In conjunction with the intuitive Field Data
Manager software (FDM), remote access
and further processing becomes very easy
to imple
ment.
Energy monitoring offers:
• optimised plant performance
• increased pump efficiency
• monitoring electricity generation
(where biogas is used)
• improved aeration performance
• customised KPIs.
All parameters in view Endress+Hauser
offers an elegant way to combine online
analytics and sampling in a single sys-
tem. The basis for this innovation is the
Liquiline CM44x multichannel transmitter,
which not only supplies the analytical sen-
sors, is also the core electronic component
of the CSF48 sampler series. A single
Liquiline transmitter can control sampling
programs as well as up to four additional
online parameters simultaneously.
The Liquistation CSF48 sampler can
be easily converted into a smart, reliable
measuring station by linking up to four
freely selectable analysis parameters.
Safe and cost-effective
aeration control
Using online analysis can improve per-
formance. The combination of oxygen,
ammoniumand nitratemeasurement with
load-dependent aeration control can help
operators to improve plant performance
through reducing emissions and improving
safety and energy efficiency.
Reliable removal of COD and nutrient
load is essential. This makes efficient
plant operation necessary in order to allow
oxygen input and non-aerated periods to
finalize the nitrogen removal through de-
nitrification. Monitoring the exact amount
of the aeration’s energy consumption is
critical to managing overall energy costs
effectively. Biological wastewater treat-
ment is a core process in any modern
sewage processing plant. It involves the
decomposition of organic loads and
nutrients that can cause eutrophication
in downstream water bodies. Aeration of
the aerobic treatment step is, however,
a major cost factor, with at least 50 % of
electrical energy being consumed here
alone.
It has already been proved by many
operators that a strategically implemented
aeration control system can significantly
improve both effluent discharge va
lues as
well as energy consumption.
Inmany places phosphate precipitation
is also necessary, but this also represents
a significant cost factor. Load-sensitive
phosphate precipitation is an effective
solution for cost-efficiency and safe phos-
phate discharge levels.
Liquiline Control CDC81
The Endress+Hauser load-sensitive con-
troller, Liquiline Control CDC81, using
ammonia
and nitrate levels in the process,
aims to achieve safe effluent levels as
first priority and also to reduce energy
consumption significantly. The controller
can be rapidly commissioned and supplies
identical HMIs for up to three biological
treatment zones. It provides real time
control, fieldbus communication, failure-
safe modes according to process impact,
data logging, event and alarmmessaging.
The Liquiline Control CDC81 is able to
control and optimise continuous aeration,
intermittent aeration as well as precipitant
dosing for phosphate removal,
Further support services
A 24/7 service helpline is there to support
you and give you required assistance in
order to minimise your downtime. This
can be telephonic assistance or on-site
diagnostics or repair. Engineering, com-
missioning, traceable calibrations, main-
tenance and expert product training are
also available
.
Only a clear picture and detailed knowl-
edge of the installed instrument base can
act as a solid foundation for a predictive
maintenance and optimising strategy
for your plant. Whether you need to find
information concerning spare parts, verify
software versions, trace instrument his-
tory records on the basis of key events or
view the plant database with its installed
instruments – the data must be up-to-date
and rapidly available.
