TI  - Comparison of polysulfone and ceramic membranes for the separation of phenol in 
      micellar-enhanced ultrafiltration.
PG  - 157-63
AB  - Micellar-enhanced ultrafiltration (MEUF) of phenol and a cationic surfactant, 
      cetylpyridinium chloride (CPC), is studied using two polysulfone membranes of 5- 
      and 50-kDa molecular weight cutoff (MWCO) and two ceramic membranes of 15- and 
      50-kDa MWCO. Filtrations are run under laminar cross-flow and steady-state 
      conditions. The effect of operation variables (pressure and retentate flux) and 
      membrane properties (nature and MWCO) on permeate flux, surfactant, and phenol 
      rejections is analyzed. The permeate flux depends, among other variables, on the 
      fouling favored by membrane-micelle interactions, which are strongest in the 
      50-kDa MWCO ceramic membrane. On the other hand, surfactant rejection is mainly 
      determined by the pore size and influenced by the pressure for both 50-kDa MWCO 
      membranes. An equilibrium distribution constant, K(s), of phenol between 
      surfactant micelles and water is calculated. Its value is not significantly 
      affected by operation conditions and membrane type. K(s) is also approximately 
      20% lower than the value determined in a previous work with batch dead-end 
      ultrafiltration.
