“Why do we measure”<br />
oxi::lyser<br />
In drinking water applications the oxi::lyser is mainly used in<br />
early warning systems detecting problems in raw water quality:<br />
Reduced dissolved oxygen concentrations are often an indicator<br />
for harmful microbial or chemical contaminations of the water.<br />
Applied in natural waters or on fi sh farms the oxi::lyser <strong>can</strong><br />
detect anaerobic conditions, which are life threatening aquatic<br />
organisms, and thus it helps to prevent ecological as well as economic<br />
damage.<br />
pH::lyser<br />
<strong>Drinking</strong> water suppliers use the pH::lyser for the continuous process<br />
monitoring and control of chemical and physical treatment<br />
steps that are characterised by changes in pH, such as neutralisation,<br />
fl occulation or mixing of source waters. Furthermore, the<br />
pH::lyser is applied in early warning systems that monitor source<br />
water quality, both in ground and surface water.<br />
redo::lyser<br />
In drinking water treatment the redo::lyser is used mainly for<br />
process monitoring and control of treatment steps that result in<br />
signifi <strong>can</strong>t changes of the oxidation-reduction potential. Besides<br />
this, the redo::lyser is also applied as a component in early warning<br />
systems that monitor source water quality, both in ground and<br />
surface water.<br />
condu::lyser<br />
The condu::lyser is used for quality control in drinking water production<br />
and distribution. From source to tap the electrical conductivity<br />
of the drinking water is an essential parameter indicating<br />
the level of salts dissolved and thus the purity of the water.<br />
chlori::lyser<br />
When drinking water is disinfected through chlorination it is necessary<br />
to continuously control the actual free chlorine level. This<br />
is crucial in the fi rst place to ensure effi cient disinfection and secondly<br />
to prevent regrowth of microorganisms in the fi nished water.<br />
For these two tasks it is necessary to carefully process control the<br />
level of free chlorine, also in order to prevent the concentration of<br />
harmful disinfection byproducts that <strong>can</strong> be formed in the presence<br />
of chlorine.<br />
