  • How to remove MTBE from water?
  • Adsorption, mainly utilizing granular activated carbon as adsorbent, is a commonly used method for MTBE removal from water. The main advantage of this process is the absence of by-products after water treatment and the drawback is that MTBE is just moved from one phase to another leading to contamination of adsorbent ( Rossner and Knappe, 2008 ).
  • Can air stripping remove MTBE from groundwater?
  • Formation and removal of tert-butyl formate (TBF) and tert-butyl alcohol (TBA) concurrent with MTBE removal in site A water (top) and diluted (1:4) site C water (bottom). 4. Conclusions This study has shown that air stripping, carbon adsorption, and advanced oxidation can each be effective at removing MTBE from a variety of groundwaters.
  • What is the removal rate of MTBE from groundwater?
  • Removal rate of MTBE from water was reported to be 88–93%, while for TCE and benzene it was 99%. Desorption of MTBE, TCE and benzene was 10%, 0.4% and 1%, respectively. 3. Air stripping Air stripping is a well known and established process for volatile organic compound removal from groundwater.
  • Does liquid activated carbon (LAC-Fe) improve MTBE adsorption efficiency?
  • Results of the study revealed that mixing of liquid activated carbon or LAC-Fe on subsurface materials had not improved the removal efficiency of MTBE. At the same time, it showed a slight improvement in the adsorption efficiency of benzene and toluene.
