Biological Treatment:
Anaerobic Systems
What Is
Anaerobic Treatment?
Anaerobic treatment is a biological
process ideally suited for the pretreatment of high-strength
wastewaters that are typical of many industrial facilities. The
anaerobic process utilizes naturally-occurring bacteria to break
down biodegradable material in an industrial waste stream.
The anaerobic process is time-tested and
does not require the purchase of special bacteria or nutrients.
Because the bacteria are anaerobic they do not require oxygen
like the organisms in an aerobic process. Reactors are enclosed
or covered to prevent the introduction of air and the release of
odors.
Applications
Anaerobic treatment is ideal for
pretreatment, pretreatment prior to aerobic treatment, and
pretreatment of segregated waste streams.
-
Used for standalone pretreatment, an anaerobic
system can be used as the sole biological component of a
treatment system for wastewater discharged to a POTW.
-
Used prior to aerobic treatment, an anaerobic
system can be very effective and economical for removing high
concentrations of BOD and COD prior to final treatment by an
aerobic process.
-
Many industrial facilities have waste streams
that represent a fraction of the total flow, yet contribute a
majority of the pollutant load. These high-BOD waste streams can
be segregated for treatment by an anaerobic process prior to
combining with the total flow.
ETS anaerobic systems are very effective in
wastewater treatment at a variety of industrial facilities,
including:
， Bakeries
， Beverage production facilities
， Breweries and Wineries
， Chemical plants
， Dairies
， Food processing plants
， Meat and poultry processing plants
， Pharmaceutical plants
， Pulp and paper mills
， Rendering plants
， Textile mills |
