2. Oxygen saturation - Wikipedia

   en.wikipedia.org/wiki/Oxygen_saturation

   It can be measured with a dissolved oxygen probe such as an oxygen sensor or an optode in liquid media, usually water. [1] The standard unit of oxygen saturation is percent (%). Oxygen saturation can be measured regionally and noninvasively. Arterial oxygen saturation (SaO 2) is commonly measured using pulse oximetry.

   English: Dissolved oxygen sensor in a sewer treatment plant. The sensor continuously monitor the dissolved oxygen level. The sensor continuously monitor the dissolved oxygen level. It is used as a feedback loop to control the blowers in an aeration system.

4. Oxygen sensor - Wikipedia

   en.wikipedia.org/wiki/Oxygen_sensor

   The Clark-type electrode is the most used oxygen sensor for measuring oxygen dissolved in a liquid. The basic principle is that there is a cathode and an anode submersed in an electrolyte. Oxygen enters the sensor through a permeable membrane by diffusion and is reduced at the cathode, creating a measurable electric current.

   They produced their first environmental monitoring instrument, a dissolved oxygen sensor, in 1992. They then developed instrumentation for conductivity measurement of ultrapure water in 1996, and the first accurate commercial fiber-optic based CO 2 measurement system, in 1998.

6. Winkler titration - Wikipedia

   en.wikipedia.org/wiki/Winkler_titration

   The Winkler test is used to determine the concentration of dissolved oxygen in water samples. Dissolved oxygen (D.O.) is widely used in water quality studies and routine operation of water reclamation facilities to analyze its level of oxygen saturation. In the test, an excess of manganese(II) salt, iodide (I −) and hydroxide (OH −) ions ...

7. Water aeration - Wikipedia

   en.wikipedia.org/wiki/Water_aeration

   Fountains aerate water by spraying it into the air. Water aeration is the process of increasing or maintaining the oxygen saturation of water in both natural and artificial environments. Aeration techniques are commonly used in pond, lake, and reservoir management to address low oxygen levels or algal blooms.
