Other than data on the targeted oxidized compounds
nitrate and perchlorate, there is limited
information on how water quality parameters are
affected by membrane biofilm reactor (MBfR) treatment.
In order to assess challenges for MBfR field
application, the authors investigated the nontargeted
oxidized compounds sulfate and chlorate, the hydrogen
(H2) concentration in the effluent, possible undesired
reduction products when H2 is an electron
donor, changes in dissolved organic carbon and biodegradable
dissolved organic carbon, and the interactions
among pH, alkalinity, hardness, and calcium
carbonate precipitation. Results indicated that either
these parameters presented no problems or problems
could be easily prevented.
Removal of oxidized contaminants, particularly
nitrate and perchlorate, is one of the industry's
biggest emerging challenges. Biological reduction
using an MBfR offers a simple means of reliably and
cost-effectively achieving this goal. This study demonstrated
that water providers should be able to
apply MBfR treatment for removing oxidized contaminants
without introducing other water quality
problems. Includes 11 references, table, figures.
