Mechanisms of permeate flux decay, solute rejection and concentration polarisation in crossflow filtration of a double chain ionic surfactant dispersion

摘要: Abstract The mechanism of crossflow membrane filtration an ionic double chain surfactant dispersion is evaluated by studying the deposition on and within its pores, together with transient behaviour permeate flux concentration. It shown that results in formation a secondary supported primary membrane. To large extent, controls rejection surfactant. formed surface penetrates into pores forming region high concentration which order magnitude higher than so-called (pseudo) gel structure membrane, from cold field emission scanning electron microscopy, differs expected basis phase at prevailing concentration, temperature pressure.
