New Technology Offers Cost-effective Solution for Seawater Desalination
Researchers at the University of Michigan and Rice University have developed an innovative technology that could revolutionize the desalination process by efficiently removing boron from seawater. This advancement addresses a significant challenge, as boron can become a toxic contaminant in drinking water when conventional salt-removing filters fail to eliminate it.
The newly designed carbon cloth electrodes function by splitting water into hydroxide ions, which bind to boron. This enables the toxic element to adhere to positive electrodes, thus ensuring safer drinking water production. According to Weiyi Pan, a co-author of the study, this technology not only reduces the need for additional chemicals but also enhances environmental sustainability by cutting costs by up to 15%, equating to approximately 20 cents per cubic meter of treated water.
Currently, seawater desalination is a crucial resource management strategy as global freshwater supplies are projected to meet only 40% of demand by 2030. By increasing efficiency and reducing expenses, this new approach may encourage wider adoption of desalination technologies, potentially saving large facilities millions of dollars annually.
The findings were published in the journal Nature Water, highlighting the importance of developing sustainable water solutions in the face of a growing global water crisis.
