Objective:
This project aims to evaluate the promise of forward osmosis (FO) as a technology to enable direct potable reuse of water. FO is an emerging membrane technology platform that offers a low cost alternative to reverse osmosis (RO) as a means of recapturing wastewater for direct potable reuse. The barriers to direct potable reuse are great, mostly stemming from the lack of guaranteed removal of contaminants that can cause harm to humans even at low levels when exposure is chronic. The goal of this project is to develop new membranes that function in FO and test those membranes for removal of various contaminants.
Progress Summary:
We removed the polydopamine work from this project as one of its core features as we received funding to do more in depth and fundamental research on that work from another source. We have refocused our efforts on nanofiber materials and our work with 3M, though this year was largely spent writing. The overall goals of our project have not changed.
In year 3, we have continued development and characterization work of our membrane platforms, with a focus more on nanofiber materials and our collaboration with 3M.
- Platform 1: Nanofiber supported thin-film composite (TFC) membranes
- Platform 2: Polydopamine modified RO membranes for forward osmosis
- Platform 3: Nylon 6,6 supported TFC membrane
- Commercial membrane analysis
This report has demonstrated substantial progress on this Early Career award by many metrics. Significant progress is noted by not only the data, but also the presentations and overall dissemination of the work. We have laid the groundwork for substantial improvements in membrane performance on all of the platforms presented.
- Continued development of two new membrane platform designed for forward osmosis
- Two Ph.D. students trained, two more collaborators involved in the project
- Three undergraduate students trained
Future Activities:
The plan for the period starting 6/1/2014 and ending 5/31/2015 will be to focus on publishing. Furthermore, two of the graduate students supported by this grant will be defending their theses and the two undergraduate students supported will be graduating. We will, however, continue to develop the 3M and nanofiber platforms. Testing on actual wastewater may drop from the task list in the next year of the project. The work has shifted from direct application of wastewater treatment to more of a project focused on materials for FO membrane development.
- Optimization of membrane fabrication procedure for two platforms still being studied
- Elucidating transport mechanisms that could impact trace contaminant removal during wastewater reuse
- Publish and have two students defend their Ph.D. thesis
