  • Hg removal and the effects of coexisting metals in forward osmosis and membrane distillation

    In this study, we investigate the rejection of Hg, Cd, and Pb and the effect of coexisting metals on Hg removal through forward osmosis (FO) and membrane distillation (MD) in order to establish a more effective water treatment process. The results of our laboratory experiment indicate that more than 97% of the rejection for each metal is achieved through the FO system, and this rejection is ...

  • Antifreeze Liquid for Windshields Washer

    In cold weather, car windscreen washer system requires the use of special liquids. The thing is that if you pour plain water, it will simply freeze. Ice crystals cause damage to washer system; besides, water will form frozen drops and stains on the glass, which will significantly worsen visibility for the driver. When should one use non-freezing liquid? In such conditions non-freezing liquid for ...

  • Optimization of permeate flux produced by solar energy driven membrane distillation process using central composite design approach

    Membrane distillation (MD) is considered as a relatively high-energy requirement. To overcome this drawback, it is recommended to couple the MD process with solar energy as the renewable energy source in order to provide heat energy required to optimize its performance to produce permeate flux. In the present work, an original solar energy driven direct contact membrane distillation (DCMD) ...

  • The role of soil moisture accounting in estimation of soil evaporation and transpiration

    In this study, we explore how the differences in soil moisture accounting affect the estimation of actual soil evaporation (E) and transpiration (T). The main objective is, therefore, a comparative assessment of a vapor flux estimation method which has explicit soil moisture accounting, against a vapor flux estimation method that uses satellite observed soil moisture data. ...
