Development of Corrosion-Resistant Molecular Sieve Inclusion Nanocomposite (MoSIN) Membranes to Recover Water from Urine through Osmotic Processes

Project: Research project

Project Details

Description

We will incorporate high permeability waterselective Linde Type A (LTA) zeolite molecular sieve nanoparticles into corrosion resistant polymeric thin films (polyethylene terephthalate, high density polyethylene and polytetrafluoroethylene). We will investigate the fundamental chemistry and physics which influence the formation of our MoSIN membranes. In particular we will investigate how changes in fabrication parameters relate to the chemical structure, physical morphology, osmotic separation performance, and zeolite/polymer interface using a variety of characterization techniques. We will evaluate the long-term performance and corrosion resistance of the membranes in forward osmosis for dewatering of synthetic urine and pre-treated urine. We will evaluate the performance of the membranes in reverse osmosis for water recovery from concentrated urine brines.
