Rapid Synthesis Of Dual-Layered Covalent Organic Framework Membranes Via Interfacial Polymerization With Enhanced Desalination Performance, Miguel Angel Jaimes

Theses and Dissertations

As a consequence of disrupting the water cycle via human interventions, such as climate change, humanity is facing global water crises. The water crises are wide ranging, but often associated with the deterioration of a local water cycle’s capacity to support a population. This capacity is reduced on a global scale through the atmosphere via climate change, but on a local scale, it can be reduced because of an over extraction of resources, alteration of ecosystems, and water pollution. The deployment of desalination plants is growing around the world. Reverse osmosis (RO) desalination is much more efficient than the thermal …


Organic Fouling Behavior And Mechanisms In Nanofiltration Membranes For Water Treatment Processing, Sydney Rose Morgan May 2023

Organic Fouling Behavior And Mechanisms In Nanofiltration Membranes For Water Treatment Processing, Sydney Rose Morgan

Theses and Dissertations

Nanofiltration membrane technology is an expanding topic of interest for use in water treatment processes, particularly in the elusive field of desalination. Desalination is becoming more and more necessary as climate-change related weather events like droughts, and populations in water scare areas both increase. Reverse osmosis membrane systems are a reliable, but costly method for removing salts from otherwise unusable saline water sources. One way to decrease the cost of these systems is by utilizing porous membranes, like ultrafiltration or nanofiltration membranes, for pretreatment. Additionally, nanofiltration has recently shown promise as an effective alternative to reverse osmosis in desalination systems.The …
