The amount of dissolved oxygen is a measure of the biological activity
of the water masses. Phytoplankton and macroalgae present in the water
mass produce oxygen by way of photosynthesis.
Dissolved Oxygen, usually abbreviated to simply 'D.O.', is widely
used in water quality studies and routine operation of water reclamation
facilities.
Tests, test kits, electronic and optical sensors can all be used
top determine the concentration of dissolved oxygen.
A site dedicated to the following questions:
What is Dissolved Oxygen?
Why do we measure Dissolved Oxygen?
How do we measure Dissolved Oxygen?
Intending to give background information and culminating in the provision
of information and guidance on best practice for measurement of Dissolved
Oxygen in clean and waste water.
Oxygen saturation or dissolved oxygen (DO) is a relative measure
of the amount of oxygen that is dissolved or carried in a given medium.
It can be measured with a dissolved oxygen probe such as an oxygen
sensor or an optode in liquid media, usually water.
