Optimizing Aeration Rate in Wastewater Treatment
OVERVIEW A significant portion of a wastewater treatment plant’s energy costs are due to aeration operations (~45-75% of the total energy). The required aeration rate of a biological treatment system is determined by three key parameters: incoming organic loading expressed in terms of COD or BOD, dissolved oxygen (DO) concentration maintained in the aeration tank, and the concentration of ...

How Do Dissolved Oxygen Probes Work?
How Do Dissolved Oxygen Probes Work? Dissolved oxygen probes deal with redox (redox) reactions, providing continuous and real-time measurements. Because they have an applied voltage, most DO probes require a "warm-up time" before use to polarize the electrodes before measuring DO in water. After connecting the dissolved oxygen probe to the meter, immerse the electrode sensor (dissolved oxygen ...

What is a portable dissolved oxygen detector
Introduction of Portable Dissolved Oxygens Detector: Dissolved oxygens analyzer is based on electrochemical principles. That is, on two different metal electrodes in the measured electrolyte solution containing oxygen. Oxidation-reduction reaction will occur, and the resulting diffusion current has a certain relationship with the oxygen concentration in the solution. It is an instrument for ...

Oxygen or Air-Feed Ozone Generators?
One of the first questions one is often faced with in designing an ozone system is whether the application requires concentrated oxygen or simply clean, dry air. I will explain why oxygen-feed ozone generators are the best choice for all industrial applications. It is very likely that your first online search for “ozone generators” will lead you to a series of air-feed generators. ...

How new technologies are shrinking wastewater’s hefty carbon footprint
Wastewater treatment plants are energy hogs. A 2013 study by the Electric Power Research Institute and Water Research Foundation reported that they consumed about 30 billion kilowatt-hours of electricity per year, or about 0.8 percent of the total electricity used in the United States. Wastewater treatment’s high energy footprint is ironic because the organic matter in wastewater contains ...

Salinity and miniDOT
The miniDOT and other optical dissolved oxygen sensors measure oxygen within a special plastic material that has the property of changing its fluorescence in response to the amount of oxygen present. Oxygen arrives within this material by diffusion from the surrounding environment, which is usually water. The miniDOT determines oxygen concentration in water dissolved oxygen by optically ...
