Wastewater biological treatment attached growth

The well-known aerobic downflow process is a trickled bed filter. Attached growth is used in the biological treatment of wastewater. Air passes through the bed while the liquid is forced to down by gravity. Figure 13.2 shows the liquid gas system for the mass transfer... [Pg.325]

Since high levels of heavy metals can inhibit the growth of microorganisms when they are used as biosorbent materials, in some cases direct biological treatment is not usually feasible, and suitable pre-treatment is required. Ultrafiltration (UF) has been applied for the treatment of high metal-contaminated wastewater before of the biosorption process (Katsou et al, 2012 Malamis et al, 2010). UF membrane modules are able to retain suspended sohds (SS) and the majority of colloidal matter. Thus, metal forms attached to SS are effectivelyremovedbytheUF membranes. [Pg.178]
