Soluble Microbial Products and Suspended Solids influence in membrane fouling dynamics andinterest of punctual relaxation and/or backwashing

Abstract : To favour the control of membrane fouling on line by relaxation and backwash sequencing, twomajor fouling origins are considered: the former is due to retention of large particles on themembrane surface forming a growing deposit that can be controlled by tangential shear stresses,the second is due to the retention of the largest soluble polymers forming a thin layer on themembrane surface including pore blocking and inducing a progressive reduction of the depositporosity, the influence of this second fouling origin can only be reduced by backwashing. Asimple model was developed to represent (i) the accumulation of two types of compounds and itsconsequences and the evolution with time of the hydraulic resistance of the system and (ii) therole of relaxation and backwashing to reduce the fouling impact. Some simulations were presented according to the values of the three model parameters. Simulations were also comparedto experimental data obtained on biological suspensions.
