For aquaculture, if dissolved oxygen levels are too low, fish can suffocate and die as a result. In wastewater treatment plants, bacteria break down solids. If DO levels are too low, bacteria die and decomposition stops; if dissolved oxygen levels are too high, then energy is wasted through aeration of the water. In industrial applications, including boilers, supplemental water must have low DO levels to avoid corrosion and boiler fouling. Monitoring dissolved oxygen levels is critical to ensure process efficiency, as boiler fouling inhibits heat transfer. High dissolved oxygen levels in water can improve the taste of drinking water. However, high dissolved oxygen levels can increase corrosion in water pipes and transport lines.
Advantages of optical dissolved oxygen measurement
• Easy use, no membrane, no electrolyte.
• Long lifetime, maintenance free and less calibration.
• No flow dependency and fast response.
• Immune to electrical interference, no chemical interference.
