Advances in membrane technology for the treatment and reuse of food processing wastewater

摘要: Publisher Summary The food processing industry generates a large volume of wastewater and amount solid waste that can induce environmental problems; this should thus be reduced treated. impurities classified by size are solutes (small molecules – acids, bases, salts macromolecules proteins, peptides, etc.); colloidal suspensions (referred to as pseudo-solutions these generally two-phase heterogeneous systems, less than 100 µm in size); particulate (suspended solids visible under microscope, for example, algae, bacteria, etc. and/or larger particles, such sludge particles). Practically all the existing membrane processes use beverage its treatment. classic applications technology treatment Microfiltration (MF), Ultrafiltration (UF), Nanofiltration (NF), Reverse Osmosis (RO). These filtration applied clarification, sterilization, concentration, decoloration, demineralization, product recovery, most recently introduced industrial Electrodialysis (ED), Pervaporation (PV), Membrane Contactors (MC), strippers/scrubbers, extractors, distillation, osmotic removal organic pollutants, Besides separation processes, differently configured Bioreactor (MBR) is widely process cleaning industry. This chapter briefly describes methods MBRs. It discusses important mass transfer rate equations characteristic fouling concentration polarization layer forming on surface membrane. also presents some
