This powerpoint presentation begins by providing a brief overview of biological filtration (biofiltration), including basic aspects of biological processes and a physical concept of a biofilm system. The presentation covers modeling and a unifying concept, pharmaceuticals removal, and membrane pretreatment. The presentation summary includes: classical and newer objectives for biofiltration includeno design criteria and theneed for a practically based modelling approach; dimensionless contact time (X) useful unifyingparameter;simplification and extension of X possible; biofilters can remove certain pharmaceuticals and endocrine disrupting compounds; biofiltration as a pretreatment can reducemembrane fouling, althoughfurther development and experimental verificationnecessary; and,the Biofiltration Factor (BF) -- a (new) possiblepractically-oriented design parameter. Includes figures.
