Frequently changes and expansion
in industry leads to new processing lines
being developed, which in turn results in
a new effluent streams. These new effluents
may contain unusual compounds or simply
result in a higher or more concentrated
flow and may require additional treatment
before discharge. Treatability studies are
also of use to businesses beginning to treat
their own waste for the first time, perhaps
as a result of increasing trade effluent
disposal costs. Aqua Enviro have technical
expertise in a selection of technologies
that can be trialled under differing operating
conditions to optimise the proposed treatment
system.
In the past, studies have
been undertaken for water companies and
industrial clients using technologies such
as traditional activated sludge, SBR (sequencing
batch reactors), MBR (membrane bioreactors),
RBC (rotating biological contactors) and
various anaerobic digesters. After initial
discussions to determine the approach or
technology that is expected to successfully
meet effluent quality requirement, a treatability
programme can be put together.
Studies can be tailored
to suit individual customer requirements
but are scheduled for a minimum of 4 weeks
to allow a biomass to develop and acclimatise
to the waste stream. Data concerning the
influent and effluent to the treatment system
is collected along with monitoring of the
biomass and gas production if required.
If constraints allow then the toxic or shock
loading will also be applied to allow recovery
characteristics to be determined. A report
is produced covering all the data and operational
parameters used; this outlines the treatment
options available and any areas of further
investigation that are necessary. Aqua Enviro
are then able to scale up the pilot study
and to work with process designers to determine
the optimum solution for difficult or inhibitory
wastes.
