OWML: Current Projects
Membrane Bioreactor Versus Conventional Wastewater Disinfection Study |
|
Membrane bioreactors (MBRs) are a relatively new wastewater treatment technology in which the conventional secondary treatment or secondary with tertiary treatment processes are replaced by a membrane separation process. Although there is adequate information on the reduction of bacteria and protozoa concentrations through MBR
processes, especially in drinking waters, manufacturers report
variable success in reducing concentrations of viruses.

IMS/ATP rapid method optimization;
QPCR for E. coli and enteric viruses |
|
E. coli
analysis by real-time PCR (QPCR) and IMS/ATP rapid method are new
methods that have shown promise by the USGS and other agencies. E.
coli by QPCR is a method that needs to be explored as a new
capability for the OWML. E. coli by IMS/ATP rapid method is
currently being used for two projects by the OWML; however, it has
been determined that some optimization should be done to

Testing of analytical methods for
pathogens in finished drinking-water supplies |
|
Certain microbiological
pathogens are considered potential biological warfare agents and
cause homeland security concerns, especially for drinking-water
supplies. Traditional cultural and microscopic methods allow
detection of these pathogens; however, the methods take days before
any confirmatory answer is available. A quantitative polymerase
chain reaction
