Over the past thirty years, biologically active filters (BAF) have been demonstrated as reliable and robust processes for wastewater treatment. These systems can be designed for carbon removal, nitrification or denitrification depending on process objectives. There are a number of configuration options with differences in media and the backwashing regime, and there are several manufacturers of each type of process equipment package. This paper is being submitted by the authors of the BAF section that was recently written for the new WEF Manual of Practice No. 8 and will cover process variations, equipment types and patent issues, and process and detailed design information for each type of BAF to assist the designer in making an independent assessment between types of BAF configurations.

“…Para reactores de lecho fijo, el aire se introduce hacia el material filtrante por medio de una malla que ayuda a que la distribución sea homogénea sobre la sección transversal del reactor. Conforme las burbujas de aire se desplazan a través del material filtrante, se unen rápidamente dando como resultado la formación de burbujas más grandes (Stenstrom et al 2008). En los reactores de biopelícula suspendida, el proceso de aireación por lo general es utilizado con un doble propósito, el de proveer oxígeno y además el adicionar energía para el mezclado.…”

“…Scholars at home and abroad have conducted extensive research on the mechanism of oxygen mass transfer. Yin, Hu, Zhuang, Stenstrom, and Wei − studied the effects of aeration volume, aeration density, aeration aperture, water depth, and aeration mode on oxygen mass transfer. Most of these studies were based on macroparameters and lack analyses on the micro-mechanism of oxygen mass transfer.…”

Improving the gas–liquid mass transfer efficiency in microporous aeration technology is the key to strengthening the restoration effect of black and odorous water bodies. However, the effect of bubble motion characteristics on oxygen mass transfer has not been systematically studied, which limits the efficient and economical application of microporous aeration remediation technology in black and odorous water. The influence under different aeration pipe lengths was analyzed for oxygen mass transfer and bubble movement in microporous aeration technology. The aeration pipe length (0.1–0.5 m) was positively correlated (R = 1.000, R = 0.997) with the number of bubbles and the specific surface area of bubbles and negatively correlated with the time-average velocity of bubbles and Sauter average diameter (R = −0.999, R = −0.997). Moreover, the increase in pipe length weakened the disturbance intensity of plume to water body. The results of oxygen mass transfer showed that the oxygen mass transfer coefficient (K L a) and oxygen utilization rate (E A) increased (K L a from 1.96 to 4.57 h–1, E A from 6.47 to 15.07%) with the increase of pipe length, which was significantly positively correlated (R = 0.985, R = 0.969) with the number of bubbles and bubble specific surface area (S b). This study provided theoretical parameters for the mechanism of oxygen mass transfer during microporous aeration.
