      报告人:Dr. Boris Liberman, IDE Technologies Ltd (以色列脱盐工程技术有限公司). 

      报告题目:Cutting-edge Technology on Seawater Reverse Osmosis (SWRO) and New Development 

      报告时间:201443日(星期四)10:00-12:00 

      报告地点:过程大厦308会议室 

      主办:人事教育处、综合办公室、生化工程介质与设备创新团队 

      报告摘要: 

    Pressure retarded osmosis (PRO) can be implemented on a number of water types, using different technologies and achieving various power outcomes. This talk presents the three most practical options: 

    •   Option 1 - Seawater with river water, driving force 25 bar, power output 5-10 watt/m2 
    •   Option 2 - SWRO brine with wastewater, driving force 50 bar, power output 10-20 watt/m2 
    •   Option 3 - Dead Sea or salt lake with river water, driving force 250 bar, power output 50-100 watt/m2 

      Each of the above options requires a different PRO technology.  

    •   Option 1 necessitates movement of huge water volumes with extremely low power losses. All water movement must be at seawater level. The pressure exchanger consumes 15 times less power than it does in RO technology. Pretreatment CAPEX and OPEX expenses are considerably less than those currently implemented by RO technology, while water quality has to be as good as that required from RO. 
    •   Option 2 is the most economical and ready to use. This option uses already filtrated and pressurized brine from an SWRO plant. The main obstacle to the implementation of this option is finding a wastewater source with no cost.  
    •   Option 3 implements natural exotic resources such as Dead Sea water with extremely high osmotic pressures. The PRO technology in this option requires membranes and pressure exchangers that are able to operate at extremely high pressures.
