The unwanted dgradation, the necessity of frequent cleaning which eventually
would result in high treatment cost, and often process failure. Bacteria, fungi, and
eposition/growth of microorganisms on or within the membrane surface results in biofouling of the membrane. Generally, any fouling resulting from
microbial colonization and biofilm formation is considered biofouling. Very few organisms present in the feed water can lead to significant biofouling of the membrane. Even
membranes using pre-treated influent with substantial removal of microbe is susceptible to significant biofouling [14, 15].
