Abstract The use of upflow sludge blanket filtration (USBF) covers the whole spectrum of chemical and biological treatment of water using the agglomeration processes for transformation of colloidal and dissolved impurities in water into separable floc suspension. The technical applications of USBF involve a wide range of treatment of underground and surface water for communal and industrial use, and municipal, industrial, and agricultural biological wastewater treatment.The fluidized bed filtration is a complex phenomenon based on a number of principles. In addition to the exposition of those principles, this chapter discusses the principles of integrated USBF reactor's design, gives examples of USB technology implementation, explains the advanced wastewater treatment systems and works out a design example of advanced treatment systems, the upgrading of a classical municipal WWTP.Key WordsReactor designupflow sludge blanket filtrationUSBF technologywastewater treatment
