This study involves the development of a biofilm
reactor that supports growth of a deep biofilm on a gas
permeable membrane. The reactor solution is not aerated,
and oxygen is supplied through the membrane. The reactor
is termed a substratum-aerated-biofilm reactor or SAB.
With adequate concentrations of electron-donors and
electron-acceptors,...
Chlorinated low molecular weight solvents have been discovered in a number of the nation's groundwater supplies. Remediation of these aquifers will require some form of treatment. Presently, the dominant treatment method is air stripping which results in transfer of the solvent from the aqueous phase into the atmosphere. Biodegradation is...
