Project : Desalination of ultrahigh concentrated brine by nano-electrokinetics

  • Purpose

    ■ The objective of this research is to desalt a ultrahigh concentrated brine using a nanoelectrokinetic phenomena and to develop the technology for efficient removal of oil-contaminant from the source waste. ■ Detailed objective is as follows. - Develop a desalting technology of the ultrahigh concentrated brine (1~2M) at >90% removal efficiency and <10Wh/L power consumption using an ion concentration polarization phenomena. - Develop a separation technology of the oil-contaminated brine at >90% removal efficiency using an ion concentration polarization phenomena. - Develop a strategy to enhancing throughput over 100mL/min by the massive parallelization of an unit micro/nanofluidic system

  • Contents

    ■ ○ 1st year (‘13.09.~’14.08) develop low cost nanostructure fabrication method and design and analysis of unit desalting system - Controlling a nanostructure and surface potential to obtain ion concentration polarization at ultrahigh electrolyte concentration - Develop numerical model to simulate flow field/electric field/concentration field. - Design and optimization of the micro/nanostructure for >90% desalting efficiency ■ 2nd year (‘14.09.~’15.08) Optimizing a performance and throughtput of the desalter - Enhancing the power consumption and desalting efficiency - Removing micro oil-droplets from soruce waster - Increasing throughput using ultra-thin PDMS device

  • Expected Contribution

    ■ This novel nanotechnology can be used for resolving the environmental impact due to the ultrahigh concentrated brine coming with a shale gas extraction so that it can contribute to create new intellectual properties and niche markets. ■ This ion control mechanism can also be applied to high energy efficient membrane system for a novel water purification system or ion/protein preconcentration system
