As
with any biological system, activated sludge
plants are fairly sensitive to any changes
in the influent or to modifications in operating
conditions. Many plant operating problems
can anticpated as a result of microscopic
analysis before any obvious changes in physical
characteristics are evident. Therefore,
microscopic examination can be a vital tool
to help identify problems before consent
limits are approached or exceeded.
Certain
characteristics identified under the microscope
can give some indication of the problems
within the plant.
- Abundance
and species of filamentous bacteria
- Protozoal
ecology
- Size
and shape of sludge flocs
The
microscopic appearance of activated sludge
can be a valuable troubleshooting tool,
giving important clues about what may have
gone wrong. Regular microscopic analysis
can also be predictive. The skill in examining
activated sludge, use of a microscope and
identification of these parameters can be
taught to most people, but it requires practice
and patience. Aqua Enviro can offer expert
guidance with onsite training by recognised
experts.
Aqua
Enviro offer a laboratory based examination
service to support and validate on site
examination. This valuable resource provides
reassurance that the on-site results are
meaningful. We offer detailed descriptions
of the flocs, bulk liquid, protozoa as well
as filament identification, which is very
difficult for the non-microbiologist to
carry out. This service is offered with
a 24-hour turnaround providing a clear report
confirming the filament species present,
digital photomicrographs as standard, and
the operational options for eliminating
the troublesome filaments. A personalised
monthly monitoring and analysis service
can be provided with feedback on recommended
modifications for plant optimisation and
management, for further information on this
please see plant management.
