Researchers at KAUST have developed a new polymer membrane for desalination that operates at ambient temperature and pressure. The membrane achieves high salt rejection with lower energy demand compared to conventional methods. It is currently being tested at pilot scale at KAUST. Why it matters: This technology could improve water sustainability and reduce energy consumption in desalination, addressing critical water challenges in arid regions like Saudi Arabia.
KAUST researchers have developed an ultrathin polymer-based membrane for water desalination with high water flux and salt rejection. The membrane utilizes two-dimensional porous carbonaceous materials with subnanometer-sized molecular transport channels. The membrane outperformed existing desalination systems using carbon nanotubes and graphene in forward and reverse osmosis. Why it matters: This innovation offers a promising alternative for efficient and cost-effective desalination, addressing critical water scarcity challenges in the region and beyond.
KAUST alumna Mona AlSaydlani (M.S. '13) is a founding class member who researched water desalination techniques under Professor Ingo Pinnau. She now works as a lead engineer in business communications at the Dow Middle East Innovation Center (MEIC) located on the KAUST campus, focusing on media, stakeholder relations, sustainability, and R&D. AlSaydlani also designs roadmaps for Dow Business activities and supports the Women's Innovation Network (WIN) at Dow Saudi Arabia. Why it matters: This highlights the career paths and contributions of KAUST alumni in industry, particularly in linking academic research with industrial applications and supporting women in STEM.
KAUST research scientist Muhammad Wakil Shahzad won the 'best presenter' award at the 2019 Global Summit and Expo on Power & Energy Engineering in Dubai. His presentation focused on the energy efficiency of seawater desalination processes. Shahzad's research at KAUST's Water Desalination and Reuse Center aims to improve desalination methods and develop water reclamation strategies. Why it matters: This award highlights KAUST's contributions to innovative desalination technologies, which are crucial for addressing water scarcity in the Gulf region and drought-stricken areas globally.
KAUST researchers are developing new solar desalination methods to increase efficiency and minimize heat losses, building on techniques dating back to Arab alchemists. KAUST Associate Professor Peng Wang and his team at the Water Desalination and Reuse Center are developing an innovative system that more efficiently vaporizes water using interfacial heating. The design uses a photothermal material to capture the entire spectrum of sunlight and convert it into heat with nearly 100% efficiency. Why it matters: This research could provide more sustainable and efficient methods for producing fresh water in arid regions like the Middle East.
