4-6) with different surface roughness, material compositions, and coatings. The project was conducted under Professor Eoin Casey’s group at University College Dublin in collaboration with the Irish water tech startup OxyMem and became part of a €2 million ERC-funded initiative.
This research used advanced microscopy and nanomechanical testing techniques to analyze biofilm behavior on NF membranes, specifically in drinking water purification systems. The study was designed to bridge the gap between academic research and industry needs, providing scientific validation for biofilm-resistant membrane development in commercial water treatment applications.
1. Business Opportunity
Market Need & Pain Points
Biofilm fouling on NF membranes is a critical issue in water treatment plants, industrial filtration systems, and desalination units, reducing operational efficiency and increasing maintenance costs. Existing solutions rely heavily on chemical cleaning and operational adjustments, which have environmental drawbacks and limited long-term effectiveness. There is a growing demand for membranes engineered to resist biofilm formation, reducing reliance on chemical treatments and extending membrane lifespan.
The lack of scientific data on biofilm adhesion mechanisms specific to NF membranes has hindered the ability of membrane manufacturers to develop optimized, antifouling solutions. This research aimed to fill that gap by providing detailed adhesion force data and material-specific biofilm resistance analysis, enabling manufacturers to design membranes with improved performance in real-world water treatment systems.
Target Industry & Market Size
By 2015, the global NF membrane market was valued at $1.5 billion, with demand rising due to increasing needs for high-performance filtration in municipal water treatment, pharmaceuticals, and industrial processing. The market was projected to grow at a CAGR of 9.2%, driven by tightening water quality regulations and the need for cost-effective biofilm control strategies.
The research findings had direct relevance for water technology companies, membrane manufacturers, and industrial filtration system providers looking to enhance membrane performance and longevity. By integrating biofilm-resistant designs into NF membranes, companies could significantly reduce operational costs and improve system reliability, making them more competitive in the growing water purification sector.
2. Technology & Competitive Advantage
Innovation Overview
Operating at Technology Readiness Level (TRL) 3-6, this study focused on the real-world application of bacterial biofilm adhesion and de-adhesion research to industrial NF membranes. Using SEM, AFM, and micro-mechanical testing, the project systematically evaluated:
- How biofilm adhesion varies across NF membranes with different surface roughness and material properties.
- The effectiveness of various polymeric coatings in reducing bacterial attachment and improving antifouling properties.
- The role of hydrophilic vs. hydrophobic membrane surfaces in bacterial adhesion and de-adhesion behavior.
These insights allowed for a data-driven approach to membrane material selection, ensuring that future NF membranes could be designed with optimized biofilm resistance properties.
Key Differentiators
Traditional antifouling strategies rely on post-fouling treatments, such as biocide applications and mechanical cleaning, which lead to increased operational costs and potential membrane damage. This research provided an alternative strategy by helping membrane manufacturers engineer biofilm-resistant surfaces from the start, reducing reliance on reactive cleaning methods.
Additionally, by leveraging nanomechanical adhesion force analysis, the study provided quantifiable performance data on how specific material properties influenced biofilm attachment, allowing direct optimization of membrane coatings. This scientific validation was critical for gaining industry adoption and improving NF membrane product development.
