DESALINATION RESOURCES
-
Saudi Arabia, the United Arab Emirates, and neighboring countries in the Persian Gulf region use the fossil fuels under their desert lands not only to make money, but also to make drinking water. The petroleum they produce powers more than 400 desalination plants, which turn seawater into drinkable water.

People around the globe are trying to figure out how to save, conserve, and reuse water in a variety of ways, including reusing treated sewage wastewater and removing valuable salts from seawater. But for all the clean water they may produce, those processes leave behind a type of liquid called brine. I’m working on getting the water out of that potential source, too.

Researchers have developed polyimide-based membranes for membrane distillation (MD) that overcome three persistent issues in membranes for water treatment and gas separations: the need for pore-forming chemicals that prevent recycling, performance degradation due to pore wetting and fouling, and the inherent trade-off between high water flux and selectivity.

Small municipalities and industrial sites face constant pressure: deliver safe, stable water with limited resources and tight deadlines. Traditional on-site construction can stretch project schedules by months and introduce quality and cost risks. By shifting much of the fabrication off-site, these risks are dramatically reduced.

Researchers warn that California and other states affected by megadroughts — periods of drought lasting 20+ years — will have to accept this as the new normal. That means rethinking the water cycle and finding new, more sustainable water sources.

This article explores how IDE Technologies leveraged advanced in-house simulation capabilities to deliver a revised brine diffuser design, significantly improving both environmental outcomes and operational efficiency.

Read about a seawater desalination plant that presented with several performance issues and chose the HOD UV system to control biofouling on the RO membranes.
