WebThe DO200A offers fast DO response times in wastewater, surface water and aquaculture applications. This process is sped up by aeration. Indigo carmine reacts with the DO in the water producing a blue color proportional to the DO concentration. Dissolved oxygen is a measure of the amount of gaseous oxygen contained in water. Low levels of DO can cause an increase in ferrous iron concentration resulting in discoloration at the tap when water is aerated. LDO allows the systems to automatically control the aeration system to a certain DO set pointallowing the aeration system to respond to the loading in real time, saving 30 to 60% in energy costs. In aquariums and on fish farms a minimum DO level of 4.5 mg/L is necessary to support fish life. Regardless of the quality of the Columbus wastewater effluent, the minimum 24-hour average dissolved-oxygen concentration of at least 5 milligrams per liter, the State's water-quality standard for streams, would not be met.

Oxygen enters a stream mainly from the atmosphere and, in areas where groundwater discharge into streams is a large portion of streamflow, from groundwater discharge. Microbial decomposition is an important contributor to nutrient recycling. DO levels need to be replenished in effluent water leaving the facility in order to meet minimum DO level requirements to protect ecosystems and to comply with regulatory discharge permits. This relationship also explains the potential for "supersaturation" of waters below the thermocline - at greater hydrostatic pressures, water can hold more dissolved oxygen without it escaping.
