Depending on the type of biofouling, regular membrane cleaning is required. Biofouling in membrane processes can be controlled or eliminated (Mansouri, Harrisson & Chen 2010) in the following three ways: 1. Continuous or intermittent biocide dosing 2. Optimizing the operating conditions, including pretreatment of feed to reduce nutrient availability and cleaning procedures 45 46 CHAPTER 2: Membrane Fouling and Strategies for Cleaning and Fouling Control 3. Developing new membrane or modifying the existing membranes to make them less prone to biofouling Biofouling can be controlled and reduced by chemical agents such as NaOH solutions, chelating or sequestration agents, surfactants, and disinfectants.
Internal pore blocking. 10 Schematic illustration of the possible fouling mechanisms of porous membranes. (a) Pore blocking. (b) Partial pore blocking. (c) Internal pore blocking. (d) Cake filtration with scanning electron microscopy (SEM) image of the surface-fouled membrane. j onto the pore walls. This restricts the flow of permeate and increases membrane resistance because of pore size reduction. Internal pore blocking is independent of feed velocity and mitigation by crossflow is almost absent.
