Orbisphere K1x00 Sensors are maintenance-free, optical Luminescent Dissolved Oxygen Sensors designed for monitoring oxygen in power plants. For years, these aeration systems were controlled by manually changing the airflow set point, valve positions, or speed of the motor because membrane DO sensors were unreliable. 0000013383 00000 n 0000011785 00000 n 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. This is true of both atmospheric and hydrostatic pressures. $1,116.09 - $3,138.32CAD / Each. Dissolved oxygen (DO) is necessary to many forms of life including fish, invertebrates, bacteria, and plants. WebDissolved Oxygen Meter. Influent water entering a facility has a low DO concentration because it contains organics and microorganisms which consume oxygen (while feeding on the organics). 0000017481 00000 n Indigo carmine reacts with the DO in the water producing a blue color proportional to the DO concentration.

Add your reagents or accessories now to save time and money later! Wine Producers maintain low DO content to prevent oxidation, loss of aroma, discoloration, rapid aging and the growth of microorganisms. Meet your regulatory needs with technology that is ideal for a wide range of applications and advanced dissolved oxygen analysis in the lab. In aquariums and on fish farms a minimum DO level of 4.5 mg/L is necessary to support fish life. However, for packaging low DO levels are necessary to improve shelf-life and to stabilize taste/odor. Healthy waters that can support life must contain dissolved oxygen. Low levels of DO can cause an increase in ferrous iron concentration resulting in discoloration at the tap when water is aerated. Two bodies of water that are both 100% air-saturated do not necessarily have the same concentration of dissolved oxygen. %PDF-1.4 % WebThere are two types of DO sensorselectrochemical and optical. startxref Process ControlDO levels are critical to control biological treatment of wastewater as well as the biofiltration phase of drinking water production. EPA approved for drinking water and wastewater compliance reporting. Higher oxygen levels yield lower emission intensities, so the DO can be measured via the luminescence peak, decay rate, or the signal phase difference. If DO levels are too low, bacteria die and decomposition stops; if dissolved oxygen levels are too high, then 1. Compared to Gas saturation decreases by 10% per meter increase in depth due to hydrostatic pressure. 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. Balanced DO can improve the taste of drinking water. This means that if the concentration of dissolved oxygen is at 100% air saturation at the surface, it would only be at 70% air saturation three meters below the surface. WebPro1020 Dissolved Oxygen and pH or ORP Instrument Rugged and reliable, the YSI Pro1020 provides everything you need in a handheld water quality instrument for the Rapid movement from winds, waves, currents or mechanical aeration. Microbial decomposition is an important contributor to nutrient recycling. To ensure accuracy the electrodes require frequent calibration and water samples must be gently stirred. Web2.0 Selecting a Method to Measure Dissolved Oxygen The concentration of oxygen dissolved in water can be evaluated in different ways. Aeration control in wastewater treatment.

Measuring dissolved oxygen in water, and treatment to maintain proper dissolved oxygen levels, are crucial functions in a variety of water treatment applications. User-replaceable sensors and cables along with convenient calibration routine feature makes it extremely user friendly. 100% air saturation means that the water is holding as many dissolved gas molecules at it can in equilibrium. The blue color can then be visually compared to a chart or read with a colorimeter or spectrophotometer. The amount of neutralizing agent required to neutralize the acid with titration indicates how much DO was in the original water sample. Bottom feeders, crabs, oysters and worms need minimal amounts of oxygen (1-6 mg/L), while shallow water fish need higher levels (4-15 mg/L). 0000014303 00000 n These regulations ensure that effluent water does not deplete oxygen levels in receiving waterways. Figure 15 Dissolved oxygen meter 27 Figure 16 ORP meter These organisms use DO to decompose organic material at the bottom of a body of water. 0000011126 00000 n It comes with an all-weather case and a three year warranty and requires minimal maintenance.
