General information
2.1 Safety information
Please read this entire manual before unpacking, setting up, or operating this
equipment. Pay attention to all danger and caution statements. Failure to do so
could result in serious injury to the operator or damage to the equipment.
To prevent any impairment of the instrument's safety features, it must not be used
or installed in any manner other than that specified in this manual.
DANGER
Do not use the probe in hazardous area.

2.2 Applications
UVAS plus sc:
immersed directly in the medium, without pumping or preparation of a sample, the
sensor measures the content of dissolved organic compounds in activated sludge
tanks in municipal sewage treatment plants, surface water, untreated water and
treated drinking water. The system can also be used for checking the outlet of
waste water treatment plants.

Bypass accessories for UVAS plus sc:
the through-flow variant of the high-precision UVAS plus sc sensor is used
wherever direct measurement in the medium is not possible for constructionrelated reasons or the medium load makes it necessary to measure a filtered
sample (very high TS contents, sewage treatment plant inlet, waste dump
seepage,...).
NOTICE
Any use other than use in accordance with requirements defined in the user manual
leads to the loss of the warranty claims and can lead to personal injury and property
damage, for which the manufacturer assumes no liability.

SAC

TOC
Organic compounds dissolved in water in general absorb UV light, for this reason
the measurement of UV absorption represents an independent total parameter for
dissolved organic substance water load. In drinking water treatment this method
of determination of the quality of water without chemicals using laboratory
photometers and filtered samples has a long tradition.
DIN 38402 C2 stipulates for the measurement of the UV absorption, the
measuring wavelength of 254 nm and characterises the measured value for a
filtered sample as a spectral absorption coefficient at 254 nm (SAC254 for short),
which is to be converted to extinctions per metre. In this way straightforward
comparability of the measured results from photometers with different cuvette
intensities is achieved and the units 1/m or m–1 are obtained.
The UVAS immersed probe comprises a multiple beam absorption photometer
with effective turbidity compensation. The related controller controls the process
of the measurement using a flash lamp photometer, the mechanical cleaning of
the measuring window by a wiper, and also displays the measured values as
SAC254 in 1/m.
For other total parameters such as COD or TOC etc. there is a correlation for the
SAC254 of the same quality as, e.g., between COD and TOC. Very high
8
General information
availability of measured values, minimum investment, minimum effort for
installation and maintenance or upkeep are therefore often key reasons for the
decision in favour of the UVAS sensor if an online measurement is to be used for
a total parameter.
For media containing solids, the SAC measurement with UVAS should always be
supplemented with a solids or turbidity measurement (SOLITAX sc,
ULTRATURB sc).
The maintenance effort for the user is minimal and is limited to a straightforward
inspection that, depending on the medium, is due at the most weekly.

4.5 Calibration
The instrument has been carefully calibrated before delivery and the calibration
will not change for a long time.
It is recommended to regularly check the calibration (4.5.1 Verifying, page 22)
with a test glass. In case of large deviations, first a zero point calibration (4.5.2
Zero point calibration, page 22) must be performed to compensate for a zero point
offset, before the gradient is allowed to be changed with the 1 point calibration
(4.5.3 1 point calibration, page 23).
During the calibration only mE values are displayed. The setpoint adjustment is
also referred to the unit of measure mE. This setpoint is noted on the filter for the
verification, liquid standards must be measured with an external spectral
photometer and the measured values converted to the sensor layer thickness.

Operation
4.7 Conversion into other total parameters
SAC 254 is an independent total parameter for the dissolved organic content of
water and evaluates, like all other total parameters, only ever a specific fraction of
the water load. Despite their major similarities, total parameters can only be
converted from one to another within certain limits. However, if a correlation is
found between SAC 254 and another total parameter, the converted measured
values from UVAS probes can be displayed as mg/L TOCuv, CSBuv etc.
To determine the correlation, first a measurement of the SAC curve should be
made over a few days. Only a regular daily curve with pronounced low and high
load times such as with municipal waste water offers a good basis for satisfactory
conversion.
At the times of day found for low and high load
•
A representative sample should be taken at the UVAS probe location,
•
The related SAC value should be read and
•
A laboratory measurement of the parameter to be correlated should be
made.
Example:
Sample 1 SAC 254: 105 1/m ; TOC: 150 mg/L:
Sample 2 SAC 254: 35 1/m ; TOC: 38 mg/L:

Maintenance
CAUTION
Pinch Hazard. Only qualified personnel should conduct the tasks described in this
section of the manual.
The cleanliness of the two measuring windows in the sensor measuring path is
crucial for correct measured results!
The measuring windows should be checked weekly for soiling and the wiper
profile checked for wear.
NOTICE
The seals must be replaced annually by the manufacturer's customer service! If the
seals are not changed regularly, water may enter the probe head and seriously damage
the instrument!
