Quarter-century relationship with St. Louis metro area treatment facility sees EDI deliver on the "Aeration for Life" promise Project Information Location: Duckett Creek, MO Project Type: Municipal Initial Installation: 1994 Upgrades: 2016, 2017, 2018 ...
Weekly composite samples were collected from both digesters; laboratory analysis focused on Oxygen Uptake Rate (OUR), Total Solids (TS), and Volatile Solids (VS). ...
Fermentation is a metabolic process in which microorganisms convert sugars into alcohol, acids, or gases without oxygen. Its most notable applications are in the food and beverage industry, including alcohol production, food preservation, and dairy manufacturing. However, it’s also essential in biofuel generation and industrial chemical manufacturing – typically via microbial ...
Summary This case study explores the efficacy of liquid and dry formulations of SmartBOD, compared to glycerin-based supplementation, in improving wastewater treatment processes. Focusing on aerobic activated sludge systems, the study aims to enhance microorganism health and effluent quality, with a particular emphasis on the newly introduced liquid formulation of SmartBOD. ...
How does aerobic treatment convert organic matter in industrial wastewater applications? This question may seem daunting to some. Truth is, when it comes to understanding the complex processes of wastewater treatment, many are left scratching their heads… This process involves biology and chemistry, two subjects that can make even the most dedicated environmental enthusiasts break out ...
Real-time gas analysis and reaction monitoring using mass spectrometry have opened up new possibilities in various industries, including biotech, petrochemical, environmental monitoring, and chemical synthesis. With the Hiden QGA system, researchers and professionals can benefit from the latest advancements in mass spectrometry for real-time multi-species quantitative gas ...
This data will also be helpful in processes where oxygen uptake and carbon production rates are vital for optimum yields. ...
In this study, we assessed the impacts of Qwik-Zyme P on poultry protein hydrolysis using oxygen uptake tests on samples collected from an anaerobic lagoon effluent, which enters into an aeration basin. An increase in oxygen uptake rate indicates improved aerobic degradation rates of the ...
Dairy wastewater frequently contains high levels of the complex protein casein, a milk solid with unique properties which make it difficult to breakdown. When enough casein is undegraded, it can lead to problems with poor settling, foaming, a cloudy effluent, and unnecessary plant expansion. Furthermore, undegraded casein does not release free amino acids, which aid in essential floc formation. ...
Unlike BOD reduction and nitrification, BNR processes require specific residual oxygen levels. This operating requirement changes the design requirements for equipment. ...
To minimize foam, they needed to reduce the net volume of air and oxygen gases that were being bubbled into the culture medium. The rotameter that Protein Design Labs had been using was not adequate for measuring the low flow rates needed to prevent excessive foaming. ...
It was shown that oxidation of sulfide in the influent was completed in the first layer. The result of the oxygen uptake rate test with an ammonium nitrogen substrate suggested that the ammonium oxidation rate was affected by the condition of dissolved oxygen (DO) or oxidation–reduction potential (ORP). ...
Introduction The Oxygen Uptake Rate (OUR) by the bacteria in Activated Sludge is one of the most significant measures available in wastewater management and a new generation of sophisticated online OUR multi-parameter instruments linked to Plant Control Systems and the Internet of Things is planned to deliver the next step change in Environmental ...
This makes it important to proactively increase nutrient feed rates so the bacteria can continue reproducing in sufficient quantities to handle the load. ...
Physical models were built, mimicking typical sewer drop structures and allowing different types of drops, drop heights, tailwater depths and flow rates. In total, 125 tests were performed. Based on their results, empirical expressions translating the relationship between the mass transfer of oxygen and physical parameters of drop structures were established. ...

After an adaptation period from the shift to pulse feeding, the effect of an increasing organic loading rate (OLR) and volume exchange ratio (VER) were investigated one after another. Remarkable changes of the specific oxygen uptake rate (sOUR), microscopic structure, sludge volume index (SVI), SVI30/SVI5 ratio, and settling ...
Following new trends we applied oxygen uptake rate (OUR) tests as well as long-term tests (in two batch bioreactors systems) in order to assess the biodegradability of textile wastewater. ...
Each of them can go for specific applications and most of the times they used to be combined in a wide fan of studies. Measurements OUR (mg 02/l.h): Oxygen Uptake Rate. SOUR (mg 02/g.h): Specific Oxygen Uptake Rate. DO (mg O2/I): Dissolved Oxygen pH - in BM-Advance - ...
Introduction The nitrification processes control must be based on a sufficient removal substrate rate to fit the actual hydraulic retention time of the biological reactor available for nitrification: Nitrification rate = ammonium-nitrogen uptake rate (AUR) Either the nitrification rate is the correct on which ...
