Dissolved Oxygen Test Kit.
(1) Dissolved Oxygen is one of the most important analyses in
determining the quality of natural waters.
The effect of oxidation
wastes on streams, the suitability of water for fish and other organ-
i s ms
and the progress of self-purification can all be measured or
estimated from the dissolved oxygen content.
In aerobic sewage
treatment units, the minimum objectionable odor potential, maximum
treatment efficiency, and stabilization of wastewater are dependent on
maintenance of adequate dissolved oxygen.
Frequent dissolved oxygen
measurement is essential for adequate process control.
