UV absorption and color are two important parameters to secure quality of
the drinking water. UV absorption at 254 nm is indicating humic substances,
but detects in addition also other organic compounds as mineral oils,
aromats, solvents, etc. These substances normally have to be removed by
active carbon filtration. Generally, there is a fixed relation
between the UV absorption value and the DOC value. So continuous UV
absorption measurement may by used as a trend analysis of the DOC value,
e.g. for monitoring of raw water. Other typical applications are monitoring
of ozonization and activated carbon filtration to secure sufficient
disinfection or removal of organic substances. Furthermore, the color can be
measured at a wavelength of 436 nm. Continuous monitoring
of raw water and treated water allows optimized control of the treatment
process and results in a constant quality of the drinking water.
The new absorptiometer ColorPlus from SIGRIST is tailored to these
applications. Out of a modular system, a customer specific setup can be
realized, independent if in-line or bypass, color or UV absorption or a
combination of both, results in E/m or Hazen. The dual beam measuring method
and the integrated soiling compensation result in an excellent stability and
reliability of the measuring value. Options as turbidity compensation or measurement at up to three different
wavelengths complete the range of features.
