A series of adsorption experiments was conducted in order to assess the ability of three mulches to remove several of the heavy metal ions typically encountered in urban runoff. Three types of mulch, cypress bark (C), hardwood bark (H), and pine bark nugget (P), were selected as potential sorbents to capture heavy metals in urban runoff. The hardwood bark (H) mulch had the best physicochemical properties...
In this study, a mathematical model has been developed for the submerged membrane bioreactor (SMBR) combining the activated sludge model No.1 (ASM1) with a membrane fouling model. The ASM1 was modified to take account into biological characteristics of the SMBR process, and the resistance-in-series model was integrated into the modified ASM1 to describe membrane fouling. Four additional 1st-order...
