How dissolved oxygen enters water. Dissolved oxygen enters water through the air or as a plant byproduct. From the air, oxygen can slowly diffuse across the water’s surface from the surrounding atmosphere, or be mixed in quickly through aeration, whether natural or man-made 7.The aeration of water can be caused by wind (creating waves), rapids, waterfalls, ground water discharge or other

Water Dissolved Oxygen Urban Aqua Care

Dissolved Oxygen or DO is the free oxygen available in the atmosphere which dissolves in water. By-product of photosynthesis released during the day by aquatic plants. Photosynthesis can be summed up as: CO2 + H2O = CH2O+ O2. Glucose (CH2O) formed is used by the aquatic plant. The oxygen (O2) is released and dissolved in water.
