The purpose of this research was to determine the feasibility of using a
fluidized bed to improve the performance of reverse osmosis desalination. Five
different sizes of glass beads and six different kinds of membrances have been
tested. A glass bead size of approximately 0.0185 inch diameter appears best for
this fluidized bed in the brine flow velocity range between 0.57 and 0.97 cm/sec.
The significance of using the fluidized bed with these glass beads was to increase
the salt rejection and to increase the water flux by 21.7 to 35.8% for nylon
supported membranes. The most significant effects were on membranes where
concentration polarization was the greatest. - 中文關鍵字: --
