This slide presentation outlines information on Haloacetic Acid removal using granular activated carbon, focusing on biofilm community structure. Three approaches are outlined:
adsorption, isotherm tests for carbon
adsorption capacity;
biofilm development, polymerase chain reaction (PCR) amplification of
intergenic spacer region; and,
mature biofilm, HAA degradation by
biological active carbon (BAC). Conclusions included: the intergenic spacer region analysis revealed
that the microbial diversity diminished and
stabilized along the filter run;
bacterial community diversity may be correlated
with HAA degradation;
hydrogenophaga palleronii (PCR identified
bacterium) did not degrade any HAAs tested; and,
isolate MC5 from enrichment cultures expressed
higher degradation rates and affinity to ClAA
than to Cl2AA. Includes figures.
