“…The BDST model has been widely applied in the literature to predict the performance of fixed-bed adsorbers for the removal of heavy metals [27, 29, 30] such as arsenic, lead, nickel, manganese, iron, cadmium, and copper, and for the removal of acid & base dyes from water [28, 31] . However, some studies have applied the BDST model for organics removal from water [25, 26, 32-34] .…”

Methyl tertiary butyl ether (MTBE) has been shown to be readily removed from water with powdered zeolites, but the passage of water through fixed beds of very small powdered zeolites produces high friction losses not encountered in flow through larger sized granular materials. In this study, equilibrium and kinetic adsorption of MTBE onto granular zeolites, a coconut shell granular activated carbon (CS-1240), and a commercial carbon adsorbent (CCA) sample was evaluated. In addition, the effect of natural organic matter (NOM) on MTBE adsorption was evaluated. Batch adsorption experiments determined that ZSM-5 was the most effective granular zeolite for MTBE adsorption. Further equilibrium and kinetic experiments verified that granular ZSM-5 is superior to CS-1240 and CCA in removing MTBE from water. No competitive-adsorption effects between NOM and MTBE were observed for adsorption to granular ZSM-5 or CS-1240, however there was competition between NOM and MTBE for adsorption onto the CCA granules. Fixed-bed adsorption experiments for longer run times were performed using granular ZSM-5. The bed depth service time model (BDST) was used to analyze the breakthrough data.

“…TOC analysis is relatively easy, incorporating as it does all organic compounds and identifying relationships between these compounds and their treatability. DOM in natural waters significantly affects a number of aspects of water treatment, including the performance of the sequential unit processes: oxidation, coagulation, adsorption, and biodegradation, as well as source-related and seasonal causes [74,75].…”

“…Granular activated carbon (GAC) is a very effective adsorbent for NOM and TOC removal. The application of GAC for the removal of TOC has been used in the drinking water treatment industry for over two decades and has been recognized as one of the more optimal treatment technologies currently available (47).…”
