Continuous
rapid COD measurement is a procedure for quick analysis of
Chemical Oxygen Demand. In the PHOENIX-1010 analyser, this
procedure uses ozone for oxidation and thus operates with
one of the most powerful oxidizing agents available.
The analysis lag time between sample entering the intake and
data output is 3 to 15 minutes for a measurement range of
10 to 1500 mg/litre COD. The analyzer automatically
calibrates itself each day.

How
it works |
Dilution
water is enriched with ozone, and an ozone probe measures the
dissolved ozone level. Wastewater and ozone-enriched
dilution water then enter the reaction chamber where oxidation
occurs. A second ozone probe measures the residual
ozone level downstream from the reaction chamber. The
computer controls the mixing ratio of the pumps delivering wastewater
and dilution water so as to maintain a low, constant level of
ozone depletion in the reaction chamber, and a high, constant
level of residual ozone.
The mixing ratio of wastewater and dilution water is calibrated
and reported as COD.
For monitoring and control, PHOENIX-1010 is equipped with signal
outputs of 0-20 or 4-20 mA.
A built-in graphical display shows concentration data and other
important information, which are stored for the last 14 days.
A diskette drive provides long-term data storage.
